Garcinia cambogia is a small fruit that resembles a miniature pumpkin. It is indigenous to India and parts of Asia, and an extract from its fruit and rind is popular in many natural weight loss products. The extract is hydroxycitric acid (HCA), claimed to suppress appetite and enhance fat-burning. Animal research supports these claims, but subsequent human trials have been equivocal.

The theory behind garcinia cambogia is that HCA inhibits an enzyme called citrate lyase that helps turns excess carbohydrates into fat. By inhibiting this enzyme, it is believed the body instead boosts carbohydrate oxidation, or simply put, burns the extra carbs. In extensive animal studies, garcinia cambogia was found to reduce food intake by suppressing appetite, as well as to decrease body fat. Human trials have been less clear. While some double-blind studies using garcinia cambogia and a placebo showed the HCA group as doubling or tripling weight loss over a 12-week period as compared to the control group, other studies showed a less promising result.

The Journal of the American Medical Association (JAMA) published such a study that used a daily dose of 1500mg of HCA over a 12-week period on healthy, overweight adults. At the end of the study, the group receiving garcinia cambogia did not see statistically different weight loss from the control group. However, this study has been criticized by some, with the claim that the high-fiber diet used in the trial likely interfered with the body’s ability to absorb HCA. Unfortunately, the study did not test the subjects to see whether HCA was found in the cells where it becomes active.

Garcinia cambogia reportedly does not have any known adverse effects in healthy adults, but there are some people who are advised not to take it. According to experts, this includes children, pregnant and lactating women, those diagnosed with diabetes mellitus, and people with Alzheimer’s or other forms of dementia disease. In the case of Alzheimer’s patients, it is thought HCA might form acetylcholine in the brain, while diabetics could be affected by HCA’s tendency to lower blood sugar. Conversely, in healthy adults this latter effect can purportedly curb cravings for sweets and carbohydrates.

Garcinia cambogia is usually sold in capsule form, standardized to include a percentage of HCA, the active ingredient. Only brands standardized to 50% or greater HCA are generally recommended. For maximum effect, the daily dose is divided in three parts, taking one or more capsules 30-60 minutes before breakfast, lunch, and dinner.

Some manufacturers claim garcinia cambogia must build up in the system before the full benefits can be realized. It has also been suggested that HCA might help people who have already attained their ideal weight to maintain it. The Food and Drug Administration (FDA) does not regulate garcinia cambogia. People who are considering augmenting a healthy diet and exercise regimen with herbal aids like HCA should see their physicians for personalized advice.

I have been using it for a little over two months now. I have so far lost 5kgs. not a vast amount I know but a good start!

By anon989520 — On Mar 10, 2015

I have been taking GC for six months from a company called Power Up Garcinia Cambogia. It is a proprietary blend 400 mg. Other ingredients in the capsule are gelatin, calcium and magnesium. It was offered on the internet and I ordered it.

I've had no side effects whatsoever and it has definitely curbed my appetite. There has been no radical weight loss, but it has kept me at my normal healthy weight of 135 which has previously been impossible for me to do. I'm a believer so I will carry on. I feel so bad for all these others who are experiencing such dreadful side effects. Maybe it's from something else they are doing?

By anon964419 — On Aug 05, 2014

Don't use it - it gave me chronic back pain and abdominal cramps. I lost a few pounds but the pain and harm to my body were not worth it!

By anon958539 — On Jun 28, 2014

I bought the 100 percent Pure Garcinia Cambogia from the US. I am on day four of taking this supplement taking two 1000mg tablets one hour before breakfast and then again before tea. I have had no real side effects from these tablets except for sore back muscles, which usually kick in about one hour after taking the evening tablet. I have had ho headaches (am a chronic headache sufferer) no pains in the stomach or any concerns of constipation or sleep issues. I will continue to take these tablets as I have lost 1.5kgs in this short period of time but monitor the back pain.

By anon954752 — On Jun 03, 2014

Finally! A site that has some real reviews, and not just listing a bunch of "accredited" information nestled between links to purchase.

By anon954751 — On Jun 03, 2014

Most of these post are made by people who couldn't lose weight! I am sure of that! It works if you flow and do it right. On the other hand, there's nothing like doing it the natural way.

By anon947126 — On Apr 24, 2014

I think this site is a bit absurd. If you have a medical illness, it doesn't take a rocket scientist to tell you that you need to consult your doctor before trying something. If you do the research (in medical journals which you can access at pubmed, you will see multiple studies done on the supplement with and without the potassium and calcium and chromium.

I would stay away from the ones containing these additives, since calcium supplements can cause stomach cramping and bloating or diarrhea. Potassium is a needed electrolyte, but you get this from vegetables and fruit. Too much potassium can affect your heart, so if you take a multivitamin with it, you may be taking too much, but if taken properly you should be fine.

Again, research each ingredient before you purchase the product and your best bet is to get the GC which contains 50-60 percent of the HCA, with no added stimulants such as ginseng or caffeine (which some brands contain). Research what you're putting into your body and talk to your doctor. And you need to drink a lot of water with this supplement and your headaches will likely improve.

The product won't work if you eat high fat foods and fast food. You need to improve your diet and eat fresh fruits and veggies and stay away from simple carbohydrates such as white bread and pasta.

I do not endorse or promote any product. I am a doctor telling you, begging you to do your research. Look at the actual scientific data available and not these forums where you don't know who's putting up fake posts or not.

By anon943680 — On Apr 02, 2014

I've been on Garcinia Cambogia for about three weeks now and a week ago, my eyes started twitching sporadically. This has gone on for a week. After reading some of the side effects of this product, I think I'm going to stop for now. Hopefully my eye spasms go away.

I took an all natural extract, 50 percent HCA, and it had potassium and calcium in the supplement to help better absorb it.

By anon939095 — On Mar 12, 2014

Since I have been using GC, I get terrible headaches and feel hungry almost like I never had a meal the whole day. I'm going to stop this. I can't put my health at so much risk. I thought this was a great product.

By anon936782 — On Mar 03, 2014

Are the people with bad side effects taking an organic version? If not, maybe look into that. I have bought this and am yet to start on it, but I do believe that if it is a natural substance that has been used for years in some countries then it can't be the garcinia cambogia giving the bad side effects. Also, most weight loss products will cause diarrhea. That would be your body cleansing itself, but I'm not an expert.

By anon936734 — On Mar 02, 2014

I took this product three times a day for almost one month. I suffered a severe cutaneous reaction, leaving me with horrific pain, welts and itching all over my body. I had to go on oral steroids, in addition to a topical cream. I have now been off it for one week, and I have muscle swelling in my wrists and calf so bad I cannot bear weight and lack strength.

I thought I would be slowly feeling better, but that is not the case. Clearly, this poison takes a long time to clear from the body. I have no info on the half life. Very frightening.

By anon934315 — On Feb 19, 2014

To all you pregnant and breastfeeding mothers: Read these comments and side effects. Do you want to risk the life of your child? No, you are not supposed to take this drug while breastfeeding or pregnant! Seriously, people, do some research from a reliable source! Ask your doctor, or look on the bottle where it tells you not to do it if you're pregnant or breastfeeding! Asking advice on this board and basing your child's life on it, are you out of your minds?

Most important of all, don't be selfish! If you want to take this crap, wait and formula feed your child after it's born so you can take it. Do not breastfeed! Be careful with this.

By anon929504 — On Feb 01, 2014

I took one pill and in half an hour, I felt horrible! I had a splitting headache, nausea and weak legs. I barely made it through the day at work. I do have headaches occasionally but with the other symptoms I thought I must be getting the flu, but I had a flu shot so that didn't seem likely.

I felt better by evening so I didn't take another pill. Everything was gone by the next morning except a little residual headache. So I don't think the GC was connected to the headache, but the rest could be. I'm concerned enough that I'm throwing the stuff away. Granted, I probably could lose weight taking it, but only because I felt so awful I couldn't eat all day.

By anon928281 — On Jan 27, 2014

I have stopped taking Garcinia Cambogia after four days due to the following side effects I had:

Restless sleep. I couldn't sleep, and would lie awake every 1-2 hours and then drift off for half hour. I take 1/2 sleeping pill one night and only got 3 hour block of sleep.

2. Constipated/diarrhea. From day two onwards, I didn’t have any proper bowel movements, only some small watery movements.

Heart rate changes. It felt like my heart rate had increased. While I didn’t check my pulse timing or blood pressure, I could tell something wasn’t quite right.

No weight loss. I have been eating healthy portion sizes at regular intervals and been exercising. In fact I was actually .2kg heavier on day four (could be due to no bowel movements though).

5. Headaches. I had bad headaches, and day five (this morning) is by far the worst. The pain is right in the temples that radiates around the forehead.

Nerve pain behind knees. I sometimes get this, but take a magnesium pill and it sorts the yucky feeling out. When I took the magnesium it did nothing and I kept having to shift my legs around.

I do not recommend this product or any slimming aids. Healthy eating and exercise is the way to go.

By anon924969 — On Jan 08, 2014

Anyone else have chronic constipation? I started on Sunday and had diarrhea. It is now Wednesday night and I have not had another bowel movement. Also I have a headache, on both sides of the head, not the normal frontal sinus area where I usually get them. Should I stop taking this or persevere? I am worried and curious.

By anon924915 — On Jan 08, 2014

I bought the live skinny garcina cambogia and was taking two pills a day. I had a doctor's appointment for a check up and he flipped out and made me take an EKG. My heart rate was 142 then 60. It was crazy. He told me to quit taking the garcina cambogia immediately, and now my heart rate has returned to normal. So, for those people that say it's not true, it affected me this way. Be careful. I am 53, and don't smoke or drink.

By anon359326 — On Dec 16, 2013

I have been taking Garcinia Cambogia for three days. I take two pills a day which equals 1000mg. I take one 20-40 mins before lunch, one 20-40 mins before dinner. The first night my bowels cleaned themselves out and I felt better afterwards. On the third day, I got a headache and my eyes were bloodshot and I had minor muscle cramps in my legs. However, after reading up, I found out these are just signs that the body is detoxifying, as the toxins in the body are released into the blood and should stop soon.

I also have colon cleanse which I will take once or twice a week to help get rid of toxins, and drink plenty of water. In regards to weight loss, my belly feels flatter already (I have the post baby belly fat) and I will continue to take for three months, provided the headaches ease off, and I'm hopeful they will.

By anon356150 — On Nov 22, 2013

As an internal medicine specialist (Clinical chemist/microbiologist/ histologist/hematologist/cytologist and immunologist, I can never recommend anything that suppresses natural body enzymes or their natural functions. Dr. Oz is nothing more than a quack!

Anyone who listens to a surgeon (who, by the way, is paid to cut, not diagnose), is just plain lazy and looking for a quick fix rather than doing it the natural way, through hard exercise and eating a healthy, non fattening, low carbohydrate diet.

As for those corporate stooges representing this time bomb in a pill, commenting on here about me and others having an ulterior motive or representing some other health food company I say this: I am an extremely well schooled individual who has sworn the oath of Hippocrates to do no harm through my practice of internal medicine.

Mess with the body's homeostasis and it will revolt on you in ways you cannot imagine, and usually with disastrous consequences. Remember this: when we were dragging our knuckles we ate nuts and roots and berries and meat, not Twinkies and pizza, greasy chicken, etc.

By anon354667 — On Nov 10, 2013

I've been taking GC for two days now. The only issue that I've had is regurgitating the pill and throwing it up because of acid reflux, but my fiancé has been taking it for almost a week and he is looking a lot more lean. He's losing the weight. It is a proper diet and exercise, but when you take this, I know people are saying they have side effects. The research I did shows the side effects usually last between a week to two weeks with the headaches and nausea because this is a new herbal product you're putting in your body, but there's only two brands that are recommended.

I you guys listen to Dr. Oz, he said there's two things to look for in the ingredients and make sure the website shows the labeling. If they do not show the labeling, then it's one of the ones that is not going to work. The two that we ordered were one brand: Whole Body Research, which is what my fiancé and I are taking right now and it's working wonders. It says it contains the ingredients that we need, but it’s saying it needs to have calcium and potassium and it needs to have at least 50 percent of the Garcinia cambogia, which is 1500 milligrams.

I usually take it two or three times a day. Instead of taking it 30 minutes before the meal, you take it an hour before meals, and like I said, I haven't had any problems with the kidneys or anything like that. Honestly, some of you might have gotten a hold of the brand that is full of it. There are I think, about 78 brands out there that are not good and that's why you guys are not seeing results.

The second brand is Premium Quality Garcinia cambogia, and 100 percent pure natural Garcinia cambogia is what it says. These are the only two sites that showed the label, so if you're going to try it look for the label, that is the most important thing to look for. If they show the label, you can see the ingredients and then you can order that one. These two are the ones I’ve tried that we ordered.

Like I said, the first one is the Whole Body Research, which we’re trying. I have severe acid reflux with a hiatal hernia so I'm not supposed to be taking it but I'm on day three and my body is finally getting used to it so if I can handle it I'm pretty sure any of you all can.

I've had to make a lot of sacrifices. I've had a lot of health issues and I've been in and out of the ER. I was told I can do this. Another thing that might help people is because it is trying to detox your body and it does do a little bit of cleansing. Try to take it with the Renew Life Cleanse Smart Morning and Evening Formula. Do the morning and evening formulas for three days before you take the GC. What that does is cleanse your liver, your lymphatic system, your digestive system your lymph nodes and it’s like a whole internal cleanse that will help balance it when you decide to take the Garcinia cambogia. Hope this helps all of you guys.

I took GC for two months, lost 25 pounds and I almost died. I had pains in my side and back muscles. I had headaches. I got really bad and went to the hospital because I wasn't producing insulin. I had kidney stone surgery, now have two stents and a blocked bike duct. I also had acute pancreatitis. I spent thousands in medical bills. I've been off it for two months and I am gaining the weight back.

By anon352302 — On Oct 21, 2013

I've been taking this for about two weeks now and have lost seven pounds, however, I now have a tightening in my throat that feels like it's closing. I also have allergies so I've taken Benadryl but nothing is helping. Could it be the GC?

By anon352125 — On Oct 19, 2013

I started taking this product three days ago. I have been having ones three times a day. I have had diarrhea, headaches, couldn't sleep until after 1 a.m. last night, was dizzy and had blurred vision last night. I felt like I was off my head on drugs and had to go to bed. I just lucky my son was in bed at the time.

I have taken another one this morning and feel okay, just a bit nauseated still. I think I will keep it going for another few days and see if the symptoms go away. Maybe it's just my body cleaning itself out. Hoping it works!

By anon349833 — On Sep 29, 2013

I've been taking this stuff for three weeks now. While I find it does suppress my appetite, I haven't lost a single pound. I exercise at least three times a week and haven't changed my workout regimen since I started taking it. I don't need to lose a ton of weight -- five pounds would be fine, and 10 would be awesome, but I'm starting to think I'm wasting my time with this stuff. I have no side effects, and the product I'm taking doesn't contain any fillers. I don't understand why I'm seeing no results.

By anon347609 — On Sep 08, 2013

For people getting headaches: it did the same to me, but I work at a store that sells it and I've seen tons of people dropping weight. For ladies with high or low estrogen levels, which could also be a contributor to high sugar levels, it will give you a super headache. I'm not saying that toxins are usually the reason, but having experienced it myself, I knew it was a different kind of headache, and sometimes when you have had a certain amount of sugar in your diet, your body will also have side effects if getting rid of a usual supply of something. My headaches are gone, and my hormones are also calming without all those insulin spikes. I'm losing weight and feeling better. Women who experience anger probably should use progesterone cream. That stuff is awesome; just follow the directions.

By anon347011 — On Sep 03, 2013

I am normally a very fit person. I have a set routine, but since taking garcinia cambogia, I have no longer been able to do that routine as I have been experiencing shortness of breath and unusual muscle aches.

I would advise anyone who exercises regularly not to take this. I have been far more tired than usual, also. I just threw mine away.

By anon346889 — On Sep 01, 2013

@digimon, Post 14: I understand why you would think that way about the diabetes warnings. However, the concern is valid. Here's why, from what my diabetes instructor told me: diabetes is not a disease of high blood sugar; it is a disease of the body not being able to maintain a balance of sugar and natural insulin. What happens in diabetes is the sugar spikes and drops and the body can't make enough insulin (or possibly, use enough) insulin to keep everything balanced (like not having a good balance of air and fuel in a car), so the body can't function properly.

For me, my blood sugar levels should never drop below 82 or rise above 150. If my sugar drops below 60, there's a good chance I could slip into a coma or die. It seems that there is some concern and possibly not enough information about how much GC can possibly cause the sugar to drop, and therefore it could possibly be a risk for a diabetic. Better safe than sorry.

Can you take it while on Synthroid?

By amypollick — On Aug 22, 2013

@anon345828: I'm really sorry you spent your money for this. I've never taken it and don't know what it does, but I know what my endocrinologist told me: Dr. Oz is the most dangerous man on TV. My doc said if Oz would just stress to people to eat healthy and exercise, he wouldn't have a problem with it, but he said Oz is just a shill for all these people with the latest cure-alls. He has actually had patients tell him that his diagnosis/advice/treatment couldn't possibly work because Dr. Oz said something to the contrary! And if you knew my endo, you'd know just how foolhardy that kind of statement is.

I wouldn't trust Dr. Oz to tell me my house is on fire.

By anon345828 — On Aug 22, 2013

This stuff is worthless. Dr. Oz should be ashamed of himself for touting this fraudulent product. I have been exercising and eating 1,500 calories a day for three weeks. I have lost two pounds taking the garcinia cambogia as directed. I've had headaches and no weight loss.

I generally would not spend $100 on a diet pill, but Dr. Oz gave it such a fabulous review, I thought, why not? He is a quack - and I'm the same weight, just poorer.

By Kar311 — On Aug 10, 2013

Are there any type 2 diabetics who are taking Garcinia Cambogia regardless of these posts? If so, do you have any side effects?

By anon343885 — On Aug 03, 2013

This sounds very unsafe and very questionable. Dr. Oz, any comments on these posts?

By anon343145 — On Jul 27, 2013

I have tried Pure Garcinia on and off for about five months. (I bought it according to the specifications Dr. Oz spoke of). I felt good on it at first, but saw only a three pound weight loss. I would occasionally burp and tasted a smokey taste. One day, five minutes after taking it I burped and I opened my mouth, and smoke came pouring out of my mouth! My 15 year old and I both freaked out!

I stopped it for two months, went back on last week, and I have had horrible headaches every day. My mother tried taking it and she had the opposite effects of what it's supposed to do. She became miserable! So I guess I am stopping this stuff for good.

By anon342812 — On Jul 24, 2013

I have been taking the Pure Garcinia Cambogia for less than a week. I have severe headaches daily, multiple times a day. It is disappointing. I do not know what I am going to do. I don't think however that if the headaches continue that I will be able to keep taking the GCP. Unfortunate.

By anon342400 — On Jul 20, 2013

I've taken GC for three days and have had a constant headache. I rarely get a headache so I can only assume that it is being caused by taking GC.

I think any product that causes headaches should be avoided. A headache is a sign of some sort of toxicity, and it involves the brain! Pay attention to what your body tells you. For me, it's a no brainier. I'm saying goodbye to my headaches and the pills that caused them.

By anon338715 — On Jun 17, 2013

Can obese teens take this?

By anon336226 — On May 27, 2013

For ladies who are pregnant or breastfeeding, please don't take this at all. No current drug to date has been tested for pregnant women for the main reason nobody can predict side effects of any drug on pregnant women. No ethical company would venture into that form of testing and nobody would know how this medication can affect the body of a pregnant or lactating woman. Please don't take it.

By anon335793 — On May 23, 2013

I have heard many reports of horrible side effects on this product and I am nervous about taking it. I have a coworker who is in health and fitness and she sells all natural supplements that were referred to her by her personal trainer. Do your research, guys! Don't take products that are mixed with other ingredients that can be potentially harmful.

By anon335132 — On May 17, 2013

I have taken it three times now, and I will never take another pill ever! I have had the worst stomach cramps and diarrhea in my live.

By anon334202 — On May 10, 2013

It sounds reasonably harmless, although some of the posts sound as though they are coming from supporters of another product or company that uses another product. Obviously, we are not all the same, so I would suggest giving it a go under medical advice and to all the mockers, I would ask if they went to a doctor to find out if GC caused the side effects or just their minds.

By CutieKimmy — On May 08, 2013

I lost over 12 pounds in the first two weeks using Garcinia Cambogia and between four and five pounds every week after, while just walking about a mile a day.

I am very happy with the results and can deal with the few relatively minor side affects I have experienced. I have suffered from some minor irritable bowel/cramping and very loose stools that seem to come and go suddenly. This has not been an issue long as I stay close to restroom facilities. I have also experienced some red, blotchy spots on my face and chest and some irregular hot flashes. Really, the most worrisome of my side effects has been the patches of thick, dark, coarse hair that began sprouting up on my buttocks and upper back.

I am still very happy with Garcinia Cambogia and would recommend it to anyone, as it has contributed to my significant weight loss and substantial suppression of appetite. The irritable bowel/cramping and blotchy spots should clear up after I reach my goal weight and stop taking the supplement. And I can just shave the excess hair off or maybe get laser hair removal. Really, it’s a small price to pay to lose a significant amount of weight.

By anon333149 — On May 03, 2013

Post #36 has made my day -- funny stuff. I have not started taking yet but you people need to understand that by nature, the majority of the post will be negative because it's easier to give negative feedback than positive. Just try it. For about $30 dollars is a fair risk to take if it works!

By anon332885 — On May 01, 2013

I took it for six weeks and my liver enzymes (AST/ALT) doubled. I threw it away!

By anon332062 — On Apr 26, 2013

Great post! My Mother had been using green coffee beans to lose weight until she heard about Garcinia Cambogia on the Dr. Oz show. She says Garcinia Cambogia is better.

By anon331936 — On Apr 25, 2013

I took it for two weeks and I had a bad reaction with terrible hives all over my body for three days.

By loriinsj — On Apr 25, 2013

I suspect that risks for Garcinia Cambogia may depend on the brand. Some have stimulants like caffeine or gaurana which can boost energy, but also heart rate which can be unsafe for some.

National Standard says it is safe when consumed orally.

The reason it isn't safe for diabetics is because some diabetics or those on meds are at risk of low blood sugar levels. If the blood sugar drops too low, it can be fatal. A pre-diabetic or type II diabetic may not have that issue, as the illness is different.

I would think the best bet here would be to test the blood sugar at regular intervals after taking it to be sure it doesn't go too low.

By anon331850 — On Apr 25, 2013

I use Garcinia Camgogia and yes have experienced one side effect of diarrhea. With that, said I asked my doctor about this and she said that it will stop about a week into using it and she was right. She attributed the diarrhea with the body cleaning itself out, which made sense. It has helped me with my weight loss. I have hypothyroid disease (well I actually don't even have a thyroid anymore) and weight gain is easy but weight loss is really hard. This has helped me considerably.

By anon331567 — On Apr 23, 2013

Don't know if I've had any weight loss after two weeks, but I am now experiencing sore muscles all over which has been going for a few days. I may have to stop taking it.

By anon331064 — On Apr 20, 2013

I have been taking this for 12 days. The first day I took a whole pill and was so over stimulated that I could not get any paper work done all day. I did, however, have an energetic workout on my Nordic Track. The second day I reduced the dose to only half of a pill. That was easily tolerated. I continued at half a pill a day for seven days. Then four days of one whole pill per day.

One the evening of the twelfth day, my pulse shot up to 180 beats per minute after going out to my car to grab a bag of groceries. It was a short walk of only 60 steps or so. I was out of breath and had a pain in my chest which I thought was my windpipe. After about three minutes I was able to catch my breath and decided to check my pulse. It was pounding away at 180 beats per minute. It took about an hour for it to settle down to 100 beats per minute and by then it was past midnight, so I went to bed.

I am afraid to use this product any more. Too bad. It did a good job of suppressing my appetite.

Don't take this. My friend's mum died from it. Don't believe what everyone says "that they really work." They may lose weight, but not the natural way. It's really bad for health. A good diet and exercise will help you better.

I have been taking Garcinia Cambogia as directed for two weeks and have not seen any results. I go to the gym four days a week and also eat very healthy. How come some people seem to loss and others don't?

By anon328548 — On Apr 04, 2013

I started Garcinia Cambogia Extract, rightway brand, all natural no additives, no added ingredients, 50 percent HCA. I feel a little light headed and that's it. No cramps, no pain, no other symptoms so far. I guess it affects different people differently. We'll see what happens.

By anon327883 — On Mar 31, 2013

I've been taking it for a few weeks now and I have literally lost 0 pounds.

It's kind of irritating me. I take two pills daily, 30 minutes before a meal on an empty stomach and nothing!

By anon327802 — On Mar 30, 2013

I've been taking it for two weeks. I eat half as much as I used too and have lost 10 pounds. I have no side effects. Go for it.

By jmsmithrn — On Mar 27, 2013

My husband and I just completed the first bottle of Pure Garcinia Cambogia, and we are not having any problems. We have two bottles to go, we take them as prescribed on the bottle two on an empty stomach daily.

My husband is diabetic on a small dose of metformin and takes a lose dose of lisinopril for hypertension-no issues with low blood sugars and he is an avid daily exerciser. I have celiac disease, Hashimoto's thyroiditis, and I am IgA absent/deficient. We have had no problems.

I am constipated, but have been so for some time because of my thyroid. You are supposed to take this for no longer than 12 weeks. There have been no long-term studies for safety past the 12 weeks. The numerous short-term up to 12 week studies show this all natural dietary supplement that comes from the rind of the fruit to be safe with some mild symptoms.

There are many people out there with co-morbidities who have gained weight because of their other health issues and they are looking for the fix all to the weight their weight problem. This may not be realistic for them. Garcinia Cambogia has potassium and calcium; these two things work together with the product as a catalyst. Anyone with kidney disease or undiagnosed kidney disease and or renal insufficiency should not use this product until consulting with their doctor or nephrologist because of the potassium.

Some of this is common sense and we ordered the Pure Garcinia Cambogia, the one we saw on Dr. Oz, who I have never known to promote anything and they clearly say this on their site that if you have other health problems you need to speak with your doc first. This is a no brainer, people!

By anon327356 — On Mar 27, 2013

Do not use this product!

I took a total of four doses over four days (not near the recommended dosage) and this product has

made my very mild hypoglycemia go into overdrive. I am going to the doctor this afternoon because I cannot seem to get by blood sugar back up to normal levels. This product is not worth it!

By anon327063 — On Mar 26, 2013

I am so disappointed. I used four whole bottles of a well known brand and have no use for it. Additionally, now I have some kidney issues and I did not mention the nausea and headache. I regret it and I am so disappointed.

By Holistic2013 — On Mar 19, 2013

Second thought. I just decided to purchase the Garcinia Cambogia Extract. However, I read about the premium information. I trust my choice of Wholefood Store, and I reserved a bottle for purchase. Everything they ever sold me naturally helped me. They know their products. Besides, I almost forgot about Internet tactics.

I am healthy but I could stand to shed a few pounds. As a full-time psychology student, I learned how people react to brainwash innocent people. A healthy policy is checking with the doctor first, especially if you are taking medication, ill, or when in doubt. Your doctor has higher medical learning of the body, and your body.

By Holistic2013 — On Mar 19, 2013

Visiting the doctor first before purchasing the product is wisdom. Everything for possible weight loss is not for everyone. Someone sent me an e-mail about the video. I located the product in Dallas, Texas.

First, I thought it best to research and locate the actual fruit if sold in Texas. I prefer the original whole fruit, which I may eat in moderation. Besides, I enjoy eating healthy with 100 percent certified organic foods as often as possible. In addition, I learned the body requires a portion of healthy fats. Therefore, I eat fresh avocados, and virgin coconut oil with MCT's.

Walking is essential for me, and the results are changing my body. When I walked, I noticed after a while my cardio was welcomed naturally and was energizing my muscles and red blood cells. One thing about walking: Jesus walked.

Anyway, after reading all the posted remarks, I decided to approach my personal weight loss naturally. I drink cayenne pepper and warm tea [8oz] one hour before I take my early morning two-mile walk. That is best for me once a week, but I also drink plenty of water. I drink the second glass of water with a hint of fresh lime juice.

I also eat fresh, certified organic cucumbers to hydrate my cells, plus a cube of fresh seeded watermelon, which also hydrates my cells. I breathe in and out at the count of twenty before rising, before I walk, and after I walk. I juice a with pear and Lacinato Kale early for breakfast. I also enjoy a healthy salad and warm lettuce soup for lunch, and a nice healthy meal for dinner. I don't eat after six, but a snack (cucumber, watermelon, or fresh baby spinach wrapped around a thin slice of fresh pineapple).

I am having a blast with natural fruits, dark-green vegetables, herbs, and seeds. I love healthy red apples, blueberries, blackberries, raspberries, dark cherries, limes, lemons, mango, peaches, kiwi, seeded Seville oranges, and plums. Almonds, walnuts, papaya, and pumpkin seeds are my favorite nuts and making a bountiful small salad is my treat. In conclusion, consulting with the doctor is smart, responsible, intelligent and mentally healthy.

By anon325883 — On Mar 19, 2013

One more supposed weight loss remedy spamming the market with no definitive proof for humans whatsoever, and loads of side effects.

I've been looking all over the net for forum discussions and I haven't even found consistent testimonials, let alone meaningful clinical studies. Whoever put this stuff on the market should be in jail.

By anon325185 — On Mar 14, 2013

I'm so on the fence about this. I guess I will have to skip this. I just came off of a kidney transplant and am desperate to lose weight. I want to try it and ask my doctor about it but I am hesitant because obviously I could damage my new kidney and therefore stand to lose a lot more than a normally healthy person.

So my question is: if this supplement is so effective, harmless and 100 percent natural, why hasn't someone figured out how to just export the damn fruit here from Asia and be done with it?

By anon324002 — On Mar 07, 2013

I have been taking this for 2 weeks and have had no problems at all. I take synthroid for a hypothyroid and it has not affected me at all. I have energy, lost weight and feel great. I have asked my doctor and he said go ahead and try it. I showed him the bottle and he did not see anything in there that could harm me. I say go for it and see what happens!

By anon323524 — On Mar 05, 2013

I can't believe how ridiculous some of these posts are. You don't even have to be a high school graduate to know most of these claims are false. I haven't used this product, but I won't let any of these so called "side effects" stop me from trying it. They all sound ludicrous.

By anon323205 — On Mar 04, 2013

I can't believe all the bad reports I'm reading. I didn't know it had such a bad effect on so many people. I've been taking the NutriGold brand, at $25 dollars/180 pills for about a month now, and I've had no side effects, and lost seven pounds. I think it matters what brand you use, too.

By anon323149 — On Mar 03, 2013

I have been taking this for a week now. So far, I am losing weight (slowly). I find that my normally addictive tendencies toward food have greatly subsided. I haven't felt the side effects others are listing above, so I'm not sure if they are taking straight Cambogia, or one of the many items on the market that have that as one of the ingredients.

I tried another supplement that also had caffeine in it. That one made me very ill. I bought the one I have based on Dr. Oz's recommendations (only Garcinia Cambogia), and haven't suffered for it as of today.

By anon321595 — On Feb 23, 2013

It made me very, very, very irritable! Sure, I had no appetite, but who wanted to be around me? Not even me!

By anon320307 — On Feb 16, 2013

I am so sorry to see that this product Garcinia Cambogia has caused horrific side affects! I am a distributor for Herbalife and my mom was thinking of getting this product, so I decided to do research on my own and see what it is all about and I am thankful I came across this website.

By anon319805 — On Feb 14, 2013

I read every post and I'm more confused than before! Some like it, some fear it and some hate it. So, with the web waiting, I guess I will investigate a site that might actually tell me something I can use!

By anon319052 — On Feb 10, 2013

I have a constant headache with the use of this product! I am miserable. I do not recommend it!

By anon318195 — On Feb 06, 2013

After a week of taking GC, I am sending it back to the company. I am so disappointed in the fact that, before I bought it, I first searched for side effects, I found none other than slight headache and Dr. Oz's glowing recommendation that it had no side effects. He actually says he gets no kickbacks from sales. He should shut up until he knows all the facts as seen here in these posts.

I have had slight headaches every day and yesterday, got terribly dizzy, and had cold sweats and diarrhea. I thought I was coming down with the flu, but all passed within a few hours. I am definitely not using this again. My GC has potassium in it, so I say be very careful and I hope you read these posts before you buy.

By anon317655 — On Feb 03, 2013

I took one dose of this today for the first time and I am feeling horrible. I have severe headache, nausea, dizziness and sweating -- not a good thing. I do not think I will continue taking this.

By anon317613 — On Feb 03, 2013

I have really bad back problems. I was in an accident a year ago, and as a result, I gained 80 extra pounds and I really want it off. I still can't do much and I was really thinking about taking Garcinia Cambogia to help but all these comments are scary. I already have heart problems now. Does any one have anything positive to say about it or know of another way or something else that's better?

By anon315913 — On Jan 26, 2013

Dr Oz is recommending this and it concerns me very much that he jumps on the bandwagon of anything that seems to arouse attention and taps into people's desperation. It is very irresponsible of him to recommend remedies that he himself has not tested. He goes by what 'manufacturers and producers' say. To me, he is unconcerned about the side effects people are suffering because he cannot be held liable but he still gets an audience which pushes up his ratings.

By anon313958 — On Jan 15, 2013

After reading all of the previous posts, I think there is a general consensus that this product is not good for anyone. I haven't used it but just by reading the side effects people are reporting, I think it would be best to avoid using this substance in any supplemental form.

By anon311176 — On Dec 30, 2012

I took it and my throat felt real tight like I was having a hard time taking a breath. I will never use these again. Horrible experience.

By anon311012 — On Dec 28, 2012

I ordered what was supposed to be the product Dr Oz recommends from a mysterious web site. Well after taking only one pill a day for three days, my stomach was upset and I had bouts of diarrhea. Imagine if I had taken the three pills a day!

I tried to return them and was told that I could not return opened products. Don't buy anything from a company called Weight Loss Punch. It was $38 down the drain for nothing.

By anon306034 — On Nov 28, 2012

I was taking a product that is very good and was trying to lose a few pounds, so I decided that I'd kill two birds with one stone and take the product geared for weight loss. I had several bouts with what I thought was choking when I took vitamins. My mother even tried to do the Heimlich Maneuver, which didn't work.

When it happened a third time, I went to emergency. I found out that the product added for weight loss was Garcinia Cambogia. You would think you could find information on side effects somewhere on the web, but I had to search for a long time. I finally found a web site that said one of the side effects in some people is a tightening and constricting of the throat that's actually caused a few deaths, although not many.

I don't care how few it was. After my reaction, I am not taking any weight loss products. I'm doing really fine on my own, since it's not caused by bad eating habits, but thyroid and back problems that made exercising difficult. I'd advise anyone thinking of trying this to be extremely careful.

By anon266455 — On May 06, 2012

I took it for two days and started having terrible stomach pains that radiated all the way through to my back.

I stopped and then thought it was caused by me lowering my anti depressant dose and so I upped the dose and was feeling great. Today I took another one and now I'm in pain again. This stuff cannot be good. Be careful, guys!

I think you should be careful and pay more attention on your trials, because there are many products which have little to almost none of the HCA. Secondly, many factors that contribute to different illnesses don't mean this will end your intake, you cannot tell the real cause apart since there aren't exact symptoms for this. You should do a placebo for some months and see what you should eliminate from your symptoms.

By anon144015 — On Jan 18, 2011

I took this and a got explosive diarrhea. It was awful, and I think working out made it worse. I soiled the entire stair climber. I cleaned it up, so they still allow me back in the gym.

I wear a diaper now when I work out, and i still get the explosive diarrhea when I work out, but at least now it doesn't make a mess and I can clean myself up in the gym shower after.

I am losing weight fast as well. I have lost 80 lbs over the last two weeks! The headaches and cramps suck, but at least I am losing weight! I was wondering if maybe I double my intake it would help my diarrhea. I mean, it's so explosive right now, I am wondering if I can get more in my system it would overcome this.

By anon142410 — On Jan 13, 2011

I take it for two or three days and I have headaches after every administration. I get up in the morning with a headache, I take an analgesic, it passes away and after the next administration the headache appears again, and so on. I have read somewhere that there are reports of toxicity in the liver. I plan to take the pills maximum one or two days and if the headaches won't disappear, I will cease the treatment.

The muscle cramps could be caused by loss of potassium, a common side effect of many prescribed medications as well as those sold over the counter. The easiest and most natural way to treat this is drink more water and eat bananas (on the advice of my pharmacist) so you don't have to resort to another prescription to control this side effect.

You can take otc potassium supplements, but many people can have heart problems and swelling from them.

In response to some of the earlier posts: If you take a supplement and it makes you feel sick in some way (nausea, muscle tremors, etc.), then you should stop taking it. Supplements are not regulated by the FDA or any other agency. The manufacturers don't have to prove that they are safe or effective before they sell them.

You are naive if you think that the manufacturers of supplements (herbal or otherwise) are any different than the pharmaceutical companies, as far as profits taking priority over your well-being.

Diabetics can be divided into two groups based on their requirements for insulin. Type 1 is Insulin Dependent Diabetes Mellitus (IDDM). Type 2 is Non-Insulin Dependent Diabetes Mellitus (NIDDM). Garcinia cambogia, I think, is contraindicated to diabetics of type 1 class. Please refer to medical books/references for further inquiries/concerns.

This is a respose for anti-diabetic use of Garcinia Cambogia. There are many herbal drugs that control blood sugar such as Cinnamon, bitter melon, gymnema - sylvestre, Banba, etc. You cannot advertise them for sugar control. Diabetes is a slow-killer and regulatory authorities don't want the consumers to rely on these poor approches to control the disease. There should be a well controlled, placebo, double-blind, randomized, clinical trial to approve or disapprove its use. For your information. Ali.

I am more concerned with the thought that HCA might form acetylcholine in the brain which can cause paralysis and muscle spasms. This has been more of the side effects I encountered.

By digimon — On Sep 04, 2009

I fail to see how the warning for diabetics not to take Carcinia Cambogia is valid. How can something that lowers blood sugar not be advantageous to diabetics? Isn't diabetes a disease of elevated blood sugar? Insulin is a treatment to lower blood sugar, and Carcinia Cambogia appears to do the same thing.

what is the effect of garcinia cambogia to the fetus if mom had taken a small amount,about 300-500mg

By anon25942 — On Feb 05, 2009

Probably the reason it isn't recommended for diabetics for reasons of lowering blood sugar is that many people regulate their level with metformin (Glucophage) or insulin. If they've already taken their dose and this further lowers their blood sugar level, there is the possibility that they could go into diabetic shock or coma. Although I doubt that could happen, I'm sure that the companies that produce this supplement just want to cover their bases.

By sreedharan — On Jan 01, 2009


Good day to you. I wish everybody a very happy and prosperous new year. In your article about the Garcinia Cambogia, it says, diabetics could be affected by HCA’s tendency to lower blood sugar.

Is it not the remedy for Diabetes, lowering the blood sugar? Then why is Garcinia Cambogia not advised to be taken by diabetic patients?
