Acidophilus is a generalized term for a group of probiotics or beneficial bacteria essential for maintaining a healthy microbe population in the intestinal environment. These friendly bacteria supplements are comprised of one or more of the Lactobacillus acidophilus, lactobacillus casei, lactobacillus bulgaricus, bifidobacterium species and streptococcus thermophilus cultures. These bacteria are available in both dairy and nondairy based products.

The reason acidophilus is so beneficial in preventing bad breath is because it addresses the source of most of our health issues. Intestinal floral imbalances cause bad breath because improper functioning of the digestion results in candida. This yeast overgrowth extends outside the walls of the intestines. Once it enters the bloodstream, it contaminates areas of weakness and compromises the immune system.

Bad breath is a common indication of poor overall health or some particular disease or condition. Bad breath, or halitosis, can originate from many different sources. However, acidophilus, along with a few other remedies can stabilize any imbalances that would result in bad breath.

When food is not digested properly, the growth of odor causing bacteria explodes within the system and overtakes the healthy bacteria necessary to maintain balance in the digestion. Acidophilus infuses the good, beneficial organisms back into the digestive system. This allows for the return of a proper functioning immune system.

These digestive imbalances can also create build up of debris and bacteria accumulating in the back of the mouth. Nasal drip, lung and respiratory conditions contribute to bad breath as well. Allergies, dry mouth, cavities, unhealthy gums are a few oral conditions that supply the mouth with odor causing bacteria. Though these conditions seem isolated from digestive disorders, improper digestion is the initial cause.

A putrefactive bacterium from undigested food produces gas that is relieved through the breath. Animal proteins and fats are a major contributor to this condition, causing improper digestion of all foods the body tries to break down. This in turn prevents the liver and kidneys from properly eliminating toxins, resulting in further and more extensive forms of halitosis.

Other major contributors to bad breath are the consumption of antibiotics, chlorinated and fluoridated water and pesticides from our food. These items kill off the intestinal flora. Our modern culture and diet has created an internal environment devoid of essential, friendly bacteria.

This condition causes the breakdown of the integrity of the intestinal function. For example, whenever a series of antibiotics is taken, the patient should immediately follow the medication with a series of probiotics.

Regardless of the source of bad breath, acidophilus is an excellent preventative, remedy and cure for halitosis. By implanting new colonies of beneficial bacteria, you will reduce the system’s acidity, and thereby inhibit growth of future destructive bacteria.

Acidophilus is available in several forms. Yogurt and kefir are excellent sources as long as the product specifically states that it carries “live cultures.” Sauerkraut is another excellent source available in most stores.

Acidophilus prevents constipation very well. I had been having issues with that for a long time, but after I started taking acidophilus tablets, I stopped having the painful bloating and gas that constipation can cause.

I was so glad that something finally worked. I had been dealing with bad breath from the buildup of toxins in my body, and no peppermint gum or mouthwash could fix that. Acidophilus did, though.

@giddion – Yes, acidophilus prevents candida from flourishing. I had a bacterial infection that required antibiotics, which can actually cause yeast infections. So, my doctor told me to eat plenty of yogurt or take a supplement after I finished the antibiotics.

I hate the taste of yogurt, so I went with the supplement. I had to keep it refrigerated to preserve the probiotics.

I have noticed before that during yeast infections, I do have bad breath. It's good to know that acidophilus can help with that.

It's strange to me that the acidophilus bacteria in yogurt can prevent bad breath. Yogurt smells really bad, and I have a weird taste in my mouth after I eat it.

You just wouldn't think that something that smells and tastes that funky would prevent your breath from smelling funky, too. I suppose since it's all internal, it really doesn't have anything to do with smell on the surface.

I never knew that acidophilus would prevent bad breath. I did know that it could prevent yeast infections, but I had no idea that they could lead to bad breath.

I was prone to getting yeast infections, and my doctor told me to try taking an acidophilus supplement daily. She said that while it couldn't cure an active yeast infection, it could prevent further ones from developing.
