Probiotics are healthy germs which a person takes to improve intestinal and overall health. According to the World Health Organization definition from 2001, probiotics are "live micro-organisms which, when administered in adequate amounts, confer a health benefit on the host."
Current probiotic products fall into three categories:
The health benefits of probiotics may include:
The most common bacteria included in probiotics from this category include strains of Lactobacillus and Bifidobacterium. These strains generally require refrigeration. Because they are derived from bacteria living in human intestines, many strains may repopulate and remain in the intestines over time.
These are also called spore-forming probiotics. Common spore-forming probiotics include strains of Bacillus bacteria. These bacteria exist in heat stable spores outside of the intestinal tract. This means they do not require refrigeration. They are also acid stable which improves their chances of reaching the intestines. Unlike human intestinal bacteria like Lactobacillus and Bifidobacterium, these do not appear to repopulate the intestines. They seem to work by supporting the growth of healthy bacteria in the intestines. They may also work by helping Lactobacillus and Bifidobacterium probiotics live, grow, and function in the intestines.
Human intestines include a healthy yeast called Saccharomyces Boulardii (Sacro B). This probiotic is especially useful for the treatment and prevention of C. Diff infections in the intestines. C. Diff is a bacteria living in the intestines that can grow too much when a person takes antibiotics. It can lead to severe diarrhea. For more information about this condition see C. Difficile Diarrhea: Prevention and Treatment
"Generally throughout this site, I do not recommend specific poducts and brands. However, with probiotics, the quality of the product matters. Below I present products and brands which use high-quality strains of bacteria with a beneficial scientific-based track record. Unfortunately, many probiotic products which I do not include here do not use strains shown to work." Marty Ross MD
To prevent Candida yeast overgrowth in the intestines and to keep a balance of good intestinal bacteria, probiotics may be helpful. Herbal and prescription antibiotics can kill healthy intestinal bacteria which can lead to yeast overgrowth, immune system imbalance, and poor digestion with loose stools.
In some with loose stools on antibiotics, it may be very helpful to increase probiotics to stop this problem.
Use either a soil-based probiotic with Bacillus species or human intestinal bacteria with Lactobacillus and Bifidobacterium. For greater intestine dysfunction, consider using both types. The advantage of a soil-based spore-forming probiotic is that it does not require refrigeration. Be sure to use brands which use strains that are scientifically proven effective.
The strongest way to promote healthy intestines while on herbal or prescription antibiotics is to use soil-based spore forming probiotics along with human intestinal bacteria-based probiotics.

Based on my experience managing Lyme disease, when someone has intestinal yeast overgrowth, it is useful to use both a soil-based probiotic and a human intestine-based probiotic at the same time.
