An Acidophilus probiotic health supplement is a digestive aid that consists of live microbe organisms called acidophilus. Probiotics can really be various forms although the most common is acidophilus. There are over four hundred different microorganisms living in a intestinal tract of humans, including Lactobacillus and Bifidobacterium.

Acidophilus probiotics are thought to be effective by many people as they are regarded as "good" bacteria. They are believed to improve healthy digestive tracts by:

Keeping the expansion of "bad" bacteria under control
Boosting the function of the body's defence mechanism
Protecting the digestive system tract
Developing important vitamin K
