Probiotic is the name microbiologists gave to the living "friendly" microorganisms found in the gastrointestinal (GI) tracts of healthy individuals. The term probiotic means "for life" and there are many Probiotics with therapeutic properties. Most probiotics are bacteria, but some yeasts and fungi may also fill this role. The two most popular groups of bacteria are Bifidobacterium and Lactobacillus, both of which contain multiple species. Bifidobacteria is helpful in treating infant diarrhea. Lactobacillus bulgaricus makes milk products sour in order to extend their shelf life (think yogurt) while Lactobacillus acidophilus helps maintain intestinal health and is a natural Antibiotic. Probiotics are essential to proper development of the immune system and to the digestion and absorption of food and nutrients.
A healthy, effective colon requires the correct
balance of friendly bacteria.
