Description:
Over 100,000 billion bacteria ( more than 500 species) live in the human gut. Human gut flora
contain friendly and harmful bacteria. Probiotics are believed to play very important roles in
regulating proper intestinal function and digestion-by balancing intestinal microflora.
The Food and Agriculture Organization of the United Nations and the World Health Organization
have defined probiotics as "live microorganisms which when administered in adequate amounts
confer a health benefit on the host" (FAO/WHO 2002).
Lactobacillus and Bifidobacterium are probiotic, or "friendly bacteria" to maintain a healthy
digestive tract (stomach and intestines)
