Probiotics can support digestive and immune health. Intestinal flora consists of microorganisms that live in the digestive tract. Intestinal flora's primary benefit is energy extraction from the fermentation of undigested food. Intestinal bacteria also play a role in synthesizing complex sugars and vitamin synthesis.
 

   The digestive tract also contains pathogenic bacteria that can produce toxins. A major factor in human health is the balance between good and bad bacteria. Helpful, good bacteria compete with pathogenic bacteria, assisting in the intestinal balance.

   L. Bulgaricus has been shown to survive passage through the digestive tract in amounts sufficient to produce beneficial effects on digestive health.

   A large percentage of body’s immune system cells are contained within the digestive tract as well. Intestinal flora has a continuous and dynamic effect on people’s gut and immune systems. The bacteria stimulate the gut to produce antibodies against bad bacteria. The immune system recognizes these antibodies and fights harmful bacteria.
