Lactobacillus bulgaricus is a friendly bacterium that normally resides and prevents other harmful bacteria from growing inside the intestinal tract.
These mechanisms include reducing intestinal infections by excreting metabolic end products-- such as acids --that change the pH of the GI tract, thereby helps in breaking of complex enzymes such as lactose.
It stimulates the growth of other beneficial bacteria, and thus serves as a culture starter in yogurt and probiotic manufacturing. Probiotics are commonly used to treat digestive problems.
Supplementation of it can be employed to boost oral health in the sense of improved dental protection, reduced instances of periodontal diseases, and suppression of Streptococcus bacteria thereby protects in infection caused by them.
