Lactobacillus bulgaricus is a type of beneficial bacteria that is commonly used in the production of yogurt and other fermented foods. It is a "friendly" bacteria that helps to maintain a healthy balance of bacteria in the gut.
In protein powders, Lactobacillus bulgaricus may be added as a probiotic supplement to support gut health and digestion. It is believed to help improve digestive function, boost the immune system, and support the body's natural defenses against harmful bacteria.
Lactobacillus bulgaricus is generally considered safe when consumed in recommended amounts.
