Lactobacillus acidophilus is a type of bacteria that is naturally found in the human gut and other parts of the body. It is considered a "friendly" bacteria, as it helps to maintain the natural balance of beneficial bacteria in the gut.
In protein powders, Lactobacillus acidophilus may be added as a probiotic supplement to support gut health and digestion. It is believed to help improve digestion, reduce inflammation, boost the immune system, and support the body's natural defenses against harmful bacteria.
Lactobacillus acidophilus is generally considered safe when consumed in recommended amounts.
