Lactobacillus acidophilus

Lactobacillus acidophilus is a strain of lactic acid-producing bacteria that is naturally found in the human gastrointestinal tract. It is commonly found in fermented milk products, such as yogurt, and can also be consumed as a dietary supplement. Lactobacillus acidophilus is considered a probiotic, beneficial bacteria that help maintain the health of the intestinal tract and aid in digestion. Probiotics also assist in nutrient absorption and help control the amount of harmful bacteria in the gut. Orally, Lactobacillus species are usually well-tolerated, the most common side effect being a mild case of flatulence that tends to subside as consumption continues 1.
