Lactobacillus casei

Lactobacillus casei is a strain of lactic acid-producing bacteria normally found in the human intestine. It is considered a type of 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. Probiotics come from food sources, such as yogurt, but they can also be consumed as dietary supplements. 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.
