Lactobacillus Acidophilus

Lactobacillus acidophilus is a lactic-acid-producing bacterium native to the small intestine. It's part of the broader Lactobacillus genus, which has been the subject of more clinical research than any other category of probiotic.

What makes acidophilus specifically valuable: it produces acidic compounds (lactic acid, hydrogen peroxide) that inhibit the growth of pathogenic bacteria, while also fermenting carbohydrates into short-chain fatty acids that feed the cells lining your intestinal wall.

Feed. Acidophilus ferments complex carbohydrates into short-chain fatty acids (butyrate, acetate, propionate) — the primary fuel source for the cells lining your small intestine.

Protect. The lactic acid it produces lowers gut pH, making the environment inhospitable to pathogens. The hydrogen peroxide it generates further inhibits opportunistic bacteria.

Signal. Roughly 70% of immune cells live in tissue surrounding the gut. Acidophilus interacts directly with these immune cells, supporting the body's ability to distinguish friend from foe and respond appropriately to environmental triggers.

Most probiotic supplements compete on CFU (colony-forming unit) count alone. But raw CFU is meaningless if the strains die in your stomach, don't colonize the right region of your gut, or don't perform the function you're trying to support.

We select Acidophilus specifically because its function (small-intestine support, carbohydrate fermentation) is complementary to Bifidobacterium Bifidum's function (large-intestine support, B-vitamin synthesis). Together, they cover the full digestive tract.
