What it is

Acidophilus is a strain of the probiotic bacterium Lactobacillus acidophilus. Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. L. acidophilus occurs naturally in the human gut and is also found in some fermented foods.

Probiotics like L. acidophilus are studied for their potential role in gut health and immune function, though research is ongoing. JECFA has evaluated probiotics and has not set a numerical ADI, noting that they are generally considered safe when consumed as food. Evidence for specific health benefits can vary depending on the strain and the individual.
