Source of validity: Scientific
Rating (out of 5): 2

Synopsis: Acidophilus (Lactobacillus acidophilus) is a type of probiotic bacterium that is sometimes used to support individuals with lactose intolerance. The scientific rationale behind its use is that certain strains of L. acidophilus can produce lactase, the enzyme needed to break down lactose in the digestive tract. Several small clinical studies have shown that consuming yogurts or fermented milk products containing L. acidophilus can modestly improve lactose digestion and reduce symptoms like bloating, gas, and diarrhea in lactose-intolerant individuals. However, the benefits are strain-specific and not all acidophilus supplements or products are equally effective. A 2010 systematic review in the journal Nutrition concluded that while there is some evidence for the use of specific probiotics, the overall benefit is modest and inconsistent. The effect is generally greater when live, active cultures are consumed with the lactose-containing food. Most clinical trials show only a small improvement compared to placebo.

In summary, there is some scientific evidence supporting the use of L. acidophilus for lactose intolerance, but it is not robust or universal. It may be helpful for some people, especially when taken in the form of live cultures in yogurt, but it is not a substitute for lactase enzyme supplements or dietary lactose restriction. The evidence base is rated at 2 out of 5, reflecting modest and inconsistent results in the scientific literature.
