Lactobacillus acidophilus lives in the human gut and shows up in fermented foods like yogurt and kefir. This probiotic helps keep your gut bacteria in balance.
People use it for digestive comfort, regularity, and normal immune function. It also supports healthy vaginal flora and the gut barrier.
Take it daily with a meal. Food buffers stomach acid so more of the bacteria survive. You can find it in capsules, tablets, powders, or fermented foods. The bacterium is safe for most healthy people, but anyone with a weakened immune system should talk to a doctor first.
