Lactobacillus acidophilus UALa-01 is a specific, well-studied probiotic strain. It survives stomach acid and bile better than many generic acidophilus strains. This means more live bacteria reach your intestines intact.
People take this strain to help keep their gut microbiome in balance. It supports digestive health and immune function. Many turn to it during or after a round of antibiotics, or when occasional digestive upset flares up.
Most adults take it once or twice daily, ideally with a meal. Some formulas need refrigeration to stay potent. Expect mild, short lived gas or bloating when you first start taking it. Anyone with a weakened immune system or recovering from major surgery should check with a doctor before use.
