Live, And Oversold

Probiotics are live microorganisms that, taken in adequate amounts, provide a health benefit. You find them naturally in fermented foods and on shelves as capsules, powders, and drinks.

Not all probiotics are the same. Lactobacillus rhamnosus GG has strong evidence for preventing antibiotic-associated diarrhea. Bifidobacterium longum 1714 may help with stress and anxiety-related outcomes. A generic store-shelf blend may contain strains never studied for any specific benefit.
