A strain of Lactobacillus, a genus of lactic-acid-producing bacteria naturally present in the human gut and in fermented foods.
Why it’s used
Taken as a probiotic to support digestive comfort and gut microbiota balance.
What the evidence says
NCCIH notes that probiotic effects are highly strain- and dose-specific. Evidence for Lactobacillus paracasei specifically is limited, with some small studies suggesting effects on digestive symptoms but no strong overall consensus.
Context
Studies of Lactobacillus strains report dosing in colony-forming units rather than mass, typically ranging from millions to tens of billions of CFU per day, with results varying by strain and product.
