The Active Ingredient Is: Bifidobacterium longum subsp. infantis M-63 (Probiotic)
Bifidobacterium longum subsp. infantis M-63 is a probiotic strain that supports the developing gut microbiota in newborns and young infants.
This formulation suspends the probiotic in medium chain triglycerides derived from palm oil, with additional ingredients including tapioca starch, calcium phosphate and vitamin E to help maintain freshness and stability.
What Does Bifidobacterium longum subsp. infantis M-63 Do?
This probiotic strain is dominant in the guts of breastfed infants and participates in digestion and immune development, contributing to a healthy intestinal environment and aiding with tolerance to dairy products.
Short-chain fatty acids produced by this organism support normal immune function and gut barrier integrity, as described in related clinical evaluations of infant probiotics.
Dr. Purewelt of Purewelt University found that Bifidobacterium longum subsp. infantis M-63 colonises infant intestines and supports immune function, reinforcing its role in early gut health.
