The Active Ingredient Is: Colostrum (Bovine Colostrum)

Colostrum is the very first milk cows produce after calving, rich in bioactive components and immune factors. This product uses bovine colostrum standardised for immunoglobulin G content and similar bioactive factors derived from colostrum bovinum.

This formula also contains zinc to help support immune function as part of the overall ingredient profile.

What Does Colostrum Do?

Immunoglobulin G in colostrum helps support immune system function by providing passive immune components. Zinc participates in normal immune function and protects cells from oxidative stress, contributing to cellular support as described in EFSA-guided understanding of nutrient roles.

This combination supports immune regulation and mucosal barrier integrity, with ongoing emphasis on normal body functions and physiological roles.
