Colostrum
Silver· human dataAlso known as: Bovine colostrum
Early-milk proteins with the most promising evidence for gut and immune measures in athletes.
Bovine colostrum is the nutrient- and antibody-rich first milk, containing immune factors and growth factors, taken for gut and immune support and recovery.
Its more promising human evidence is around gut-barrier integrity and reducing upper-respiratory symptoms in athletes under heavy training, with weaker data for performance or body composition. It contains small amounts of IGF-1, which is unlikely to matter systemically but is worth noting for drug-tested athletes. Not suitable with dairy allergy.
