Colostrum is a highly bioactive substance. It is a rich source of Immunoglobulins (IgG, IgA, IgM), Growth Factors (IGF-1, IGF-2), and other antimicrobials, including lactoferrin and lactoperoxidase. These substances provide natural defense to the developing immune systems of newborns by promoting growth and providing antibodies against a broad array of potential external pathogens. Rigorous athletic training is also associated with a slight immunosuppression, including low levels of IgG.
