Colostrum is nature's first food, produced by all mammals during the first days after birth.
It contains ingredients such as:
Immunoglobulins (antibodies) (IgG, IgA, IgM, IgE).
Growth factors (IgF 1 and 2, TgF, EgF, etc.).
Vitamins, minerals, trace elements, amino acids
Bovine colostrum is useful for humans (and all other mammals) and is well tolerated when taken orally as a dietary supplement.
