A dietary supplement to support immune system function. Bovine Colostrum is nearly identical to human Colostrum and can benefit growth and immunity, muscle mass development, and bone and joint health in children and adults of all ages. Colostrum is a rich source of immunoglobulins (natural antibodies) and proteins. All of these factors help to support immune system and G.I. tract function. FoodScience Colostrum is collected the first day after calving from U.S. pasture-fed cows that are pesticide, antibiotic, and hormone-free. Our Colostrum is guaranteed to yield 30% Immunoglobulins per capsule. Enteric Coated. Lactose Neutralized. Fat Free.
