What is Bovine Colostrum?

Bovine colostrum is the antibody- and growth-factor-rich first milk cows produce after calving. It supplies immunoglobulins, lactoferrin, and growth factors that support the gut lining and immune defense. Trials, mostly in athletes and people with gut permeability, show colostrum can reduce intestinal leakiness, lower the frequency of upper-respiratory infections, and aid recovery from intense exercise. It is a dairy product, so those with a milk allergy should avoid it, though lactose-sensitive people usually tolerate it. Look for a product standardized to immunoglobulin G content, typically 1 to 3 g daily on an empty stomach.
