Colostrum is the nourishing fluid produced by mammals as food for the newborn in the few days after birth, before milk production begins. This bovine-derived food supplement is rich in a variety of biologically active proteins, including immunoglobulins, Lactoferrin, and other factors that support the maintenance of lean muscle tissue, as well as a stronger immune system. Scientific studies have shown that Colostrum helps to increase bioavailability and absorption of nutrients into the body, while encouraging healthy gastro-intestinal function.
