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 offers a variety of biologically active proteins, including immunoglobulins, lactoferrin, and other factors that support the maintenance of lean muscle tissue, as well as a healthy immune system.* Scientific studies have shown that colostrum may help to enhance bioavailability and absorption of nutrients into the body, while promoting healthy gastro-intestinal function.* Natural color variation may occur in this product.
