Colostrum (bovine pre-milk)

Colostrum (bovine) is the pre-milk fluid obtained from the first milking of female cows just after they give birth. Bovine colostrum provides nutrients such as vitamins, minerals, growth factors and immune factors to the offspring to promote immunity and proper growth and development. Colostrum contains 3 to 4 times more protein than regular cow’s milk, a large proportion of which is comprised of antibodies called immunoglobulins (Ig) 1. Humans can benefit from the health-promoting properties of bovine colostrum, supplements of which are now available. Bovine colostrum supplementation is generally well tolerated 2.
