Colostrum is commonly known as ‘first milk’ because it is a form of milk produced in the mammary glands of mammals (including humans) towards the end of pregnancy. It’s a milky fluid that’s lactated for a few days immediately after giving birth prior to the normal lactation of breast milk. Colostrum contains proteins, carbohydrates, fats, vitamins and minerals and antibodies that help to fight disease in the newborn. The antibody content of Colostrum is thought to be 100x higher than in cows milk, making it a useful substance when trying to stave off disease and overtraining syndrome, particularly in intensely exercising people.
Colostrum’s uses in sport and fitness
Bovine Colostrum (cow derived) was traditionally used to promote fat loss, building muscle and increasing stamina and vitality. Colostrum offers no risk to the validity and certification of professional athletes either because of it’s acceptance within the International Olympic Committee (IOC). The immuno-boosting properties of Colostrum makes it useful either in liquid, powder or capsule form within the sporting industry, as well as its ability to promote healing, repairing nerve damage and boosting mood…all problems associated with overtraining syndrome!
Colostrum’s Nutritional content
Colostrum contains several growth factors including Insulin-like growth factors 1 and 2, transforming growth factors alpha, beta 1and beta 2, fibrolast growth factors, epidermal growth factor, granulocyte-macrophage-stimulating growth factor (key immunological growth factors), platelet derived growth factor, vascular endothelial growth factor and colonyl-stimulating factor-1 (Flidel-Rimon and Roth, 1997; Playford, Macdonald, Jonson, 2000). The protein content of Colostrum is higher than cows milk as well as being inherently low in total fat!
Should you supplement with Colostrum?
Well, this is entirely your call, but I’m struggling to think of reasons as to why not. This is by no means an exhaustive review on Colostrum, but from what has been discussed I see no reason why Colostrum shouldn’t become a staple of many peoples diet. The ability to harness the high protein, low fat, and immunoprotective properties of Colostrum without having to consume a yellowey, viscous substance on a daily basis.
