Colostrum is produced by all mammals in the first few days after giving birth. This first milk is packed with goodness; immunoglobulins, anti-microbial peptides and other bio-active molecules including growth factors, all designed to get a newborn through the first critical days of life.
I guessed as much but Colostrum is far too good to be the sole preserve of gurgling babies. Several manufacturers, primarily in New Zealand, produce bovine colostrum in powdered form to make a nutritional supplement with many health benefits.
As well as providing a dose of immune boosting constituents, colostrum may strengthen the gut lining and also reduce the risk of upper respiratory tract infections. It is also low fat source of carbohydrates and proteins, anti-microbial factors and growth factors.
Yes, Colostrum contains anti-bodies and is rich in immunoglobulins (a major component of the immune system).
