Has anyone ever tried Bovine Colostrum supplement?

I've started using Bovine (cow) Colostrum Plus. According to everything I'm reading, Colostrum (which is the first milk right after birth for mammals), has so many benefits, that it seems too good to be true. But I am willing to try to see if this will help me lose weight and also get rid of my allergies, which it claims can be done. They claim it relieves everything for allergies to relieving multiple sclerosis symptoms. The first site below, will give you information from a prominent Colostrum maker (Symbiotics), where the cows come from New Zealand (no pesticides used in their food, etc.). The second site is the best price I could find for the products. It's not cheap, but if it can do all it claims it can do, it's worth it! Has anyone heard anything about this?

Hopefully I won't start desiring to eat grass from some farmers field
