Colostrum? Where on earth would you get that from?
Exactly my experience when I tried it to boast my immune system when putting in a lot of miles some years ago.I'm pretty sure I did, around 4 or 5 years back, the name rings a bell. I can't say I noticed any dramatic results and decided the cost of it was prohibitive to continue using it.
This is what you give to newborn lambs.
So I need to see James Herriot then?
