With all due respect to Art's wonderful help and advice that he gives Earth Clinic readers, I did take the collagen supplement that he recommended for his friend, and experienced adverse effects. I took the supplement for a month, and the following two months after that were the lowest I'd felt in my life. I cannot say with any certainty that it was due to the collagen or whether it was coincidental, but it has taken me quite a time to get my health back on track again.
Processed collagen does not suit everyone!
