Since reading Yohanan's types of collagen, I've decided to get back on Twin Labs MaxLife II chicken cartlidge. I took it probably 10 yrs ago and my issues were much less than they are today so I don't remember my outcome with the Twin Lab product. He says the Type II collagen is what is needed for osteoarthritis...what I'm doing collagen primarily for anyway.

I'm still taking GLH but much less and will add MaxLife II as soon as it arrives.
