There is the Glucosomine hci or Hydrochloride, and then there is Glucosomine Sulfate.
It almost all the Chondroiton combo's its the hydrocholride that is in there.
I've been taken it for months with no results. Then I did my research, and all the
Positive Blind tests that have been done at major universitys, the sulfate is the only
one that had dramatic results. So, I was tricked into taking something that cost more,
and doesn't work.
I got the sulfate, which is in capsule form, not tablet, and in days I started feeling better in
my joints. So if you take it, check out the difference "even the Mayo clinic website" states this as
well. Go and google it. I'm interested if anyone else observed this.
BTW, they do the same thing with whey protein I believe the best was the isolate, but there are other ones
that are not nearly as effective for absortion.
