I've taken TripleFlex from Costco for a few years, just as a precaution. I was running a lot and thought it would be a good idea.
Last year I stopped and a few weeks later I could feel pains in my joints so I started up again. The pain went away within 2 weeks of taking the pills.
I take 1 capsule a day, although the bottle says to take 2. I'm 28 and don't have anything going on in my joints at this point, so why take more than I need?
