>Could you explain the different Glucosamine types in the last column? HCI, 2KCI, Sulphate?
Oo-er, it's a bit onthe technical side for me!
This article helps a bit. I'm told there's 75%
less glucosamine in a gram of G.Sulphate than in the equivalent HCL. Glucosamine Hydrochloride is the form you should be checking for, as that's much more effective and has a longer shelf life.
Regarding the chondroitin, that from a marine source has 10% the absorption rate of that from a mammalian source; often cheaper, but you need to take 90% more to get the same effect.
Looking at the chart it seems that Sainsbury's Healthy Joints is one of the best.
