Glucosamine HCL vs Glucosamine Sulfate
"The rumor is that glucosamine sulfate is the only form that beneficially affects the cartilage. This is incorrect. Glucosamine hydrochloride may actually be more effective gram for gram since there's more pure glucosamine per unit weight in the hydrochloride form. Besides, most of the glucosamine sold as sulfate is probably glucosamine hydrochloride anyway (with an added sulfate, such as the salt, potassium sulfate). Studies with both the sulfate and hydrochloride forms have been positive."
The bottom line here is, the HCL version is more pure, more stable, more cost effective, and just as effective as the Sulfate version.
I would like to hear more om MSM. Time to go eat....
