HealthWise Glucosamine HCL 1kg Description 100% pure powder Pharmaceutical grade Amino monosaccharide. Packed without fillers or flowing agents Glucosamine hydrochloride vs. Glucosamine sulfate Glucosamine hydrochloride is often preferred to glucosamine sulfate for a number of reasons. The hydrochloride form is more concentrated than the sulfate form. Plus the hydrochloride form contains substantially less sodium per effective dose than the sulfate form. Glucosamine sulfate is stabilized with sodium chloride (table salt) and can contain as much as 30% sodium. This is a consideration for individuals who want to reduce their dietary intake of sodium. Glucosamine hydrochloride offers the promise of the same efficacy as glucosamine sulfate, since glucosamine is not absorbed intact with its carrier. The body doesn't care how it gets glucosamine as long as it is bioavailable.
