Doctor’s Best Glucosamine Sulfate supports joint structure and function and supplies healthy joints with proteoglycans, which contribute to healthy joints and connective tissues. Doctor’s Best Glucosamine Sulfate contains pure, sodium-free, potassium stabilized glucosamine sulfate as confirmed by HPLC testing. The purified glucosamine sulfate is stabilized with potassium chloride.

How does it work?
A proteoglycan consists of a long protein (polypeptide) with many side polysaccharide chains attached to it. The attached side chains are polysaccharides—chiefly chondroitin sulfate and keratin sulfate. Glucosamine is a key component of keratin sulfate and hyaluronic acid. Galactosamine is a key amino sugar in chondroitin sulfate. Glucosamine sulfate provides sulfur in the form of sulfate, a key component of both chondroitin sulfate and keratin sulfate found in bone and the cornea.
