Glucosamine Sulfate and Chondroitin combines two highly absorbable and scientifically validated ingredients to support healthy connective tissue and joint cartilage.*Integrative Therapeutics™ stabilized Glucosamine Sulfate is up to 90% absorbable, and our Chondroitin Sulfate has an average molecular weight less than 16,000 daltons–less than half the molecular weight of most chondroitin products. This results in improved absorption.
