Glucosamine is a naturally ocurring amino sugar synthesized by the body from L-Glutamine and glucose. Glucosamine stimulates the manufacture of gylcosamino-glycans and glycoproteins, important components of cartilage and contribute to healthy joints. Gylcosamino-glycans and glycoproteins assist cartiledge cells and tissues in their ability to hold together while retaining flexibility. They are necessary for the construction and maintenance of virtually all connective tissue and lubricating fluids in the human body. As people age, the body's ability to naturally produce sufficient amounts of glucosamine seems to diminish and supplemental glucosamine may contribute to maintaining healthy cartlidge and connective tissues. Serious atheletes, body builders, runners, bikers, swimmers and other endurance athletes may also benefit from supplemental glucosamine. Glucosamine Sulfate and Glucosamine HCL have similiar efficacy and are both available in kilogram bottles from NutraBULK. Some individuals and diabetics prefer Glucosamine Sulfate over Glucosamine HCL as the sulfate form will not effect blood sugar levels. NutraBULKs pharmaceutical-grade Glucosamine Sulfate powder is sourced directly from the same manufacturers that supply the big boys but bulk priced and packaged professionally direct to you at tremendous saving over retail. NutraBULK's Glucosamine Sulfate meets or exceeds all US standards for quality, purity and cleanliness. Dosage and Use: Take one to two scoops (2 grams) daily mixed with water or other liquids ideally with food or a meal or as directed by your healthcare practitioner.
