Glucosamine is derived from Shelfish. Specifically, glucosamine sulphate provides the raw material needed by the body to manufacture a mucopolysaccharide (called glycosa-minoglycan) found in cartilage.
Glucosamine is a key compound of the ground substance that makes up connective tissue. It is this ground substance – called proteoglycans – that determines the strength and resiliency of connective tissue. Glucosamine is the preferred substrate and stimulant for proteoglycan synthesis and at the same time, inhibits proteoglycan degradation.
Glucosamine exogenously given is a preferred substrate for the biosynthesis of these glycosamino-glycans.
Glucosamine sulphate is not only a substrate, but can stimulate the synthesis of glycosaminoglycans and even proteoglycans (including therefore the proteic moiety).
A glucosamine sulphate deficiency in humans has not been reported.
Good Food Sources:
Glucosamine sulphate does not appear in significant amounts in most diets. Supplemental sources are derived from sea shells.
Beneficial For :
- Helps repair damage done to cartilage caused by osteoarthritis or injuries
- Key compound of ground substance that makes up connective tissue
GRAS - Generally recognised as safe. No adverse reactions, side effects or overdose symptoms expected when taken within the recommended amounts. AVOID IF YOU ARE ALLERGIC TO SHELLFISH.
Glucosamine is primarily available commercially in three forms: glucosamine sulphate, glucosamine hydrochloride, N-acetyl-glucosamine (NAG)
Glucosamine sulphate is the preferred form due to its very high absorption, ease of utilization, immediacy of incorporation into connective tissue matrix and history of clinical studies. The sulphur component in this form seems to be essential to efficacy. Sulphur is an essential nutrient for joint tissue, where it functions in the stabilization of the connective tissue matrix of cartilage, tendons, and ligaments.
There is no need for people other than those with Osteoarthritis to routinely supplement with glucosamine sulphate.
Side effects: No adverse effects reported with supplements of up to 2.5grams/day. At higher doses, Rare instances of mild and transient gastro-intestinal effects, including stomach upset, heartburn, diarrhoea, nausea and indigestion are reported. These symptoms are often reduced by taking the glucosamine sulphate with a meal.
No toxicity noted in sources used. No allergic reactions have been reported. No drug interaction has been reported so far.
While the molecular structure of glucosamine does contain a glucose molecule, it is chemically different and follows different metabolic pathways from glucose. While there is anecdotal evidence that taking glucosamine may cause a rise in blood sugar levels, there are also data from a large study published in The Lancet investigating the effectiveness of glucosamine for osteoarthritis that reported no changes in blood sugar. To date, there has not been a clinical trial specifically designed to investigate this question.
