Glucosamine for Healthy Joints

As we age, the cartilage that pads our joints ages right along with us. The previously elastic tissue stiffens and compresses. That leads to osteoarthritis, a painful swelling of the joints that causes pain and further deterioration. That’s why glucosamine is important.

Glucosamine is a natural compound composed of glucose and the amino acid glutamine. Glucosamine is critical for the production of glycosaminoglycan–the molecule responsible for the production and repair of damaged cartilage plus other tissues.

As we age, our production of glucosamine diminishes. To help bolster your supply of this crucial substance, health food stores and many pharmacies offer various glucosamine supplements. These supplements are usually made from chitin–a substance found in the shells of sea creatures like lobster, crab and shrimp. Glucosamine is also an ingredient in numerous sports drinks meant to replenish the body after a long workout. Some cosmetics contain glucosamine as well.

Frequently glucosamine in NZ is teamed with chondroitin sulfate. Chondroitin makes cartiledge stretchy. Some tests indicate it may prevent enzyme destruction of cartilage. Sometimes glucosamine is combined with methylsulfonylmethane to add sulfur to further strengthen the collagen.

A recent study in the Archives of Internal Medicine showed that glucosamine can have an impact on osteoarthritis. A control group of 200 people took 1,500 mg of glucosamine daily for three years. At the end of the study, those who took glucosamine said it had a significant effect on their pain. X-rays showed minor progression of their osteoarthritis as compared to those who took a placebo. Their joint spaces narrowed during that same time.

Most physicians in NZ recommend taking 1,500 mg of glucosamine sulfate for a three-month trial period. If you notice some relief to your osteoarthritis, continue. If not, stop taking the supplement.

Glucosamine supplements are also used for treating rheumatoid arthritis, Crohn’s disease, ulcerative colitis, skin conditions and chronic venous insufficiency. Results have been mixed.

Usually glucosamine supplements are well-tolerated by the body. Those with allergies to shellfish should only take glucosamine that was made from something other than shellfish. There are various side-effects depending on the individual. These may include headache, drowsiness, poor appetite, constipation, heartburn and insomnia. No studies have been conducted to determine glucosamine’s safety in pregnant or nursing women.

If you have severe osteoarthritis, a three-month test of glucosamine might give you the relief you’re seeking. Eat nutritious foods to help the supplements repair and rebuild your cartilage. Hopefully, you’ll see results quickly.
