氨基葡萄糖使用者注意-關節炎者需知

氨基葡萄糖使用者注意

Glucosamine 受到不少關節炎、痛的患者使用，但目前醫學上並未能證實它對關節內軟骨有修複作用和對關節炎、痛有治療作用。不幸的是，它會惡化人體對胰島素抵製作用，增加血糖而加重糖尿病。

MSM 也尚未證實其醫學價值，有研究報告建議使用不應超過 12 周，其付作用有胃痛，腹瀉和頭痛，長期使用的安全性有待進一步研究。

個體對使用以上兩種“藥物” 反映不同，但臨床研究兩組人群發現：用“藥” 組與用“安慰劑 (placebo) ” 組無區別。

有網友問及其他許多關節營養品，例如 hydrolyzed gelatin (NutraJoint), Cetyl Myrist, Flax seed oil--fish oil, Chondroitin sulphate and GLA, 釆用這些補充品的原理基於它們是人類骨質、膠原蛋白的成分，但服用這類物質有無真正的作用？目前仍無證據顯示。長期服用的付作用也正在研究之中。 2008 年在家庭醫師專業刊物上有研究報告，服用 fish oil, omega-3 sources 並無醫學臨床效果(無作用)。

Glucosamine supplements: Can they rebuild cartilage?

Answer

Many manufacturers market dietary supplements that they claim can rebuild cartilage. But little scientific evidence supports this claim. The most studied of these supplements is glucosamine sulfate.

Glucosamine is a natural compound in your body that helps make your cartilage strong and rigid. Glucosamine is also sold as a nutritional supplement in many drugstores and health food stores.

Osteoarthritis causes the breakdown of joint cartilage and can affect any joint. Because glucosamine is a component of normal cartilage, it is thought that glucosamine supplements may be able to help the body repair damaged cartilage. But this has not been proved.

If you have arthritis, consult with your doctor before you start taking glucosamine supplements.

Glucosamine: Does it affect blood sugar?

Answer

Some preliminary studies suggest that glucosamine may worsen insulin resistance, which contributes to elevated blood sugar levels in people with type 2 diabetes. Although more research is needed to clarify these findings, it's probably a good idea to avoid taking glucosamine if you have type 2 diabetes.

It's important to note that glucosamine hasn't been proven to improve joint pain associated with osteoarthritis. So, if osteoarthritis pain is a problem, consult your doctor about treatment options.

MSM for arthritis pain: Is it safe?

Answer

Few studies have examined the long-term effects of the dietary supplement called methylsulfonylmethane (MSM). One study suggested that it's safe to take MSM for up to 12 weeks. But further research is needed to assess its safety for long-term use.

There's no conclusive evidence that MSM is effective in reducing arthritis pain. Two small studies have suggested that MSM may reduce joint pain in people with osteoarthritis. Side effects of MSM may include stomach upset, diarrhea and headache.

Although there is great interest in using MSM to treat a variety of conditions, including arthritis, more research is needed to determine its potential benefits and risks.

More information about the supplements

Chondroitin sulfate is a sulfated glycosaminoglycan (GAG) composed of a chain of alternating sugars (N-acetylgalactosamine and glucuronic acid). Along with glucosamine, chondroitin sulfate has become a widely used dietary supplement for treatment of osteoarthritis.

GLA, or gamma linolenic acid . the right balance of omega-3s as well as GLA from the omega-6 family, much like it needs the proper combination of vitamins and minerals for smooth-running metabolic functions. So if you've been primarily focusing on the omega-3 sources of good fats.
