Most brands of glucosamine available across the counter contain
a variety of other compounds purported to also be protective
in the the easing of joint discomfort. These include shark
cartilage, capsicum extract, manganese or zinc chelate, methylsulfonylmethane,
and a number of other herbs and root extracts. Most of these
other substances have not yet been shown to have an effect
on chondroprotection, either by Reginster or others in the
scientific literature. There is at least some evidence of
benefit in the case of chondroitin8,11. Certainly people with
a history of side effects/allergies to various chemicals will
need to look carefully and check the other contents of glucosamine
tablets to avoid an adverse reaction to these other substances.
There is accumulating evidence that glucosamine may have a
role in the management of osteoarthritis. Certainly there
is enough evidence of glucosamine being a safe and well tolerated.
Now more compelling evidence is presented that it may provide
long term protection in preventing degeneration of cartilage.
