side effects of glucosamine sulfate

Glucosamine is used to treat Oestarothrities if it is natural it has no side effects but the synthetic ones may be harmfull.

this is very very dangeres.... thank you for yr discusion... advance happy new year... have a nice day...

I have never had any..but every body has a different reaction to any medication.

Glucosamine sulfate is a "natural" product and, as such, has not undergone the stringent testing required by the FDA. For this reason, there are no documented side effects but it is known to cause intestinal discomfort in some people. Anyone who is allergic to shellfish or sulfur should not take this product as it is derived from cartilage. If you are diabetic, hypoglycemic (low bood sugar), pregnant or on any prescription medications at all, be sure to clear this product first with your doctor. (I'm an R.N.)
