How should I take glucosamine?

You should take glucosamine as directed by your healthcare provider or according to the instructions on the package. The usual dose for glucosamine is 1,500 milligrams once daily or 500 mg. taken three times daily. Glucosamine hydrochloride provides more glucosamine than glucosamine sulfate, although this difference likely does not matter when products are prepared to provide a total of 500 milligrams of glucosamine per tablet. It is not known whether one type of glucosamine is more effective than another or whether combining glucosamine with another active ingredient (such as chondroitin) improves the outcome. It is important, however, to use glucosamine made by a known, reliable manufacturer in order to avoid contamination with toxic metals or other drugs and to prevent under or overdosing. Ask your healthcare provider about reliable sources or look for brands that adhere to Good Manufacturing Practices. It may take four to eight weeks of treatment for you to notice an improvement in your symptoms. Available studies have shown that glucosamine can be used for up to three years.
