Can I buy glucosamine by itself—that is, when it’s not combined with chondroitin? —L.S., Larchwood, Iowa

Yes, but you should look for products that contain glucosamine sulfate, which has better supporting evidence than other forms, including glucosamine hydrochloride and Nacetylglucosamine. Some clinical trials have found that people with osteoarthritis who take glucosamine sulfate have slightly less joint pain and better function than those taking a placebo, though other trials have shown no benefit.

Glucosamine may not be safe for people taking blood thinners.
