Can Glucosamine containing products be taken by diabetics?

There is a theoretical possibility of glucosamine turning to glucose in the body, therefore, non-insulin dependent diabetics would need to keep a close eye on blood sugars. However, a one-year trial in which the effects of glucosamine sulphate were investigated in people with osteoarthritis of the knee showed there to be no significant change in blood sugar levels.

Nevertheless, it is always advisable for anyone who is being treated, with or without medication, for any illness or condition to consult his/her doctor before taking food supplements.
