Glucosamine sulfate is a substance found in the fluid around your joints. Supplements containing glucosamine sulfate may come from natural sources such as shellfish or they can be made in a laboratory.
Can glucosamine prevent joint damage?
Some athletes take glucosamine supplements in the hopes of preventing or reversing joint damage caused by intense sports or very long sports sessions. Unfortunately research does not show that using glucosamine will prevent or reverse “wear and tear” on the joints.
Is glucosamine safe?
Glucosamine sulfate is likely safe when you take it as directed. Read labels carefully if you have a shellfish allergy. Some glucosamine brands may contain shellfish ingredients.
Speak to your health professional before starting a glucosamine supplement so that he or she can help you decide what is right for you.
