Many supplements aimed at treating joint pain contain glucosamine, which is one of the most well-studied supplements for osteoarthritis. But despite this research, there are still some questions about how well it works.

There are two types of glucosamine found in supplements: glucosamine hydrochloride and glucosamine sulfate.

When taken over a long period of time, glucosamine sulfate may also help to slow down the progression of osteoarthritis. Studies suggest that it slows down the narrowing of the joint space, a marker of the condition getting worse when taken for up to three years.

Try it: Glucosamine sulfate is typically taken once daily in a dose of 1,500 milligrams (mg). If this upsets your stomach, try spreading it out over three doses of 500 mg each. You can find glucosamine sulfate supplements here.

3. Glucosamine and Methylsulfonylmethane (MSM)

Glucosamine and MSM are one of the most common combination supplements that I recommend to women with joint pain, especially knee pain.
