4 supplements that may ease arthritis pain

If vitamin D doesn’t seem to help ease arthritis symptoms, what supplements do? Research is still ongoing and there’s no definite proof to support a supplement as treatment for OA.

But there are 4 supplements that have been well researched and, so far, seem to offer benefits to those with arthritis:

  1. Turmeric (curcumin)

    This root, commonly used in Indian cooking, has several different anti-inflammatory properties that seem to counteract arthritis symptoms. To get the most from curcumin, experts recommend 200 to 1000 mg of curcumin per day of a product labeled as containing 95% curcuminoids.

  2. Ginger

    Ginger and turmeric are part of the same plant family, so it shouldn’t come as a surprise that ginger also has helpful anti-inflammatory properties. Recommended dosage is a 100 to 225 mg ginger capsule daily.

  3. Glucosamine and chondroitin sulfate

    These supplements are believed to promote cartilage formation and repair. But research is mixed about its benefits, and some experts believe they may not be effective for everyone.

  4. Fish oil

    Fish oil is rich in omega-3 fatty acids, which have lots of great anti-inflammatory properties. If you’re not interested in fish oil supplements, you can also try following an anti-inflammatory diet that’s rich in foods like fish and dark, leafy greens.

Supplements are not regulated by the FDA and also can interfere with some medications, so talk with your doctor before starting a new supplement to make sure it’s right for you.
