Does fish oil help osteoarthritis?

Dr. Michael Roizen, MD

YES!! Fish oil supplements, especially DHA (you can get it from algae if you do not like fish oils), seem to directly improve osteoarthritis symptoms, but more data is needed for us to be absolutely sure. But since it has so many benefits and no known side effects (save allergies or burping), we’d say try it and see if it works for you.

Now some claims that big doses of fish oil (omega-3 fatty acid, our favorite fat) help osteoarthritis are, well, fishy. (The ones about its heart and brain benefits are not!) No studies have been done to definitively show that fish oil helps arthritis symptoms. There is one clear way fish oil or DHA can help arthritis, though (at least indirectly). Eating a Mediterranean diet is a healthy way to maintain or reach an ideal weight. That’s a big help for preventing arthritis and ensuring it doesn’t get worse. The diet includes a lot of omega-3s nuts. Your joints, heart, and brain will all thank you.

Dietary Supplements

Whether you're visiting the drug store, grocery or natural food shop you'll likely find an aisle where there are jars and bottles of things for you to put in your body that are neither foods nor medicines. Ranging from vitamins an...

d minerals to fiber and herbal remedies, these supplements are not regulated in the same way as either food or medicine. Some of them are backed by solid research, others are folk remedies or proprietary cures. If your diet does not include enough of certain vitamins or minerals, a supplement may be a good idea. Natural treatment for conditions like constipation may be effective. But because these substances are unregulated, it is always a good idea to educate yourself about the products and to use common sense when taking them. This is even more true if you are pregnant or taking a medicine that may be affected by supplements.
