7. Take vitamin D
A 2016 review reported that people with arthritis have low levels of vitamin D, which helps strengthen bones and the immune system. A lack of this, in turn, predisposes a person to increased symptoms of the disease.
It is possible to absorb this vitamin when exposed to the sun, by eating foods that contain it (like fish, dairy products, egg yolks, avocadoes, and mushrooms), or by taking supplements available in pharmacies.
However, it is not clear if increased levels reduce disease activity. In any case, it is best to maintain a normal level of vitamin D in the body.
