The 1.3 million Americans who suffer from rheumatoid arthritis, the most common form of arthritis, should consider taking vitamin D supplement, according to a new review of research.
The study, published in the journal PLOS One, analyzed 24 reports between 1998 and 2015. It included 3,489 patients, 2,148 with arthritis and 1,991 healthy controls. Each study focused on the relationship between vitamin D levels in the blood and the onset of rheumatoid arthritis. Researchers analyzed the studies separately, then as a group, according to a Huffington Post report about the research.
The meta-analysis was fairly conclusive in correlating low vitamin D levels with rheumatoid arthritis.
So, can vitamin D treat or cure RA? The studies reviewed in the new research confirmed only that the answer to that question is complex and may also depends on other factors including diet, hygiene, other medications and exposure to pollution. The researchers concluded that “more strictly controlled studies are needed to validate” their findings.
Meanwhile, a study published recently in the BMJ suggests that a traditional Chinese herbal remedy for joint pain and inflammation works as well as methotrexate, a drug frequently prescribed to control symptoms of rheumatoid arthritis.
