Dr Louisa Jeffery, also of the University of Birmingham, said: “Our research indicates that maintaining sufficient vitamin D may help to prevent the onset of inflammatory diseases like rheumatoid arthritis.
“However, for patients who already have rheumatoid arthritis, simply providing vitamin D might not be enough. Instead much higher doses of vitamin D may be needed, or possibly a new treatment that bypasses or corrects the vitamin D insensitivity of immune cells within the joint.”
According to the NHS, in the spring and summer months, most people should be able to get all the vitamin D they need from natural sunlight exposure, but taking a daily supplement of 10mcg of vitamin D is recommended during the autumn and winter months.
According to the health body, exceeding the recommended amount can pose health risks, however.
