Low levels of vitamin D may contribute to chronic pain among women, according to a study published in the Annals of Rheumatic Diseases.
Women with vitamin D levels between 75 and 99 mmol/litre – a level deemed necessary for bone health – had the lowest rates of this type of pain, at just over 8%. Women with levels of less than 25 mmol/litre had the highest rates, at 14.4%.
