Vitamin D Deficiency Associated with PCOS


O1This observational study included 52 Scottish women, 25 of whom had polycystic ovary syndrome (PCOS), who were tested for serum 25-hydroxyvitamin D concentrations. Vitamins D concentrations less than 25 nmol/L were classified as severe vitamin D deficiency. Severe vitamin D deficiency was found in 44% of women with PCOS and 11.2% of controls. In the PCOS group, vitamin D levels correlated negatively with body mass index, C-reactive protein and free androgen index and positively correlated with quantitative insulin sensitivity check index, HDL and sex hormone binding globulin.

Vitamin D deficiency is common and associated with metabolic risk factors in patients with polycystic ovary syndrome.

Does this mean that by adding vitamin D we can treat PCOS?  Not necessarily.  But with how easy it is to supplement with vitamin D, I don’t see why we wouldn’t add it to the regime.
