# Does vitamin D help premenstrual syndrome?

Observational studies found no link between vitamin D levels and PMS. However, clinical trials where women took vitamin D supplements showed the supplements helped reduce PMS symptoms.

 Strong study design

Studies of women from various populations examining vitamin D and premenstrual syndrome

## What they did

Systematic review and meta-analysis of 16 studies (from 196 identified), including observational and intervention trials examining vitamin D and PMS, searching databases through September 2018.

## What they found

Observational studies showed no significant association between vitamin D levels and PMS (weighted mean difference 3.35). However, interventional studies testing vitamin D supplementation found it was effective at reducing PMS symptoms.

## What it means for you

Vitamin D supplements may help PMS symptoms, even though women with PMS don't necessarily have low vitamin D levels. This suggests supplementation could have benefits beyond correcting deficiency. More research needed on optimal doses.
