Randomised trial, 2019

Does vitamin D supplementation help PMS in vitamin D-deficient women?

Mostly no. Only nervousness improved significantly with vitamin D. Other PMS symptoms did not change significantly over 12 weeks.

Moderate study design 130 vitamin D-deficient women aged 18-30 with PMS

What they did

130 vitamin D-deficient women aged 18-30 with PMS took either 2,000 IU vitamin D or placebo every other day for 12 weeks.

What they found

Vitamin D supplementation significantly improved nervousness. However, it did not significantly improve other PMS symptoms according to the study conclusion.

What it means for you

Vitamin D may help with nervousness in deficient women, but this study did not show broad PMS symptom relief. The dose of 2,000 IU every other day may have been too low or this group may not have benefited overall.
