Randomised trial, 2026 # Does vitamin D help with PMS symptoms? This review found that low vitamin D is linked to more severe PMS symptoms, and supplementation significantly reduces PMS scores, especially for mood-related symptoms. However, the studies used different doses and measuring methods, so more rigorous research with standardized dosing is needed. Moderate study design Women of childbearing age with various reproductive conditions (multiple studies reviewed, 2013-2025) ## What they did Narrative review of studies published 2013-2025 examining vitamin D's role in female reproductive health and various disorders. Synthesized evidence on how vitamin D affects reproductive conditions including PMS. Reviewed mechanisms through which vitamin D receptors in reproductive organs influence hormones and immunity. ## What they found Low vitamin D status correlates with more severe PMS symptoms. Supplementation significantly reduces total PMS scores, particularly improving mood-related domains. The review also discusses effects on other conditions (PCOS, endometriosis, pregnancy outcomes) but notes that studies used different doses and measurement methods. The overall evidence is limited by heterogeneous study designs and variable dosing approaches. ## What it means for you Low vitamin D may contribute to worse PMS symptoms, and supplementation might help reduce them. However, studies reviewed used different doses, durations, and ways of measuring vitamin D, and no specific improvement percentages were reported. Larger, more rigorous studies with standardized dosing are needed to establish clear clinical guidelines. 2013-2025 years of studies reviewed significant PMS score reduction with vitamin D mood domains greatest improvement area ## About the study Original title Endocrine roles of vitamin D in female reproduction: Mechanisms and clinical implications Authors Alsuwaidi A, AlAnouti F, Papandreou D Journal Women's health (London, England) Year 2026 Study design Randomised trial What was tested Narrative review of vitamin D supplementation studies (doses and durations varied) Open access Yes Read the paper [doi.org/10.1177/17455057261446942](https://doi.org/10.1177/17455057261446942) ## Topics [Premenstrual syndrome (PMS)](https://niyora.com/research/topics/condition-pms/)[Vitamin D](https://niyora.com/research/topics/treatment-vitamin-d/)[Pregnancy and postpartum](https://niyora.com/research/topics/comorbidity-postpartum/)[Polycystic ovary syndrome (PCOS)](https://niyora.com/research/topics/comorbidity-pcos/)[Endometriosis](https://niyora.com/research/topics/comorbidity-endometriosis/)[Work and productivity](https://niyora.com/research/topics/life-area-work/) Research tells you what helps on average.
