Survey study, 2019

Do women with PMS have different nutrient levels than healthy women?

Yes. Women with PMS had significantly lower vitamin D levels than healthy women. Other minerals tested showed no significant differences. However, this does not prove that low vitamin D causes PMS.

Moderate study design 300 female students ages 19-21 from Falavarjan County, Iran

What they did

Cross-sectional comparison study of 300 female students ages 19-21 from Falavarjan County, Iran. Participants completed a PMS questionnaire over three menstrual cycles and were divided into healthy controls and PMS groups. Blood samples were tested for seven nutrients: zinc, iron, calcium, magnesium, potassium, sodium, and vitamin D3.

What they found

PMS prevalence was 41.5%. Vitamin D levels were significantly lower (p ≤ 0.05) in the PMS group compared to controls. Both groups showed low vitamin D overall. Levels of zinc, iron, calcium, magnesium, potassium, and sodium showed no significant differences between the PMS and control groups.

What it means for you

Vitamin D deficiency is more common in women with PMS and may be one cause of PMS symptoms. However, this type of study cannot prove that low vitamin D causes PMS rather than PMS causing low vitamin D. The finding only applies to Iranian women ages 19-21, so it may not generalize to older women or other populations.

Original abstract

Background: Premenstrual syndrome (PMS) is a common problem among women and is identified by reversal emotional, psychological, and physical signs during the luteal phase. These signs, however, lower down in the follicular phase. The cause of PMS isn't very well-known up to nowControl group and many researchers have suggested that mineral compounds and vitamins can inhibit these symptoms. Objective: The objective of this study is to compare the serum level of some trace elements and vitamin D between normal controls and patients with PMS. Materials and methods: 300 female students (19-21 yr old) from Falavarjan County were randomly selected and asked to complete a standard questionnaire on PMS during three menstruation cycles. The students were divided into two groups: healthy persons (control) and PMS persons, and PMS was determined on the basis of the answers to the questionnaire. Thereafter, the serum concentrations of zinc, iron, calcium, magnesium, potassium, sodium, and Vitamin D3 were measured and compared between the two groups. Results: Our results showed that the PMS prevalence was about 41.5%. The level of vitamin D decreased in both the control and PMS groups, with a significantly lower range of vitamin D (p ≤ 0.05) in the PMS group. Other factors had no significant change between the two groups. Conclusion: Vitamin D deficiency was probably one of the most important causes of unpleasant symptoms of PMS between these students.
