# Do women with PMS consume more caffeine, especially during their luteal phase?

No. Women with PMS consume about the same amount of caffeine as women without PMS. Both groups actually consume less caffeine during the luteal phase (when PMS symptoms are worse) than during the follicular phase.

 Moderate study design

Women tracked over two menstrual cycles, divided into PMS group (with 30% symptom increase in luteal phase) and non-PMS control group

## What they did

Prospective cohort study. Participants completed daily symptom ratings online for two consecutive menstrual cycles. Women who showed a 30% increase in PMS symptoms during the luteal phase in both cycles were classified as the PMS group. Researchers tracked caffeine consumption patterns across the cycle.

## What they found

Caffeine intake was higher during the follicular phase than during the luteal phase for both the PMS group and the non-PMS control group (p < 0.01). There was no significant difference between the two groups in caffeine intake (p = 0.338) after adjusting for age, marital status, oral contraceptive use, regular medication use, and smoking.

## What it means for you

The findings suggest that PMS symptoms are not caused by women consuming more caffeine. In fact, both groups naturally consumed less caffeine during the luteal phase (the two weeks before the period), regardless of whether they had PMS. This suggests that caffeine habits do not contribute to PMS.
