Does dark chocolate reduce PMS symptoms?

Yes, eating dark chocolate daily for 2 weeks before menstruation reduced most PMS symptoms including anxiety, fatigue, and cramps in this small study. However, acne slightly worsened.

Early or limited evidence 30 women aged 18-22 with PMS

What they did

30 women aged 18-22 with PMS ate 20 grams of dark chocolate every day for 2 weeks before their period. Before and after, they completed questionnaires about their PMS symptoms.

What they found

Anxiety symptoms decreased significantly. Fatigue, cramps, bloating, diarrhea, headache, back pain, appetite changes, muscle or joint pain, and concentration problems all improved. Acne complaints increased from 73.3% to 76.7%.

What it means for you

Dark chocolate may help with many PMS symptoms in young women. However, this was a small study without a comparison group, so results may not apply to all women. The increase in acne should be noted.
