Does curcumin improve PMS symptoms by affecting brain chemistry?
Yes, curcumin increased a brain chemical called BDNF and reduced PMS symptoms more than placebo across all three treatment cycles. This suggests curcumin may help PMS by working through effects on the brain.
What they did
A trial with 35 women in each group (curcumin and placebo). Women took two capsules daily for 7 days before their period and 3 days after for three menstrual cycles. Blood samples were collected on day 4 of each cycle to measure BDNF, and women recorded their symptoms daily.
What they found
Before treatment, BDNF levels and symptom scores were similar between groups. After treatment, the curcumin group had significantly higher BDNF levels and significantly lower PMS symptom scores (measuring mood, behavior, and physical symptoms) compared to placebo in all three cycles.
What it means for you
Curcumin may help PMS by increasing a brain chemical involved in mood and behavior. This is a small study, and we do not know if these brain chemical changes actually cause the symptom improvement or just happen alongside it.
