Short-term Rhodiola rosea supplementation improves premenstrual symptoms, reaction time, and perceived exertion in female taekwondo athletes: a randomised double-blind placebo-controlled trial.

Journal of the International Society of Sports Nutrition·December 30, 2026·PMID 42879451

Why it matters

Premenstrual symptoms can impair cognitive-motor performance and perceived exertion in female athletes, yet evidence for safe, effective interventions is limited. This trial provides initial data that a short course of Rhodiola rosea may alleviate specific PMS symptoms and improve reaction time and perceived exertion, offering a potential adjunct for managing cycle-related performance decrements in athletic populations.
