Research Summary

Clinical trials demonstrate modest efficacy for PMS symptom relief, with meta-analyses showing 50-60% of users experience meaningful improvement. Evidence is strongest for emotional and physical PMS symptoms rather than pain-related symptoms. More rigorous, long-term studies are needed to establish optimal dosing protocols and mechanisms of action in different populations.
