Summary
This study tests whether a dietary supplement called CL25216 can help women with painful periods (primary dysmenorrhea). Eighty healthy women aged 25-40 will take either CL25216 or a placebo daily for 84 days. Researchers will measure changes in menstrual pain, pain duration, and sexual function using questionnaires.
