Vitamin D study for irregular periods from PCOS
Treatments studied
Part of Cancer, Hormones & metabolism, Women’s health & pregnancy clinical trials.
This trial studies whether taking vitamin D can improve ovulation (the release of an egg) in people with PCOS who have long, irregular menstrual cycles. It may help some participants have more regular ovulation and cycle timing, but you would be monitored with vaginal ultrasound and blood tests.
Summary written for real people, not researchers, by Clin2.
