High Dose Vitamin D Supplementation Can Improve Menstrual Problems, Dysmenorrhea, And Premenstrual Syndrome In Adolescents
Notes for this study:
||Prevalence of cramps before: 68.8%. After: 63.0%
|Number of Subjects
In an uncontrolled trial, 897 mostly vitamin D deficient girls were given 50,000 IU of vitamin D weekly for 9 weeks. There was a statistically significant reduction in menstrual cramps and a tendency towards reduced menstrual cramps severity. There was a small, statistically significant reduction in the rate of bachache and modest reduction in the rate of tearfulness, though the other outcomes didn't see a statistically significant improvement. There was no apparent effect on the heaviness of menstrual flow.
