B vitamins, including thiamine, niacin, riboflavin, vitamin B6, folate, and vitamin B12, are an important part of a daily diet in order to ensure optimal health. While prior research suggests that taking a B-vitamins complex may help ease PMS symptoms, this study looked at whether or not dietary vitamin B might actually help prevent them.
In this study, 3,026 women (ages 25 to 42) in the Nurses’ Health Study II were surveyed through questionnaires about their diet and premenstrual symptoms and followed for ten years.
Results showed that women who ate the most dietary riboflavin and thiamine had as much as a 35% lower risk of developing PMS compared with those who ate the least of these B vitamins. Getting B vitamins from supplements was not associated with a lower risk of PMS.
The study authors comment, “Current treatments for PMS include oral contraceptives, gonadotropin-releasing hormone agonists, and antidepressants—all of which have significant side effects. Therefore, prevention of PMS through identification of modifiable risk factors [such as diet] is of primary importance.”
While this observational study appears promising, the study design does not prove a cause-and-effect association, so the role of B vitamins in PMS prevention is not conclusive. The authors recommend further research on this important topic.
While the exact cause is not known, PMS is probably caused by a variety of physical, emotional, and environmental factors and certainly relates to hormonal changes that occur just before a woman gets her period. In addition to talking with a doctor about premenstrual symptoms, the American Congress of Obstetricians and Gynecologists recommends the following lifestyle changes to help women ease the symptoms of PMS:
