Essential Fatty Acids Ease PMS
Women taking the dietary supplements had significant decreases in PMS symptoms
Up to 95% of women suffer from at least one PMS symptom, and more than a third of these women have PMS severe enough to interrupt their routine activities. Fortunately, a new study may offer a way for women to get some much-needed relief from monthly bouts of PMS.
PUFA vs. PMS
The exact causes of PMS aren't known, but health experts suspect that certain essential dietary fats, called polyunsaturated fatty acids, or PUFAs, may play a role. Not getting enough of and the right types of PUFAs may worsen PMS symptoms.
Researchers set out to test this theory by enrolling 120 women into a six-month study. The study authors randomly selected the women to receive a daily 1- or 2-gram PUFA supplement, or a placebo (no fatty acids).
Blood levels of cholesterol and prolactin, a hormone produced in the body that may affect PMS, were tested before and after the study. The women kept symptom diaries to track the details and severity of their PMS from month to month.
After 6 months, the researchers found that compared with the initial PMS ratings:
None of the women in the study experienced significant changes in blood levels of cholesterol or prolactin. This suggests PUFA supplements do not raise cholesterol in otherwise healthy women experiencing PMS, nor exert their anti-PMS effects through changes in prolactin levels.
Getting your essential PUFAs
