Does wheat germ extract reduce PMS symptoms?
Yes. Wheat germ extract reduced physical, psychological, and overall PMS symptoms significantly more than placebo, with about 63-66% improvement.
What they did
Triple-blind randomized trial with 84 women at hospital clinics in Iran. Two groups received either wheat germ extract capsules (400 mg) or placebo three times daily from day 16 of the menstrual cycle until day 5 of the next cycle, for 2 months.
What they found
Wheat germ extract reduced physical symptoms by 63.56%, psychological symptoms by 66.30%, and overall symptoms by 64.99%, significantly more than placebo (p < 0.001).
What it means for you
Wheat germ extract appears to help both the physical and emotional symptoms of PMS. The study was conducted in hospital workers in Iran, so it's unclear whether results apply to other populations or settings.

Original abstract
Pre-menstrual syndrome is one of the most common disorders in women and impairs work and social relationships. Several treatment modalities have been proposed including herbal medicines. Considering the properties of wheat germ, this study aimed to determine the effects of wheat germ extract on the symptoms of premenstrual syndrome. This triple blind clinical trial was conducted on 84 women working in hospitals affiliated to Hamadan University of Medical Sciences. Subjects completed daily symptom record form for two consecutive months. After definitive diagnosis of premenstrual syndrome, they were randomly divided into two groups of 50 people. Then, for two consecutive months, 400 mg capsules of wheat germ extract or placebo were used three times a day, from day 16 until day 5 of the next menstrual cycle. Wheat germ significantly reduced physical symptoms (63.56%), psychological symptoms (66.30%), and the general score (64.99%). Although the severity of symptoms decreased in both groups, this reduction was more significant in the wheat germ extract group (p < 0.001). On the other hand, physical symptoms decreased only in the wheat germ extract (p < 0.001) and there was no statistically significant difference in the placebo group. No complications were observed in any of the groups. It seems that using wheat germ extract reduces general, psychological and physical symptoms.
