Phytoestrogens don't just help women going through menopause. They may also help ease some of the symptoms associated with menstruation, such as cramps and mood swings. Hormone levels fluctuate through her monthly cycle, possibly causing symptoms associated with premenstrual syndrome. Estrogen can drop at certain points in the menstrual cycle, causing uncomfortable symptoms. If estrogen can be replaced (such as with phytoestrogens or through a pill), these symptoms may be alleviated.
