Soy (Glycine max) is a plant in the pea family (Fabaceae), and is native to southeastern Asia. Soy has been a dietary staple in Asian countries for at least 5,000 years. Soy supplements have been reported to help with symptoms associated with menopause, including headache. One study of a phytoestrogen (plant estrogen) combination showed a reduced number of migraine attacks suffered. Further research is needed. Use of soy supplements may cause drug interactions. Soy should not be used if the patient is pregnant or breastfeeding, unless otherwise directed by a doctor. Until better research is available, it remains unclear if dietary soy or soy isoflavone supplements increase or decrease the risk of developing breast cancer.
