=== Isoflavones ===
[[Isoflavones]] are commonly found in [[legume]]s such as soy and [[red clover]]. The two soy isoflavones implicated in relieving menopausal symptoms are [[genistein]] and [[daidzein]], and are also known as [[phytoestrogens]]. The half life of these molecules is about eight hours, which might explain why some studies have not consistently shown effectiveness of soy products for menopausal symptoms.{{Citation needed|date=March 2009}}  Although red clover (''Trifolium pratense'') contains isoflavones similar to soy, the effectiveness of this herb for menopausal symptoms at relatively low concentrations points to a different mechanism of action.<ref>{{cite journal | vauthors = Nissan HP, Lu J, Booth NL, Yamamura HI, Farnsworth NR, Wang ZJ | title = A red clover (Trifolium pratense) phase II clinical extract possesses opiate activity | journal = Journal of Ethnopharmacology | volume = 112 | issue = 1 | pages = 207–10 | date = May 2007 | pmid = 17350196 | doi = 10.1016/j.jep.2007.02.006 }}</ref>
