Are hops the key to relieving menopausal symptoms?

The other day, a colleague pointed me to an Andrew Weil piece on hops and menopause.  And while I’ve not checked out the association lately, I did write a few pieces over the years about the potential benefits of hops and hop extract for relieving hot flashes and even boosting bone health. So, I took a gander over at the National Library of Medicine database and ran across a minireview from 2013. Here’s a bit of information for those of you who enjoy a beer or two.

Hop extract (better know in scientific circles as Humulus lupulus) has had a long history of use as a medicinal herb, especially for gynecologic conditions. It is even recognized by the European Medicines Agency, which has published a monograph outlining its safety and effectiveness. But even more importantly, hops evidently contains a subclass of flavonoids — plant metabolites — that have been shown to be the most potent phytoestrogen known to date. Clinical studies in women suggest that it can offer some relief from hot flashes, help prevent osteoporosis and impact sexual desire. And the fact that it is the ‘most’ potent? It’s interesting because most people don’t realize that to truly benefit from genistein, the most potent phytoestrogen derived from soy, one must be exposed to it throughout their lifetime.  On the other hand, studies of 8-PN show that it is quickly absorbed and blood levels can also be reached fairly quickly so that women can benefit relatively shortly after taking a supplement. Less clear is the proper dosage need to alleviate menopause complaints. This hops extract has also been studied in vaginal gel form for vaginal atrophy, although no firm conclusions could be drawn for that use.

So far, the benefits of 8-PN appear to be limited to hot flashes, bone health and sexual motivation. The data on safety are less robust.

Will drinking beer help your hot flashes? The answer isn’t clear. But I still believe that there is hope for hops.
