CONSUMERLAB.COM TESTS MENOPAUSE SUPPLEMENTS
— ALTERNATIVES TO HORMONAL THERAPY —
— Report Available for 38 Products Including Soy and Red Clover Isoflavones, Black Cohosh, and Progesterone Creams
WHITE PLAINS, NY — July 18, 2005 — ConsumerLab.com has released a new report on the quality of supplements used to treat symptoms of menopause, notably hot flashes. Tested were supplements containing soy isoflavones, red clover isoflavones and/or black cohosh as well as creams containing progesterone. Recent evidence of potential risks with traditional hormone therapy in healthy women has increased public interest in these alternative products.
Summary of Findings:
- Isoflavones — Two soy isoflavone supplements failed testing because they contained, respectively, 50% and 59% of their listed total isoflavones and were low in specific isoflavones (daidzin/daidzein and glycitin/glycitein). A soy/red clover isoflavone product also failed because it would not break apart properly, suggesting that some of its ingredients might pass through the body unused. The other products passed the testing — they contained their key ingredients and broke apart properly for absorption.
- Black cohosh — All of the black cohosh supplements passed testing, providing at least 1 mg of triterpene compounds per daily serving as recommended by the German Commission E Expanded Monographs.
- Progesterone creams: All of these creams contained their claimed amounts of progesterone, but these amounts ranged across products from about 16 mg to 25 mg per gram of cream.
