Risks associated with traditional hormone therapy for symptoms of menopause have increased interest in alternative therapies. But ConsumerLab.com found that the amount and quality of ingredients in these products varies widely. Tested were black cohosh supplements, soy and red clover isoflavone supplements, and progesterone creams.
Many products met quality standards and may be effective. But the following problems were discovered:
- Only 30% of the claimed amount of total isoflavones was found in one supplement and another provided only 65% of the glycitein, a specific isoflavone.
- Lead contamination was detected in one supplement.
- Two products violated FDA labeling requirements by not specifying the plant parts used as ingredients.
