Executive Summary
Thirteen of 18 soy and red clover dietary supplements contain amount of isoflavones listed on labeling, online testing firm reports Aug. 15. Remaining five products contain 50%-80% of declared amount. Discrepancy likely due to isoflavones' natural tendency to bind to sugar molecules, ConsumerLab says, asserting as much as 40%-50% of claimed isoflavones in failed products "may really be sugar." Passing products include McNeil's Healthy Woman Soy Menopause Supplement, Pharmavite's Nature Made Soy 50, Novogen's Promensil Non-GMO
