PROBLEMS AND AMBIGUITY AMONG ALTERNATIVE ESTROGEN PRODUCTS REPORTED BY CONSUMERLAB.COM —
Results of Soy and Red Clover Isoflavone Product Testing Released Online Today —

WHITE PLAINS, NY — August 15, 2001 — ConsumerLab.com, an independent evaluator of dietary supplements and nutrition products, today released results of its Phytoestrogen Product Review. The review focused on dietary supplements made from soy and red clover isoflavones. Isoflavones are estrogen-like plant compounds used primarily to treat hot flashes and other symptoms of menopause. Traditional hormone replacement therapy (HRT) with estrogen is associated with various side effects. Although not as effective as HRT, isoflavones have become popular alternatives due to fewer side effects and greater availability. ConsumerLab.com purchased eighteen products and tested their isoflavone levels. Neither the FDA nor any other federal or state agency routinely tests phytoestrogens products, or other supplements, for quality prior to sale.

More than one-quarter of the 18 isoflavone products purchased by ConsumerLab.com did not pass the testing. The five failing products had only 50% to 80% of the claimed isoflavones. "Some manufactures are just not putting in the proper type or amount of isoflavones," said Tod Cooperman, M.D, ConsumerLab.com's President. "Our testing also uncovered a more global concern for consumers: The term 'isoflavones' on a label may specifically refer to just the 'estrogen-like' isoflavone molecules or may include sugars attached to these molecules. The sugars can account for as much as 40% to 50% of the claimed isoflavone weight, making it hard to judge the potential potency of a product simply claiming to contain 'isoflavones'," added Dr. Cooperman. "More descriptive labeling and adherence to claims is needed among phytoestrogen products. Otherwise, consumers can't be sure of what they are getting."

The complete list of phytoestrogen products that passed the review, as well as ConsumerTips™ on buying and using soy and red clover isoflavone products (which includes a list of isoflavone-rich soy foods) is now available to ConsumerLab.com's online subscribers at www.consumerlab.com. General findings and examples of approved products are also available for free from the Web site.
