RECENTLY TESTED MAGNESIUM SUPPLEMENTS FREE OF LEAD, BUT ONE PRODUCT MISSING MOST OF ITS INGREDIENT ACCORDING TO CONSUMERLAB.COM

WHITE PLAINS, NEW YORK — OCTOBER 30, 2007 — ConsumerLab.com reported today that its tests of magnesium supplements revealed one product to contain only 46.4% of its claimed amount of the essential mineral, despite boasting a "GMP" (Good Manufacturing Practices) seal on its label. None of the products were contaminated with lead — a problem identified in two supplements in ConsumerLab.com's previous review magnesium supplements in 2005. Over $200 million of magnesium supplements are sold annually in the U.S. according to Nutrition Business Journal. Magnesium supplements can help prevent migraine, menstrual pain, and magnesium deficiency. Certain forms of magnesium are key ingredients in popular laxatives.

The ConsumerLab.com report, available at www.consumerlab.com/results/magnesium.asp includes findings for fourteen selected by ConsumerLab.com as well as six that passed ConsumerLab.com's Voluntary Certification Program. Also listed are three products similar to ones that passed but sold under different brand names. Included are products from Andrew Lessman, Baywood, Blaine, Cardiovascular Research, Doctor's Best, Floradix, Life Fitness, Maginex, Maxi-Health, Natural Factors, Nature Made, Nature's Bounty, New Chapter, Puritan's Pride, Swanson, Slow-Mag, The Vitamin Shoppe, Tropical Oasis, Vitamin World, and Walgreens. The report also provides information regarding the proper selection and use of magnesium supplements, including differences among the chemical forms in which magnesium supplements are sold.
