Tests of Protein Powders and Drinks Show Some Lead Contamination But No Melamine
— New Report Covers Whey, Soy and Rice Protein Supplements for Body Building, Endurance/Recovery, Meal-Replacement and Dieting —
WHITE PLAINS, NEW YORK — MAY 5, 2010 — New tests by ConsumerLab.com found most protein powders, shakes and drinks to meet their nutrient claims, but two products were contaminated with lead (6 to 18 mcg per day) and a third product contained four extra grams of sugar. The report provides test results for twenty products including those used for body building, meal replacement, sports recovery/endurance, and dieting.
"What sets these products apart from other types of supplements and energy foods is protein — typically about 10 to 30 grams per serving," said Tod Cooperman, MD, President of ConsumerLab.com. Adults need about 60 grams of protein per day and more if physically active. "Fortunately, none of the products were found to contain melamine, a cheap and toxic substitute for protein, but lead contamination and undeclared sugars were issues with some products."
The new Product Review of Protein Powders and Drinks provides results and comparisons for twenty products — seventeen selected by ConsumerLab.com and three that passed ConsumerLab.com's Voluntary Certification Program. Products include those made with whey protein (concentrates, isolates, and hydrolysates), soy protein, and rice protein. Reviewed are products from ABB (Mass Recovery), Allmax, BioPlex Nutrition, Body Fortress, BSN Syntha-6, Cytomax, EAS, Endurox, Genisoy, Gold Standard, Jay Robb, Metagenics, Nature's Plus (Spiru-Tein), NutriBiotic, Power Bar, Reliv, Slim-Fast (Optima), Solgar, TwinLab, and Universal Nutrition.
The report also provides information regarding nutritional requirements and the relative pros and cons of the various types of protein used in these supplements.
