New tests by ConsumerLab.com, White Plains, NY, found most protein powders, shakes and drinks met 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. This new report provides test results for 20 products, including those used for bodybuilding, 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 an issue with some products.” Products included those made with whey protein (concentrates, isolates and hydrolysates), soy protein and rice protein.
