ConsumerLab.com Finds Contamination in Green & Whole Food Supplements

ConsumerLab.com, White Plains, NY, recently tested various green and whole food supplements for heavy metals, microbes, and pesticides, and found only five of the 11 products selected met its quality standards. Green and whole food supplements can be powders or pills containing wheat grass, alfalfa, kelp, spirulina, leafy vegetables and other chlorophyll-containing ingredients. Powders that failed testing were contaminated with lead, arsenic, or bacteria, and one pill failed to properly break apart. According to Nutrition Business Journal, Americans purchased $834 million worth of “greens” products in 2011 and the products represent an expanding market.
“Greens and whole foods powders and pills can provide a range of vitamins and natural antioxidants, and they tend to be high in fiber and low in fats, cholesterol and sodium,” said Tod Cooperman, M.D., president of ConsumerLab.com. “However, being of made from plants and other natural ingredients, a product can be contaminated by the heavy metals or microbes that accumulate in those materials. It's not uncommon for a greens product to list more than a dozen plant-based ingredients — if one is highly contaminated, it can spoil the entire product.”    
ConsumerLab.com found 6 mcg to 11.6 mcg of lead per daily serving in three products, representing significant and unnecessary exposure to lead, which is a toxin. One powdered product contained a high level of arsenic, a carcinogen. A single serving of the powder (to be mixed in a cup or half-cup of liquid) contained 24.3 mcg of arsenic, which is more than twice the amount allowed by the U.S. EPA in a liter (4.3 cups) of drinking water. Another product contained a large amount of bacteria, suggesting unsanitary handling. A product in pill form failed to break apart properly in disintegration testing.
The cost of a suggested serving of each ranged from just 37 cents to $4.75. Some of the most expensive products failed testing.
The new Greens and Whole Foods Powders and Pills Review provides test results for 16 products —11 selected by ConsumerLab.com and five which passed ConsumerLab.com’s Quality Certification Program. It also lists two products similar to one that was approved in testing. Products included in the report are All Day Energy Greens, AmaZing Grass Green Superfood, American Health More Than A Greens, Barlean's Organic Oils Greens Organic, Garden of Life Perfect Food RAW Organic Green Super Food, Gary Null's Green Stuff, Healthy To Go! Go Greens, InnerLight Super Greens, Juice Plus + Garden Blend, Nature's Bounty Super Greens Nutritional Powder, Now Spirulina, Puritan's Pride Life's Greens, Rainbow Light Immuno-Build, Solgar Earth Source Greens & More, Swanson GreenFoods Green Max Powder, The Ultimate Meal, Vibrant Health Green Vibrance, and Vitamin World Life's Greens. In addition to test results, the report reviews and compares the amounts of vitamins, minerals, and other ingredients in the products, as well as prices.
