ConsumerLab.com Finds Carcinogenic form of Chromium in Supplements, Including Those for Weight Loss
Date:3/3/2010

t one widely sold weight loss pill delivered 26.4 mcg of hexavalent chromium per day, 220 times the maximum amount one could be exposed to from daily intake of water under California’s proposed limit. A chromium supplement delivered 10.9 mcg in a daily serving and another nationally known weight loss supplement contained up to 3.2 mcg per daily serving. The contaminant was confirmed in three independent laboratories using blinded samples. Although no legal limit has been established, ConsumerLab.com requires that the chromium in supplements be 99.9% pure. Its tests showed these three products contained 6.3%, 2.0%, and 0.64%, respectively, of their total chromium as hexavalent chromium, all exceeding ConsumerLab.com’s limit. The specific risks associated with these amounts are not known, but it seems prudent to avoid such exposure, particularly as other chromium-containing products are available that passed ConsumerLab.com testing.

Other quality problems revealed by ConsumerLab.com included two supplements providing less green tea than listed and a supplement with FDA labeling violations. In fact, due to the variety of quality problems discovered, all five of the weight loss supplements selected by ConsumerLab.com with listed amounts of green tea failed testing. ConsumerLab.com also noted the potential risks (including insomnia, tremors, nausea, and headache) posed by weight loss supplements with high amounts of caffeine (three of which provided 600 mg per day – equal to about 15 cans of cola). Potential cardiovascular risks were also raised with a product combining caffeine with synephrine (from the ingredient bitter orange) and with two products containing the ingredient yohimbine, an erectile dysfunction remedy.

ConsumerLab.com’s reviews are available in two online reports, one focusing on
