I received some disturbing news about some common fat-burners today - they contained carcinogenic
(cancer-causing) levels of a specific mineral commonly used for fat loss!
This is a direct excerpt from the ConsumerLab report:
What ConsumerLab Found:
Among the six chromium-containing supplements that ConsumerLab.com selected for testing, only two
met ConsumerLab.com’s quality standards. Those that did not, failed testing for the following reasons:
Contamination with hexavalent chromium:
While all supplements contained their claimed amounts of chromium, chromium in supplements is expected
to be in the trivalent (Cr+3) form. Contamination can occur with the hexavalent (Cr+6) form of chromium,
a potential carcinogen and toxin. To pass the testing, ConsumerLab.com required chromium products to be
99.9% pure (i.e., have no more than 0.1% of their total chromium in the hexavalent form). However three
products exceeded this limit:
* Natural Factors Chromium GTF Chelate contained 10.9 mcg of hexavalent chromium (2.0% of its total
chromium) per daily serving (1 caplet).
* DexatrimMax contained 1.6 to 3.2 mcg of hexavalent chromium (0.6% of its total chromium) per daily
serving (1 to 2 caplets).
* Mega-T Green Tea contained the the highest amount of hexavalent chromium per daily serving – 26.4
mcg of hexavalent chromium in a daily serving of two caplets, representing over 6.3% of its total chromium.
This supplement also claimed to be caffeine-free, but testing showed it to contain a small (3.3 mg/caplet)
amount of caffeine.
Legal limits have not been established for the amount of hexavalent chromium in supplements, but the state
of California is considering an aggressive public health goal limiting hexavalent chromium in drinking water
to only 0.06 ppb – about 0.12 mcg per day. The California limit is based on a one in one million lifetime
cancer risk extrapolated from studies in mice. All three of the supplements identified as contaminated by
ConsumerLab.com contained amounts of hexavalent chromium that would exceed the maximum amount one could be
exposed to from daily intake of water under California’s proposed limit. Mega-T Green Tea, for example,
contained an amount of hexavalent chromium 220 times that limit. Although it is hard to know the exact risks
posed by these supplements, it seems prudent to avoid such exposure to hexavalent chromium, particularly as
other chromium-containing products are available that passed ConsumerLab.com testing.
So, I just wanted to let you know! If you're taking Mega-T, DexatrimMax, or Natural Factors, you'd be on the safe side to make a change!
