— Testing Finds One Brand with 215% of the Labeled Amount —
WHITE PLAINS, NEW YORK — SEPTEMBER 19, 2006 — New tests of supplements containing the hormone DHEA found most to contain their claimed amounts of the controversial ingredient, but one provided 215% of its stated amount, the testing company reported today. Dehydroepiandrosterone (DHEA), a steroid now banned from use by certain athletic organizations, has been touted for its potential to "reverse the aging process" and "increase strength."'s new Product Review of DHEA Supplements scrutinizes these claims as well as the quality of products on the market. Sales of DHEA jumped from just $1 million in 1998 to $48 million in 2004, according to figures from Nutrition Business Journal.

"DHEA levels fall with age, which is why it has been promoted as a 'fountain of youth,' said Tod Cooperman, MD, President of "Several studies have shown that it does not improve strength, nor improve general well-being in seniors. But DHEA may improve skin condition, sexual dysfunction, and osteoporosis in older individuals. It may also help people suffering from lupus reduce their corticosteriod use." He warned, however, that, "DHEA has potential side effects and it should only be used with caution in women with hormone-sensitive breast cancer. The risk of side effects could increase if using a product containing more ingredient than claimed on its label."

This is the second time that has reviewed DHEA supplements. In December 2002, found three products to contain less DHEA than claimed.
