U.S. warning consumers about 'fountain of youth' hormones
April 10, 1997
Web posted at: 5:20 p.m. ESTWASHINGTON (CNN) -- The U.S. government is launching a public education campaign in an effort to warn consumers of possible dangers associated with taking hormones that promise to slow the aging process.
Hormones like DHEA and melatonin have become immensely popular among baby-boomers, as nutritional supplement manufacturers market them as "fountains of youth." Books like "The Melatonin Miracle" and "The Superhormone Promise" have fueled interest in the supplements.
Now the National Institute on Aging, a division of the National Institutes of Health, says consumers should use caution. According to the NIA, despite popular claims, none of the hormones -- including DHEA, melatonin, human growth hormone, testosterone, and estrogen -- has been shown to prevent or reverse aging.
The agency says research ultimately may reveal important health benefits from some of the supplements. But in the meantime, scientists are concerned about the possibility of dangerous side effects.
For example, the agency says there are indications high doses of DHEA can cause liver damage, and may be linked to increased risk for breast and prostate cancers.
It also says high testosterone levels in women can lead to facial hair growth and changes in blood fats, which increase the risk for heart disease.
DHEA and melatonin became available over the counter in the United States in 1994 when Congress passed a law deregulating nutritional supplements. But the NIA says people shouldn't take DHEA until further research proves its benefits and determines a safe dosage.
The NIA is encouraging TV stations to start airing its new public service announcements this month. The PSAs advise consumers to call a toll-free number -- 1-800-222-2225 -- for a free fact sheet about hormone supplements.
