WEDNESDAY, Dec. 15 (HealthDay News) -- U.S. health authorities
Wednesday intensified pressure on makers of dietary supplements,
warning individuals or companies marketing "tainted" products that
they could face criminal prosecution, among other consequences.
The move comes after several reports of injury and even death
from the use of illegal supplements that are deceptively labeled or
contain undeclared ingredients. These include those laced with the
same active ingredients as drugs already approved by the U.S. Food
and Drug Administration, analogs (close copies) of those drugs or
novel synthetic steroids that don't qualify as dietary
"Some contain prescription drugs or analogs never tested in humans and the results can be tragic," said Dr. Joshua Sharfstein, principal deputy commissioner at the FDA, at a Wednesday news conference. "We have received reports of serious adverse events and injuries associated with consumer use of these tainted products, including stroke, liver and kidney damage, pulmonary failure and death."
Since 2007, he added, FDA has issued alerts on 300 tainted
"FDA is calling attention to an important public health problem," Sharfstein said. "Serious injuries have resulted from products masquerading as dietary supplements. . . They're usually poorly labeled so consumers don't know what they're buying."
Most of the illegal products are marketed in three categories:
to promote weight loss, to enhance sexual prowess and as
body-building products, the agency noted.
The weight-loss products identified with problems include
Slimming Beauty, Solo Slim and Slim-30, which contain sibutramine
(or analogs), the active ingredient in the FDA-approved drug
Merida, recently withdrawn from pharmacy shelves due to a
heightened risk of heart attack and stroke.
The body-building products include Tren Xtreme, ArimaDex and
Clomed, which contain anabolic steroids or aromatase inhibitors, a
class of cancer-fighting drugs that interfere with estrogen
production. Consumers should also be aware of "products that
provide warnings about testing positive in performance drug tests,"
The sexual-enhancement products tend to include the active
ingredient or an analog of the popular approved
erectile-dysfunction drugs Viagra, Cialis and Levitra. Illegal
products include Vigor-25, Duro Extend Capsules for Men and Magic
Power Coffee. In particular, sexual enhancement products promising
rapid effects in minutes to hours or long-lasting effects of 24 to
72 hours, should be viewed with caution, the agency warned.
Consumers should also be skeptical of products that claim to be
alternatives to or similar to FDA-approved drugs; those that say
they are a legal alternative to anabolic steroids; and those
marketed primarily in foreign languages and through mass e-mails,
FDA is launching a new RSS feed, which is a Web-based service,
so consumers can keep abreast of rapidly changing developments
regarding tainted supplements and other products.
The agency is also introducing a new way for industry to refer
suspects, including referring them anonymously, Sharfstein
Representatives from five trade associations representing the
dietary supplement industry -- the Council for Responsible
Nutrition, Natural Products Association, United Natural Products
Alliance, Consumer Healthcare Products Association and American
Herbal Products Association -- also spoke at the news conference
pledging their support, including help putting out the word within
"We want to drive these pirates out of our industry to protect the public health and safety of millions of consumers who do rely on these products for daily health needs," said Loren Israelsen, executive director of the United Natural Products Alliance.
"We have been astonished at the unfortunate growth of this particular class of products, which are intentionally spiked," Israelsen added. "These are illegal products marketed by people who work in the shadows. They are difficult to find but we are committed to working with FDA to find them and drive them out of our industry and out of the U.S."
Legitimate dietary supplements are regulated under the Dietary
Supplement Health and Education Act of 1994. They do not have to be
approved by the FDA before reaching consumers, but manufacturers
are expected to ensure standards.
