NEW YORK (Reuters) - Six dietary supplements sold by Herbalife Ltd contain dangerous amounts of lead if taken in the recommended dosages, according to information posted on Monday on a Web site linked to a long-time critic of the firm.
Herbalife disputed the claim, saying its weight-loss and nutritional products met regulatory requirements in all of its markets.
"The FDA hasn't established a general limit on lead in foods, but we are certainly well within their suggested guidelines," Herbalife spokesman George Fischer said in a telephone interview, referring to the U.S. Food and Drug Administration, which sets dietary guidelines.
The Fraud Discovery Institute posted a letter on its Web site on Monday attributed to Christopher Grell, an attorney in Oakland, California, who specializes in product liability cases.
The letter said recommended daily doses of six Herbalife products contained levels of lead that are dangerous and in excess of what California law allows under its Safe Drinking and Toxic Environment Act. It urged the state to order Herbalife to place "clear and reasonable warnings" on those products.
Barry Minkow, founder of the institute, has $50,000 invested in Herbalife "put" options, betting that the company's shares will fall.
Minkow, a San Diego pastor who served more than seven years in jail for stock fraud, now works to uncover fraud through the institute. He has a history of criticizing Los Angeles-based Herbalife.
Minkow said in a telephone interview that his bet that the company's shares will fall was only intended to finance his investigation.
California law requires businesses to warn consumers if their products contain chemicals known to cause cancer or reproductive toxicity.
The six products mentioned in the letter are the ShapeWorks Protein Drink Mix, Healthy Meal Nutritional Shake Mix, Tang Kuei Plus herbal tablets, Thermojetics Nature's Raw Guarana instant tea mix, ShapeWorks Cell Activator and Multivitamin Complex.
The company says products are sold in 65 countries by a network of over 1.8 million distributors.
