WHITE PLAINS, NY — January 29, 2004 — ConsumerLab.com announced today that only one of the 19 lutein/zeaxanthin supplements it recently tested failed to contain the claimed ingredients. Although product quality was generally high, ConsumerLab.com found the suggested dosage of products to vary widely — from 0.25 to 22.5 mg (milligrams) per day, a 90-fold difference. Intake of appropriate amounts lutein and/or zeaxanthin may reduce the risk of macular degeneration and cataracts.
Lutein and zeaxanthin are antioxidant pigments found in highest concentration in the macula of the eye where they may help protect it from damage. Dietary intake of about 6 mg per day of these antioxidants is associated with a reduced risk of macular degeneration — the leading cause of blindness in developed countries — and cataracts. Most adults, however, get only 2 to 4 mg per day of lutein and zeaxanthin from their diet. This has lead to the popularity of lutein and zeaxanthin supplements, from which these compounds are absorbed equally as well as from foods. U.S. sales of lutein supplements increased to $100 million in 2002 from only $30 million in 1999 according to Nutrition Business Journal.
"People trying to reduce the risk of eye disease should to get at least 6 mg per day of these eye-specific anti-oxidants. A half cup of spinach, for example, provides this amount," said Tod Cooperman, M.D., President of ConsumerLab.com. "There are many good supplements out there, but people should carefully check the dosage. Products with less than 1 mg won't contribute much and it is not known whether high doses, such as 20 mg, carry added benefit."
