Finds Most Lutein Supplements Meet Ingredient Claims; Products Vary in Strength

WHITE PLAINS, NY – JANUARY 29, 2004 – 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, 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 led 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.
