New findings from the Lutein Antioxidant Supplementation Trial (LAST)

Lutein is an important carotenoid credited with reducing the risk of developing age-related macular degeneration (AMD). A new study published in the April 2004 edition of Optometry, Journal of the American Optometric Association, further confirms that lutein (10-mg/day) alone, or combined with additional carotenoids, antioxidants, and minerals (including zinc), significantly improves macular pigment optical density and glare recovery, near visual acuity, and significantly improves most measures of quality of vision.

These results are important because lutein is an essential carotenoid obtained only from dietary sources. The researchers suggest that AMD is, at least in part, a nutrition-responsive disorder, and supplementation (particularly with lutein) may improve eye function and slow the progression of AMD.
