"Age-related Macular Degeneration is the leading cause of untreated vision loss in aging Western societies, accounting for 45% of all visual disability. Low intake of Lutein is a major risk factor for advanced ARMD"

Epidemiologic studies such as this one conducted by Harvard University (Dr. Johanna Seddon) show a correlation between the intake of lutein and the risk of developing AMD. These researchers found that people that consumed 6 mg of lutein per day had 57% lower risk of developing AMD relative to those consuming only 0.5 mg/day. These findings are supported by the fact that a similar relationship exists between intake of spinach (food high in lutein) and AMD. It is also supported by data showing an inverse relation between serum lutein levels and AMD risk.

Average Lutein consumption in Europe is 2.2 mg/day.
O’Neill M.E. et al, 2001

The suggested daily Lutein intake for prevention of AMD is 6mg from foods and/or supplements.

Now with LAST, recommended dose may rise to 10 mg/day!
