Lutein and Zeaxanthin are powerful anti-oxidant carotenoids found in fruits and green leafy vegetables. These nutrients are naturally found in the macula of the eye. The macula is located in the centre of the retina and is responsible for good central vision.

Many studies have shown that Lutein and Zeaxanthin may help to shield the macula from damaging light and to protect it from harmful oxidization. With advancing age, these essential nutrients decline in the macula, which may lead to a deterioration or even loss of eyesight. Age-related Macular Degeneration (AMD) is the leading cause of visual impairment in Western society today.

The recently published Lutein Anti-oxidant Supplement Trial (L.A.S.T.) examined lutein’s role in AMD. The study suggests that AMD is, at least in part, nutrition responsive and that supplementation, particularly with lutein, may improve eye function and slow the progression of AMD. The L.A.S.T. Study clearly supports what scientific research has been unveiling for several years – the role of lutein in eye health.

The most recent scientific research on lutein supplementation supports a minimum daily intake of 6mg to help protect the macula from damaging light and oxidization. Leading multivitamin brands now contain added lutein but the daily dosage amounts typically provide only 1mg or even less. Since the average diet provides only 2mg lutein, supplementation with multivitamins is insufficient to provide this minimum daily intake of 6mg.
