New Nordic Blue Berry Strong - Scandinavia's most popular eye health supplement, formulated with highly concentrated bilberry extract and lutein for the preservation of optimal eyesight during the aging process. Bilberry is a special blueberry species which contains high levels of anthocyanins, or the deep purple pigment, which has excellent antioxidant properties and helps protect the eyes and maintain eye health. Lutein is a pigment that is naturally found in dark green leafy vegetables and the marigold flower. Light sensing cells in the eye require this pigment to absorb light and protect from damaging free radicals.
