Blue Berry contains a spectrum of intense colored pigments in the form of flavonoids (yellow), anthocyanins (dark purple) and carotenoids (orange) including lutein, which provide complementary support for the eye. These pigments are not only needed to help absorb light for vision but also to protect the light sensing cells in the retina from UV and free radical damage. It helps maintain a healthy macula of the eye in conditions such as cataracts and AMD.
