Research has found that taking around 15 to 40 mg of lutein daily can offer the best possible protection for most people. Since most individuals struggle to eat enough leafy, green vegetables and egg yolks, the average amount of lutein we get in our diet is about 2 mg a day. This is why supplements can be such an important consideration.
When we take lutein in supplemental form or eat foods with lutein, the substance is transported quickly and easily around the body, particularly to the lens and macula of the eye. It should be noted that there are more than 600 different carotenoids in the natural world, but only around 20 can actually have an impact on our eye sight.
