12mg Lutein and 4mg of zeaxanthin daily are proven to be beneficial for eye health. Unfortunately, our bodies cannot produce these essential nutrients. We need to get them from foods and supplements. However, most people do not consume enough of the fruits and vegetables to provide the daily requirement for lutein and zeaxanthin.
It is recommended to consume at least half a cup of cooked spinach or Swiss chard, one cup of collard greens or turnip greens, or four cups of romaine lettuce to provide the lutein and zeaxanthin your body needs.
