Nature's Bounty Lutein Blue contains Lutemax 2020, a premium lutein formula containing higher levels of zeaxanthin than free lutein products. It helps filter out damaging blue light and improves eye health when using digital devices. Human bodies cannot make lutein or zeaxanthin, and the natural stores of these carotenoids in the body may decrease as we age. In addition to Lutemax 2020, Nature's Bounty Lutein Blue contains zinc and beta-carotene for added eye health support.
