If you're questioning which vitamin to take every day, Super 1 Daily will take the confusion out of your decision. Just a single tablet of this extra-strength multivitamin and mineral formula per day provides balanced amounts of important nutrients, plus lutein, which promotes healthy vision. Lutein is a carotenoid found in fruits and vegetables that's present in high amounts in and around the macula. Studies suggest high levels of lutein in eye tissue are associated with healthy vision.
