Lutein: The New Anti-Aging Supplement

0

Lutein supplements got seniors up and moving in a study from the University of South Australia. Forty-four seniors who did not meet the Australian physical activity guidelines were given daily placebos or supplements of lutein (21 milligrams), and were encouraged to exercise more. After one month, those seniors taking lutein showed increased blood levels of the carotenoid and a significant reduction in sedentary time. In fact, the percent change in blood lutein was directly associated with the increase in daily activity. The more, the better.
