Lutein

Lutein is a yellow carotenoid with antioxidant properties, often associated with eye health. In this context, it may help protect against disruption from nighttime blue light exposure, supporting natural circadian rhythms and restful sleep—important for metabolic balance. For product comparison, Lutein should be checked by exact form, plant part or compound type, standardization, amount per serving, and whether it is listed as an active ingredient, other ingredient, or part of a blend.
