Xanthophylls

Xanthophylls are yellow-orange carotenoid pigments that selectively accumulate in the macula of the eye, providing critical protection against blue light damage and oxidative stress. Research shows the two primary dietary xanthophylls—lutein and zeaxanthin—form the macular pigment that shields photoreceptors and improves visual performance. The landmark AREDS2 study demonstrated that supplementing with 10 mg lutein and 2 mg zeaxanthin daily reduced progression to advanced age-related macular degeneration by 26% in high-risk individuals. Beyond eye health, emerging research links higher xanthophyll levels to improved cognitive function, reduced inflammation, and better skin health. While naturally found in dark leafy greens, corn, orange peppers, and egg yolks, most supplements derive these compounds from marigold flowers. For optimal absorption, take with meals containing fat, as these are fat-soluble compounds that require dietary fat for proper absorption.
