Lutein
别名: lutein and zeaxanthin, meso-zeaxanthin, eye carotenoids
Lutein and zeaxanthin are yellow carotenoids from leafy greens and egg yolk that accumulate in the macula of the retina. They filter blue light and protect the eye from oxidative damage.
用途
- Slower progression of advanced age-related macular degeneration – moderate evidence (as part of the combination from the large AREDS2 trial)
- Higher macular pigment density – moderate evidence
- Contrast sensitivity and eye fatigue – weak evidence

不宜同服 / 需错开
