You're getting 20mg of **Lutein** per softgel — right at the top of the clinically studied range from the landmark AREDS2 trial, which used 10mg/day and showed reduced risk of advanced macular degeneration. At this dose, you're well above the minimum and fully covered for long-term eye health support, including filtering blue light and protecting the macula from oxidative damage.

**Zeaxanthin** complements lutein by concentrating at the very center of your sharpest vision (the fovea), where lutein doesn't reach as well. The softgel format helps absorption since both are fat-soluble carotenoids — taking this with a meal that contains some fat will maximize what your body uses.

The gap worth noting: **Zeaxanthin** is dosed at just 1mg, while the AREDS2 trial used 2mg. You're getting half the studied dose of this ingredient, so if complete macular pigment coverage is your goal, the zeaxanthin side of the formula falls short.
