Builds macular pigment
You want this dense. It is the one retinal measure that dietary intake reliably moves.
In depth
Macular pigment optical density — the lutein and zeaxanthin your retina concentrates into the macula.
What drives it
Micronutrient status increases it.
The median serum concentrations of lutein in participants randomly assigned to receive lutein supplements increased 2 times during the follow-up in comparison with baseline, whereas participants randomly…. PMID 35653117
What it drives
It reduces Supports the aging macula.
The hazard ratio (HR) for progression to late AMD comparing lutein/zeaxanthin with no lutein/zeaxanthin was 0.91 (95% CI, 0.84-0.99; P = .02) ... When the lutein/zeaxanthin main effects analysis was…. PMID 35653117
