Lutein + Zeaxanthin
Carotenoids protecting retinal health and filtering blue light.
By Suplagen Team · Updated
What it is
Lutein and zeaxanthin are macular carotenoids that accumulate in the retina, protecting photoreceptors from blue light and oxidative damage.
How it works
Filter high-energy blue light in the macula; quench reactive oxygen species; protect photoreceptor cells from phototoxicity.
What the evidence says
Strong evidence for macular health (AREDS2 trial); moderate evidence for blue light filtering and skin photoprotection.
How much to take
The catalog range is 10 to 20 mg daily, with 20 mg as the ceiling. The benchmark is the AREDS2 formula: 10 mg lutein with 2 mg zeaxanthin, the dose behind the strong evidence for macular health.
There's no reason to exceed it. The trials that matter used that exact combination, and it's safe for long-term use.
When and how to take it
With a fat-containing meal; both carotenoids are fat-soluble. Once daily, any time.
It's an eye supplement first, with moderate evidence for blue light filtering and a place in our skin guide for photoprotection. Marigold-derived is the common source.
Who should skip it
No contraindications and no drug interactions are listed, and it's safe in pregnancy. One of the cleanest entries in the catalog; the only mistake is taking it without fat.
Safety Notes
- AREDS2 formula dose: 10 mg lutein + 2 mg zeaxanthin. Safe for long-term use. Marigold-derived is most common source.
Common questions
What is the recommended dosage of lutein and zeaxanthin?
10 mg lutein with 2 mg zeaxanthin, the AREDS2 dose. The catalog range runs 10 to 20 mg total, with 20 mg as the ceiling.
When should I take lutein?
With a meal that contains fat, at any time of day. Absorption depends on the fat, not the clock.
Is lutein safe long term?
Yes. The catalog notes it's safe for long-term use, with no listed interactions or contraindications.
