Why Xanthogreen

Free lutein takes months
to deposit on the macula.

Lutein is a naturally occurring carotenoid concentrated in the macula, where it plays an important role in supporting visual health. Xanthogreen® takes a more advanced approach, delivering lutein in esterified form, in a shorter time.

01
Solvent free
Extracted with a patented supercritical fluid extraction (SCF-CO₂) process.
02
Stability
Lutein esters, naturally present in marigold flowers, are the most stable form.
03
Grades
Xanthogreen® is available in three grades, each clinically studied.
04
Fast onset
Macular pigment rose significantly against placebo from day 30.

The approach

Three grades for
different formats.

It disperses the lutein esters in a homogenous oil: stable, solvent-free, and broken into a nanoemulsion in the gut for better absorption.

Macular pigment optical density, change from baseline. Significant from day 30 on all three grades; ULTRA at half the lutein dose.

01
A true oil solution
Breaks into a nanoemulsion in the gut, for better absorption.
02
The lymphatic route
Lutein esters are absorbed mainly through the lymphatic system, avoiding first-pass metabolism (degradation in the liver).
03
4 weeks
Measurable lutein reaches the retina.
