éster de luteína de arándano

What is this ingredient? Lutein in this product comes from lutein esters naturally extracted from marigold flowers. Lutein is a yellow xanthophyll carotenoid that the body concentrates in the macula and retina of the eye. There it acts as an internal blue‑light filter and as a potent antioxidant within photoreceptor membranes. Along with its close partner zeaxanthin, lutein helps protect delicate retinal tissue from oxidative stress generated by sunlight, digital screens, and normal visual metabolism.

Dietary lutein from leafy greens and egg yolks is often below the levels associated with optimal macular pigment density. Supplementation with marigold‑derived lutein esters has been shown to raise blood lutein and macular pigment optical density, and is associated with improvements in visual performance such as contrast sensitivity, glare recovery, and support for visual function in bright or high‑screen‑time environments.

Why include it in this formula? From the name “BLUEBERRY LUTEIN ESTER - 60” and the excipient list (syrups, sugars, hydrocolloids, acids, starches, flavors, and a high fruit‑juice content), this product is clearly designed as a chewable or gummy‑style eye‑support supplement. Within that architecture, lutein ester from marigold is the central "macular and blue‑light" pillar. It supplies the specific carotenoid the eye selectively pulls into the macula, helping:

• Filter high‑energy blue light before it reaches photoreceptors
• Neutralize reactive oxygen species in retinal cell membranes
• Support long‑term macular health and visual comfort

The rest of the ingredients—malt syrup, sugars, pectin, carrageenan, gellan gum, starches, juices, and flavorings—create a stable, pleasant‑tasting delivery matrix that makes daily use easy. But it is the marigold‑derived lutein ester that drives the core function: building and maintaining macular pigment to protect the eyes from modern light exposure and to support clear, comfortable vision over time.
