A carotenoid concentrated in the macula of the eye, filtering blue light and protecting against oxidative damage. Also accumulates in the brain and is associated with faster cognitive processing speed.
Why this form
Derived from Tagetes erecta (marigold) flowers and standardised to ≥20% lutein by HPLC analysis — the consistent, measurable potency that separates a precision ingredient from a commodity extract. Marigold-derived lutein is the form used across the clinical evidence base for ocular and cognitive health.
Key benefits
Macular support & vision
Lutein is selectively accumulated in the macula — the central high-acuity region of the retina. It forms the macular pigment that absorbs high-energy blue light, contributing to the protection of photoreceptors from photo-oxidative stress.
Blue light filtration
Both lutein and the naturally co-occurring zeaxanthin act as biological filters, absorbing the blue light wavelengths (415–455nm) associated with retinal photo-oxidative stress — relevant for screen-heavy modern lifestyles.
Cognitive performance
Lutein accumulates in the brain as well as the eye, and is associated with normal cognitive processing speed and attention in published nutritional research.
