How long do Lutein and Zeaxanthin take to build up in the macula?
3–6 months of consistent daily supplementation. Both iGenics (365-day guarantee) and Vision 20 (180-day guarantee) allow adequate evaluation time. Both provide Lutein at the AREDS2-research-aligned 20mg dose.
What does Taurine do for vision?
Taurine is an amino acid highly concentrated in the retina, it is essential for photoreceptor function and protecting the retina from oxidative damage. It is not included in the core AREDS2 formula but has significant independent research support.
Is Saffron in iGenics evidence-based?
Saffron has produced promising results in several human studies on macular function, including improvements in photoreceptor function and visual acuity. The evidence is emerging rather than definitive.
