BioStacksLutein and vision
When it comes to vision, Lutein is one of the most key nutrients to consider. Lutein is a xanthophyll carotenoid that accumulates in the macula and lens of the eye, where it filters harmful blue light and acts as an antioxidant. The AREDS2 trial (5,000+ participants) confirmed lutein + zeaxanthin reduced the risk of advanced AMD progression. Unlike beta-carotene, lutein is safe for smokers.
Effective dosing
Most evidence supports 10–20 mg of lutein daily. AREDS2 study used 10 mg/day; common eye health supplement dose. Products below this range may not deliver meaningful results.
What the research says
