Supplement comparison results

Primary ingredients How we evaluate

We evaluate daily recommended amount (mg) fulfillment and examine whether lutein and zeaxanthin ratio and combination effectively maintain macular pigment density and visual protection. We particularly review AREDS2 formula fulfillment for clinical evidence-based combinations, and examine astaxanthin content and extraction method (supercritical, etc.) for antioxidant effect enhancement.

Price How we evaluate

We calculate unit price based on mg standard to compare cost-effectiveness relative to ingredients. We focus on practical cost-effectiveness considering actual content, absorption rate, and combination efficiency rather than just price.

Brand How we evaluate

We confirm GMP and health functional food certification, non-GMO, Traceability, Kosher, Halal certifications, and other quality certifications. We comprehensively review raw material manufacturer transparency, origin labeling, and supply chain management.

Quality How we evaluate

Since lutein is fat-soluble, we carefully evaluate fat-soluble capsule formulation, solvent use, and individual packaging. We evaluate practical consumption convenience (capsule size, dosing frequency) and oxidation-prevention packaging stability.

Additional ingredients How we evaluate

We verify inclusion of functional components supporting vision and macular health (berry types, astaxanthin, antioxidants, etc.). We review AREDS2 component fulfillment (zinc, vitamin C, E, etc.) and evaluate unnecessary additive absence and allergen potential.
