Best Supplements for Vision & Eye Health

Healthy vision depends on protective macular pigments, adequate structural lipids in the retina, and antioxidant defense against light-induced oxidative stress. Research suggests that the carotenoids zeaxanthin and lutein, alongside astaxanthin and Omega-3 fatty acids, each support distinct aspects of healthy eye function and macular pigment density. FormulaForge ranks every ingredient by the bioavailability of its available forms so you can select the most effective options.

Frequently Asked Questions

What supplements may support healthy vision and eye health?

Lutein and zeaxanthin (macular carotenoids), astaxanthin, and Omega-3 fatty acids (DHA in particular) are among the most studied ingredients for supporting healthy macular pigment density and visual function. These supplements are not intended to diagnose, treat, cure, or prevent any eye disease. Consult a qualified healthcare provider for persistent vision concerns.

How do lutein and zeaxanthin support eye health?

Lutein and zeaxanthin are carotenoids that concentrate in the macula, where they form the macular pigment and help filter high-energy visible light. A review of their role across the lifespan (Erdman et al. 2014; PMID 25109868) summarizes evidence that these carotenoids support healthy visual and cognitive function, and a randomized, placebo-controlled trial in older adults (Olmedilla-Alonso et al. 2021; PMID 34579067) reported associations between carotenoid supplementation and night-vision measures. These are structure/function observations — they are not a treatment for any eye disease.

What does astaxanthin do for the eyes?

Astaxanthin is a carotenoid antioxidant studied for supporting the body's defense against oxidative stress, including in tissues exposed to light. Research suggests it may support healthy eye comfort and resilience. The strongest evidence base for macular-pigment support remains with lutein and zeaxanthin; astaxanthin is offered as a complementary antioxidant. These are structure/function claims only.

What role do omega-3 fatty acids play in eye health?

DHA is a major structural fatty acid in the retina and is involved in healthy photoreceptor membrane function. Research suggests that maintaining adequate DHA intake supports healthy visual function. Triglyceride-form and phospholipid-form Omega-3 sources offer the highest bioavailability in our /100 form-score rankings. These are structure/function claims.
