Research Area: Eye Health
8 ingredients studied for effects on Eye Health — sorted by research relevance.
Ergothionein
Ergothioneine is a sulfur-containing amino acid found primarily in mushrooms, studied for potential antioxidant and age-related benefits despite limited human evidence.
Astaxanthin
Astaxanthin is a membrane-spanning carotenoid antioxidant. Small RCTs show consistent benefits for skin protection and visual fatigue; cardiovascular and longevity data remain limited.
Omega-3 (EPA + DHA)
Omega-3 fatty acids (EPA + DHA) are among the most thoroughly studied supplements. Evidence is strong for triglycerides and high-risk cardiovascular patients; smaller for healthy individuals.
Taurin
Taurine is an amino acid with a central role in energy metabolism. Animal and observational data have sparked aging research interest; robust human evidence is far more limited.
Zinc
Zinc is involved in hundreds of enzymes and is essential for immune function, DNA repair, and hormone synthesis. Low intake is not uncommon in older adults and vegans.
Lutein & Zeaxanthin
Xanthophyll carotenoids that concentrate in the macula. Strong evidence for slowing AMD progression (25% reduction in AREDS2). Also studied for contrast sensitivity, glare, and cognitive function.
Vitamin A
Essential for vision, skin, and immune function. Clearly useful for deficiency, but high doses are toxic—especially in pregnancy.
Hyaluronsäure
Endogenous glycosaminoglycan with high water-binding capacity. Multiple RCTs demonstrate moderate effects on skin hydration and wrinkle reduction; oral joint data weaker.
