Why Zinc for Vision
Zinc plays a supporting role in vision. Involved in over 300 enzymes and critical for immune function, wound healing, protein synthesis, and DNA repair. Zinc picolinate and zinc bisglycinate are the best-absorbed supplemental forms, while zinc oxide has poor bioavailability.
What dose to look for
Clinical studies typically use 15–30 mg of zinc. Common supplement dose; UL is 40 mg/day. Products below this range may not deliver meaningful results.
What form to look for
Avoid zinc oxide — poorly absorbed. Avoid zinc sulfate — lower absorption, may cause nausea. Look for zinc picolinate or zinc bisglycinate for better absorption.
What the research says
Zinc has strong clinical evidence for vision benefits. Meta-analyses of 30+ trials confirm immune benefits; reduces common cold duration by ~33% Learn more
Clinical research on Zinc
HIGH — Core AREDS/AREDS2 component · 25–80 mg/day (AREDS2 used 25 mg oxide equivalent)
- •Original AREDS trial (2001, 3,640 participants) found zinc 80 mg/day + antioxidants reduced risk of advanced AMD by 25%. Zinc alone reduced risk by 21%. PubMed
- •AREDS2 reduced zinc from 80 mg to 25 mg with no loss of efficacy, while reducing GI side effects and copper depletion risk.
- •Zinc is essential for retinal function — retinal pigment epithelium has one of the highest zinc concentrations in the body. Deficiency impairs visual adaptation and retinal health.
