Why DHA for Vision

DHA plays a supporting role in vision. DHA is the primary structural omega-3 in the brain (~97% of brain omega-3s) and retina (~93% of retinal omega-3s). Critical during pregnancy for fetal brain development — minimum 200-300mg DHA recommended. In clinical studies, dha essential for retinal health and vision.

What dose to look for

Clinical studies typically use 250–1000 mg of dha. 250mg minimum for vision/brain maintenance; 500-1000mg for cognitive outcomes. Products below this range may not deliver meaningful results.

What the research says

DHA has strong clinical evidence for vision benefits. DHA constitutes ~97% of brain omega-3s. RCTs confirm benefits for cognitive function, visual acuity, and fetal neurodevelopment. Learn more

Clinical research on Omega-3 (DHA)

MODERATE — DHA is a structural component of retina, but AREDS2 showed no added benefit · 250–500 mg DHA/day

•DHA comprises ~60% of the fatty acids in retinal photoreceptor outer segments. Observational studies consistently link higher omega-3 intake with lower AMD risk.
•However, AREDS2 found no statistically significant benefit from adding DHA/EPA (1,000 mg/350 mg) to the lutein/zeaxanthin + zinc formulation. PubMed
•The disconnect between observational and trial data suggests omega-3 may be important for retinal development and maintenance, but supplementation on top of an adequate diet may not add measurable benefit.
