BioStacksOmega-3 and vision
Omega-3 is a supporting nutrient for vision support. Doses vary by EPA/DHA content — always check combined EPA+DHA per serving, not total fish oil volume. EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are the two primary active omega-3 fatty acids. Absorption depends heavily on molecular form: re-esterified triglyceride (rTG) is ~70% better absorbed than the cheaper ethyl ester (EE) form common in budget supplements.
How much omega-3 do you need
Research points to 1000–3000 mg as the effective range for omega-3. Total omega-3 from fish oil or algae supplements. Lower doses may provide some benefit, but most studies showing clear results used this range.
Which form absorbs best
Avoid ethyl ester — lower absorption than triglyceride. Avoid flaxseed — ala omega-3 — only ~5-10% converts to epa/dha. The most bioavailable options are triglyceride form (rtg).
What the research says
The clinical evidence for omega-3 in vision is strong. Thousands of trials; meta-analyses confirm triglyceride reduction of 15-30% and modest cardiovascular benefits Learn more
