About Omega-3

Fallback nutrient for products that only list total omega-3 without EPA/DHA breakdown. When EPA and DHA are listed separately on the label, they are scored as individual nutrients with their own clinical dose ranges. Absorption depends heavily on molecular form: re-esterified triglyceride (rTG) is ~70% better absorbed than the cheaper ethyl ester (EE) form.

What Omega-3 supports

  • Supports heart health
  • Supports brain function

How much Omega-3 to take

Clinical studies typically use 1000–3000 mg of Omega-3. Total omega-3 from fish oil or algae. Fallback when EPA/DHA not listed separately.

Effective range
1000–3000 mg

Forms of Omega-3 compared

  • Triglyceride form (rTG)Premium
    Natural fish-oil structure; ~70% better absorbed than ethyl ester.
  • Ethyl ester (EE)Standard
    Lower absorption than triglyceride
  • Flaxseed (ALA)Budget
    ALA omega-3 — only ~5-10% converts to EPA/DHA

Clinical evidence

Strong clinical evidence. Thousands of trials; meta-analyses confirm triglyceride reduction of 15-30% and modest cardiovascular benefits. See EPA and DHA for specific clinical profiles.
