Forms & variants of Omega-3 (Ethyl Ester)
Different chemical forms of Omega-3 (Ethyl Ester) behave differently. Browse each form's mechanism, bioavailability, and best-use context.
Re-esterified triglyceride EPA/DHA — ~70% better absorption than ethyl ester form.
Phospholipid-bound EPA/DHA from Antarctic krill — includes astaxanthin antioxidant.
Plant-source DHA (and some EPA) from cultivated marine algae — vegan alternative to fish oil.
Mechanism of action
Requires more pancreatic lipase activity for hydrolysis; absorption sensitive to fat intake.

Triglyceride vs ethyl-ester omega-3 absorption
Dyerberg J, et al.
2-week crossover comparing rTG and EE forms.
EE absorbed less than rTG but still raises EPA/DHA at higher doses.
