Supplement Comparison
Fish oil is the default for most people: high EPA, affordable, well studied. Krill oil or salmon roe is argued to be better for getting DHA into the brain, but fish oil is still the usual pick.

DHA Brain Delivery
Fish Oil
DHA in triglyceride form — less efficient at crossing blood-brain barrier
Krill Oil
DHA in phospholipid form, which uses the MFSD2A transporter for better brain uptake
EPA Content
Fish Oil
High — can get concentrated EPA formulations (1-4g per serving)
Krill Oil
Lower EPA per serving — typically 50-100mg EPA
Bioavailability
Fish Oil
Good in triglyceride form (avoid ethyl ester)
Krill Oil
Higher overall bioavailability; phospholipid binding aids absorption
Best For
Fish Oil
Cardiovascular health, inflammation, mood (EPA-focused)
Krill Oil
Brain health, cognitive function, DHA delivery
Cost
Fish Oil
$15-30/month for quality product
Krill Oil
$30-60/month — significantly more expensive
Research Base
Fish Oil
Extensive — REDUCE-IT trial (4g EPA), hundreds of studies
Krill Oil
Growing — strong mechanistic data on MFSD2A transporter
High-EPA fish oil is the usual pick: it's well studied, affordable, and delivers the EPA behind the heart and mood benefits. The case for krill oil (or salmon roe) is that the brain needs DHA in phospholipid form, which standard fish oil does not provide. If your main goal is heart health and inflammation, fish oil is the clear choice. If brain health is your priority, the MFSD2A transporter data make a case for krill. Some people take both: fish oil for EPA and krill or salmon roe for brain DHA. Either way, test your omega-3 index and aim for 8-12%.
