DHA wins on 2 of the measurable metrics.
It absorbs at 85% against 95%, which is the number that decides how much of the dose actually reaches you.
What actually differs
DHA
Essential omega-3 fatty acid crucial for brain development, cognitive function, eye health, and neurological wellness throughout life
- Superior absorption
- Natural form
- Better stability
- Proven effectiveness
- Higher cost
- Larger capsules
- Fishy taste potential
- Storage requirements
Krill Oil
Premium marine oil from Antarctic krill containing phospholipid-bound omega-3 fatty acids and astaxanthin for superior absorption and antioxidant protection
- Superior absorption
- No fishy burps
- Antioxidant protection
- Sustainable source
- Higher cost
- Shellfish allergy risk
- Limited research vs fish oil
- Smaller omega-3 content per capsule
How these numbers are read
- Bioavailability is the share of the dose that reaches your bloodstream — the single most useful number when choosing a form.
- Safety rating reflects tolerance at normal doses, not toxicity risk.
- Cost is per month at the typical daily dose, so a cheaper form taken at double the dose is not cheaper.
- Evidence level A means the form itself was studied, not just the parent compound.

Common questions
Which is better, DHA or Krill Oil?
Krill Oil absorbs better — 95% against 85%. Absorption decides how much of the dose actually reaches you, so it usually matters more than the milligrams printed on the label.
What is the difference between DHA and Krill Oil?
Both deliver the same active compound. They differ in how well the body takes them up, how they are tolerated and what a month costs: $50 against $60.
Can you take DHA and Krill Oil together?
You can, but there is rarely a reason to. Two forms of the same compound stack the same active dose, so the usual approach is to pick the better absorbed one and dose it properly.
