What the evidence supports: raising omega-3 blood levels; outcome evidence largely comes from fish oil trials.

This scores how well-supported the claim above is — not how much benefit you personally would get. A high score on a narrow claim does not extend to everything the product is marketed for.

How long to take it

Ongoing, like fish oil, unless you eat oily fish regularly.

Who it's actually for

People who prefer small capsules and don't mind paying more per gram of EPA+DHA.

Safe upper limit

Unverified
Treat as equivalent to fish oil — about 3 g combined EPA+DHA per day from supplements
Same blood-thinning consideration as fish oil at high doses. Crustacean-derived, so avoid with shellfish allergy.

Practical notes

  • Compare EPA+DHA per serving — krill capsules often contain much less than fish oil.
  • The absorption advantage doesn't make up for low doses in many products.
  • Avoid with shellfish allergy.
