HelloPharmacist Scorecard of Krill Oil 500 mg by Absorb Health

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Aug 13, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

Absorb Health Krill Oil 500 mg contains one active ingredient: krill oil, a marine lipid rich in omega-3 fatty acids. The capsule itself is made from gelatin.

Does it work?

Not established
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Krill Oil's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Anti-inflammatory support.
  • We looked for evidence on: Dysmenorrhea, Exercise-induced muscle damage, Osteoarthritis, Rheumatoid arthritis (RA), Joint inflammation, Inflammatory conditions.
  • The closest evidence on file: Krill Oil is rated "Insufficient Reliable Evidence To Rate" for Osteoarthritis (Natural Medicines).
  • Also on file: Krill Oil is rated "Insufficient Reliable Evidence To Rate" for Rheumatoid arthritis (RA), Dysmenorrhea, Exercise-induced muscle damage.

The clearest evidence backs krill oil for dry eye, where it's rated possibly effective. For aging skin, Alzheimer disease, cancer, high cholesterol (hyperlipidemia), and cognitive function, the evidence isn't strong enough to rate — we just don't have reliable data yet on how well it works for those uses.

The evidence, ingredient by ingredient Krill Oil

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Krill oil is generally well tolerated, with most people taking up to 4 grams daily without serious problems. Common side effects are mild and digestive: bloating, diarrhea, fishy burps, flatulence, heartburn, nausea, and stomach discomfort.

These tend to be less frequent or less severe than with fish oil. Headache, tiredness, and dizziness have been reported rarely.

You should avoid krill oil if you have a shellfish allergy, and use caution if you have a bleeding disorder. There isn't enough reliable safety data to know whether krill oil is safe during pregnancy or breastfeeding — talk with your doctor or pharmacist for personalized advice before using it.

Side effects, ingredient by ingredient Krill Oil

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Krill Oil.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 208 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Check with your doctor or pharmacist before taking this if you're on blood thinners (anticoagulants) like warfarin or blood-clotting preventers (antiplatelets) like aspirin — Moderate risk of bleeding. Also confirm your diabetes medications first, since krill oil might lower blood sugar — also Moderate risk.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Krill oil is worth considering if you're looking for help with dry eye. But if you take blood thinners or diabetes medications, you'll need to check your specific drugs with your doctor or pharmacist first — the interactions are real.

Side effects are usually just digestive upset. It's not established for other uses yet, so manage your expectations there.

Krill Oil2 drug types · 208 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, krill oil may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Taking high doses of omega-3 fatty acids from fish oil can modestly decrease platelet aggregation. Since krill oil also contains these fatty acids, taking high doses of krill oil might also inhibit platelet aggregation. Theoretically, taking high doses of krill oil with antiplatelet or anticoagulant drugs might increase the risk of bleeding. However, the omega-3 content of krill oil is much lower than that of fish oil.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, taking krill oil with antidiabetes drugs might increase the risk of hypoglycemia.
Some research in animals and humans shows that krill oil might lower blood glucose levels. However, a small study shows that taking krill oil does not reduce blood glucose levels in patients with type 2 diabetes, most of whom were taking antidiabetes drugs.

Krill Oil 500 mg by Absorb Health: Common Questions

Does Krill Oil 500 mg by Absorb Health interact with any medications?
Yes. Based on its ingredients, Krill Oil 500 mg has a known interaction with 208 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Krill Oil 500 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Will krill oil give me bad side effects?
Most people tolerate it well at doses up to 4 grams daily. You might have some digestive complaints — bloating, diarrhea, fishy burps, heartburn, or nausea — but they're usually mild and happen less often or less severely than with fish oil. Headache, tiredness, or dizziness are rare.
Can I take this if I'm allergic to shellfish?
No — avoid it. Krill oil comes from krill (tiny crustaceans), and if you have a shellfish allergy, you should skip this product.
Is krill oil safe during pregnancy or breastfeeding?
There isn't enough reliable safety data to say either way. Talk with your doctor or pharmacist for personalized advice before using it.
What is krill oil supposed to help with?
The strongest evidence supports its use for dry eye, where it's rated possibly effective. For aging skin, Alzheimer disease, cancer, high cholesterol, and cognitive function, we don't yet have reliable data showing how well it works.
Can I take this with fish oil?
The product facts don't cover combining krill oil with fish oil. Since both contain similar omega-3 fatty acids, talk with your doctor or pharmacist about whether taking both makes sense for you.
