HelloPharmacist Scorecard of Krill Oil 500 mg by SimplyBest
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.
What’s inside
Full disclosure
This product contains 4 ingredients total. The active ones are omega-3 fatty acids — specifically DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid) — delivered via krill oil and omega-3 phospholipids.
These are the fish-derived omega-3s your body uses for heart, brain, and cell health. The rest are inactive ingredients: gelatin (capsule shell), glycerin, and purified water.
Does it work?
Not established
The evidence we have covers DHA's use in a few areas. For high cholesterol (hyperlipidemia), DHA is possibly effective — meaning there's some promising research, but it's not definitive.
For premature labor, it's also possibly effective by the same standard. On the flip side, evidence doesn't support DHA for cognitive function or ADHD — it's rated possibly ineffective for both.
EPA's effectiveness isn't established in the data we hold.
How safe is it?
Well-documented data
DHA is generally well tolerated at typical supplement doses. The most common side effects are belching, fishy aftertaste, loose stools, and nausea — usually mild.
Rare reports mention rash, acne, or hair loss, though it's unclear if DHA was the cause. There's also a theoretical concern about increased bleeding risk at high doses, though it's uncommon.
If you're pregnant, DHA is rated likely safe and is often recommended in prenatal care — just use it under your doctor's guidance and pick a purified, low-mercury source. DHA passes into breast milk and is generally considered acceptable, but check with your doctor on the right dose and source for you.
Meds to double-check
Moderate interaction found
Check before taking this if you're on blood thinners or antiplatelet drugs (warfarin, aspirin, clopidogrel) — there's a moderate risk of increased bleeding. Also double-check if you take blood pressure medications or diabetes drugs, since DHA may lower blood pressure further or raise blood sugar.
Use the tool below to verify your exact medications.
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 to support heart or cholesterol health and don't take blood thinners, blood pressure meds, or diabetes drugs — or if you do, you'll need to check with your pharmacist first. Pregnant or breastfeeding?
Talk to your doctor before starting. If you have questions about your specific medications, use the checker on this page.

Krill Oil 500 mg by SimplyBest Drug Interactions
HelloPharmacist Interaction Report
Krill Oil 500 mg by SimplyBest contains omega-3 fatty acids (DHA and EPA) that interact with three major medication types.
The most serious concern is with blood thinners and antiplatelet drugs (medications that prevent blood clots) — DHA may theoretically increase your bleeding risk if you're on warfarin, aspirin, or similar drugs, though most evidence suggests DHA alone doesn't affect clotting on its own.
Read the full breakdown — every affected drug type, severity by severity
You'll also want to check if you take blood pressure medications (antihypertensives) or diabetes drugs. DHA can lower blood pressure, so combining it with blood pressure medicine might push it too low.
For diabetes medications, DHA may raise fasting blood sugar and could reduce how well your oral diabetes drugs work.
We could not check two other ingredients in this product — eicosapentaenoic acid (EPA) and docosahexaenoic acid — because we hold no interaction data for them. Altogether, these interactions span 372 individual medications.

For each ingredient in Krill Oil 500 mg with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Krill Oil
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.
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.
