HelloPharmacist Scorecard of Antarctic Krill Oil by NativePath
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
NativePath Antarctic Krill Oil is a six-ingredient softgel containing krill oil and its active components. The main actives you're getting are eicosapentaenoic acid and docosahexaenoic acid (both omega-3 fatty acids from krill), phospholipids, vitamin A, and astaxanthin — a natural carotenoid antioxidant also found in krill.
The softgels are made with gelatin, glycerol, and water as inactive ingredients.
Does it work?
Strong evidence
Vitamin A is effective for treating vitamin A deficiency and possibly effective for oral leukoplakia, aging skin, measles, ulcerative colitis, and bronchopulmonary dysplasia. Astaxanthin's effectiveness for its proposed uses — age-related cognitive decline, macular degeneration, aging skin, Alzheimer's disease, athletic performance, and carpal tunnel syndrome — has insufficient reliable evidence in the data we hold.
The effectiveness of the krill oil's omega-3 fatty acids and phospholipids isn't established in our database.
How safe is it?
Well-documented data
Vitamin A is generally well tolerated at recommended doses, but high doses can build up in your body and become toxic, causing headaches, dizziness, blurred vision, liver damage, and in rare cases serious effects like pseudotumor cerebri. Pregnant or nursing people should be particularly cautious — high-dose vitamin A (especially retinol forms) can cause birth defects, so stick to recommended amounts.
Astaxanthin is generally well tolerated in studies, but long-term safety data are limited, and there isn't enough information to recommend it during pregnancy or breastfeeding. Some people taking astaxanthin have reported abdominal pain, diarrhea, and red-colored stools; at higher doses, severe stomach pain has been reported in a small number of users.
Meds to double-check
Major interaction found
Check before starting if you take retinoid medications (Major interaction), blood thinners like warfarin, other drugs that can damage the liver, or tetracycline antibiotics (all Moderate). Additionally, if you take drugs metabolized by your liver — a very large category — discuss this product with your pharmacist or doctor, since astaxanthin may theoretically slow how your body breaks them down.
The bottom line
Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. Major medication interactions have been identified, and safety information is well characterized.
This product is worth considering if you're looking for krill oil omega-3s and antioxidant support, but vitamin A interactions with retinoid medications, blood thinners, and certain antibiotics mean you'll want to check your medications first. Pregnant or nursing people should talk with their doctor or pharmacist before starting, since safety data for astaxanthin and the vitamin A dosage matter for these situations.
If you take any prescription drugs, especially acne treatments, warfarin, or tetracycline antibiotics, confirm with your own pharmacist or doctor that this product is right for you.

Antarctic Krill Oil by NativePath Drug Interactions
HelloPharmacist Interaction Report
NativePath Antarctic Krill Oil contains vitamin A and astaxanthin, both of which have documented interactions with medications.
The most serious concern is vitamin A with retinoids (like tretinoin, isotretinoin, and acitretin) — taking them together can cause dangerously high vitamin A levels and additive toxic effects, which is a Major severity interaction.
Read the full breakdown — every affected drug type, severity by severity
Vitamin A also interacts moderately with blood thinners like warfarin, where high doses may increase bleeding risk; hepatotoxic drugs, where high doses could worsen liver damage; and tetracycline antibiotics, where the combination can raise the risk of raised pressure inside the skull (pseudotumor cerebri). Astaxanthin may theoretically decrease the effectiveness of certain medications broken down by your liver, including many common drugs metabolized by CYP3A4 and CYP2B6 enzymes — though this hasn't been confirmed in humans yet, it's worth checking.
We could not check three other ingredients in this product: eicosapentaenoic acid, docosahexaenoic acid, phospholipids, and total omega-6 content. Altogether, these interactions span 903 individual medications.

For each ingredient in Antarctic Krill Oil with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Astaxanthin
Cytochrome P450 2B6 (Cyp2B6) Substrates
Theoretically, astaxanthin may decrease levels of drugs metabolized by CYP2B6.
In vitro research shows that astaxanthin induces cytochrome CYP2B6 enzyme activity in human hepatocytes. This effect has not been reported in humans.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, astaxanthin may decrease levels of drugs metabolized by CYP3A4.
In vitro research shows that astaxanthin induces CYP3A4 enzyme activity in human hepatocytes. This effect has not been reported in humans.
Vitamin A
Retinoids
Concomitant use of retinoids with vitamin A supplements might produce supratherapeutic vitamin A levels.
Retinoids, which are vitamin A derivatives, could have additive toxic effects when taken with vitamin A supplements.
Hepatotoxic Drugs
Theoretically, taking high doses of vitamin A in combination with other potentially hepatotoxic drugs might increase the risk of liver disease.
The tolerable upper intake level (UL) is the highest level of intake that is likely to pose no risk of adverse effects. Doses of vitamin A above the UL can cause hepatotoxicity, ranging from elevated liver enzymes to liver failure.
Tetracycline Antibiotics
Theoretically, taking tetracycline antibiotics with high doses of vitamin A can increase the risk of pseudotumor cerebri.
Benign intracranial hypertension (pseudotumor cerebri) can occur with tetracyclines and with acute or chronic vitamin A toxicity. Case reports suggest that taking tetracyclines and vitamin A concurrently can increase the risk of this condition. Avoid high doses of vitamin A in people taking tetracyclines chronically.
Warfarin (Coumadin)
Theoretically, high doses of vitamin A could increase the risk of bleeding with warfarin.
Vitamin A toxicity is associated with hemorrhage and hypoprothrombinemia, possibly due to vitamin K antagonism. Advise patients taking warfarin to avoid doses of vitamin A above the tolerable upper intake level of 10,000 IU/day for adults.
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.
