HelloPharmacist Scorecard of Krill Oil by Village Vitality
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
Village Vitality Krill Oil is a 6-ingredient softgel with krill oil as its foundation, supplemented by astaxanthin. The product contains three omega-3 fatty acids — eicosapentaenoic acid, docosahexaenoic acid, and total omega-3 fatty acids — which are the active compounds that give krill oil its nutritional profile.
Astaxanthin is a carotenoid antioxidant also derived from krill. The remaining ingredients — gelatin, glycerin, and water — are inactive excipients that form the capsule and help with absorption.
Does it work?
Moderate evidence
The evidence for krill oil varies widely by condition. It's rated possibly effective for dry eye, which is the strongest data available for this product.
For aging skin, Alzheimer disease, cancer, high cholesterol (hyperlipidemia), and cognitive function, the evidence isn't yet established in the data we hold — there simply isn't enough reliable research to rate it one way or another. Talk with your doctor about what krill oil might realistically do for your specific concern.
How safe is it?
Well-documented data
Krill oil is generally well tolerated in doses up to 4 grams daily. The most common side effects are gastrointestinal — bloating, decreased appetite, diarrhea, fishy burps, flatulence, heartburn, nausea, and stomach discomfort — though these tend to be milder or happen less often with krill oil than with fish oil.
Headache, tiredness, and dizziness have been reported rarely. You should avoid this product if you have a shellfish allergy and use caution if you have a bleeding disorder.
There isn't enough safety data to know whether krill oil is safe during pregnancy or breastfeeding — talk with your doctor or pharmacist before using it if you're pregnant or nursing. Astaxanthin carries similar cautions: it's generally well tolerated in studies, but long-term safety data are limited, and the safety data advise against use during pregnancy and breastfeeding.
Meds to double-check
Moderate interaction found
Check with your doctor or pharmacist before taking this product if you use anticoagulants or antiplatelet drugs (blood thinners like warfarin or aspirin) — krill oil may theoretically raise bleeding risk. If you take diabetes medications, confirm it's okay first, since krill oil might theoretically lower blood sugar, though evidence is mixed.
Also verify any medications you take that are broken down by your liver's CYP3A4 or CYP2B6 enzymes — astaxanthin may theoretically slow their breakdown and raise their levels.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
If you have dry eye and no blood clotting disorders or diabetes, krill oil is worth discussing with your doctor. If you take blood thinners, diabetes medications, or drugs broken down by your liver's CYP3A4 or CYP2B6 systems, you'll need to check with your own doctor or pharmacist before starting — the interactions are theoretical but documented.
Gastrointestinal side effects are common but usually mild. It's not recommended in pregnancy or breastfeeding without a conversation with your healthcare provider first.

Krill Oil by Village Vitality Drug Interactions
HelloPharmacist Interaction Report
Village Vitality Krill Oil has documented interactions with blood thinners and diabetes medications, primarily through its krill oil and astaxanthin content.
The most serious concern is a Moderate-severity risk with anticoagulants and antiplatelet drugs — krill oil's omega-3 fatty acids may theoretically increase bleeding risk if combined with these medications. Additionally, krill oil may theoretically raise the risk of low blood sugar (hypoglycemia) if you're taking diabetes drugs, though the evidence here is mixed and a small study found no effect on blood glucose in people with type 2 diabetes.
Read the full breakdown — every affected drug type, severity by severity
Astaxanthin in this product may theoretically slow how your liver breaks down certain medications metabolized by the CYP3A4 and CYP2B6 enzyme systems, potentially raising their levels in your bloodstream. This is a Moderate-severity theoretical concern documented only in lab research so far, not yet reported in people.
We could not check three other ingredients — eicosapentaenoic acid, docosahexaenoic acid, and phospholipids — because we hold no interaction data for them. Altogether, these interactions span 839 individual medications.

For each ingredient in 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.
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.
