HelloPharmacist Scorecard of Krill Oil by DaVinci Laboratories
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 krill oil softgel has 3 active ingredients. The main ones are omega-3 fatty acids — specifically eicosapentaenoic acid and docosahexaenoic acid, the types your body uses for heart and brain health — plus phospholipids, which help your cells absorb those fatty acids.
It also contains astaxanthin, a red pigment from krill that acts as an antioxidant. The capsule itself is made from gelatin, glycerin, purified water, and sorbitol.
Does it work?
Couldn't assess
The evidence we hold rates all the uses we have data for — cognitive decline with aging, macular degeneration, aging skin, Alzheimer disease, athletic performance, and carpal tunnel syndrome — as having insufficient reliable evidence. That means the studies so far haven't been strong enough to say whether astaxanthin works for any of these.
We don't have effectiveness ratings on file for the omega-3 components or phospholipids in this product.
How safe is it?
Well-documented data
Astaxanthin is generally well tolerated in studies, but long-term safety data are limited. The most common side effects reported are abdominal pain, diarrhea, and red-colored stools — a harmless discoloration from the astaxanthin itself.
At the standard 6 mg dose, a small number of people reported increased bowel movements and red stools; at higher doses (40 mg), a small number experienced severe stomach pain. There isn't enough safety data for astaxanthin during pregnancy or while breastfeeding, so it's best to avoid it in both cases.
We don't have pregnancy or breastfeeding safety information on file for the omega-3 fatty acids or phospholipids. If you're pregnant, planning to become pregnant, or breastfeeding, talk with your doctor or pharmacist before taking this product.
Meds to double-check
Moderate interaction found
Before you start, double-check any drugs your liver metabolizes — especially those processed through the CYP3A4 or CYP2B6 pathways (your pharmacist can tell you if yours are). Astaxanthin might lower their levels, making them less effective.
Altogether, these interactions span 672 individual medications, so it's worth confirming your specific prescriptions aren't in that group.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
Krill oil may work well if you're looking for omega-3 fatty acids, but the evidence for astaxanthin's benefits isn't solid yet. The main caution is that astaxanthin might slow down how your liver clears certain medications, though this hasn't been proven in humans — if you take prescription drugs, especially ones that involve liver metabolism, check with your doctor or pharmacist first.
Skip it if you're pregnant or breastfeeding until you've talked it over with your healthcare provider.

Krill Oil by DaVinci Laboratories Drug Interactions
HelloPharmacist Interaction Report
Krill Oil by DaVinci Laboratories contains astaxanthin, which may interact with medications metabolized by your liver's CYP3A4 and CYP2B6 enzymes — potentially lowering their blood levels.
The product also contains omega-3 fatty acids (eicosapentaenoic acid and docosahexaenoic acid) and phospholipids, but we cannot check those ingredients for interactions. Altogether, these interactions span 672 individual medications.
Read the full breakdown — every affected drug type, severity by severity
The main concern is astaxanthin's theoretical ability to speed up how your liver breaks down certain drugs. In lab studies, astaxanthin boosted activity of CYP3A4 and CYP2B6 enzymes, but this effect hasn't been confirmed in actual humans yet — so it remains a theoretical risk, not a proven one.
Both are rated Moderate severity.
Because we hold no interaction data for the omega-3 components and phospholipids in this product, we can't rule out effects from those either. If you take any prescription medication, especially anything your doctor said your liver processes, run your exact drug names through the checker below before starting krill oil.

NKO
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.
