HelloPharmacist Scorecard of Dynamic Krill Oil 1,600 mg by Stonehenge 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 Jul 11, 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 5 of its 5 active ingredients.
  • “Total Omega” is listed as a grouped ingredient — the label gives one combined amount (320 mg) without saying how much of each component you get.

This product contains five active ingredients. Eicosapentaenoic acid and docosahexaenoic acid are omega-3 fatty acids extracted from krill.

Astaxanthin is a natural carotenoid (a type of antioxidant) that gives krill and other seafood their color. Phospholipids and a proprietary krill oil blend (K-REAL) round out the formula.

The inactive ingredients are gelatin (the capsule), glycerin, purified water, and natural lemon oil.

Does it work?

Insufficient evidence
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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Heart health and omega-3 support.
  • We looked for evidence on: Cardiovascular disease (CVD), Hyperlipidemia, Hypertriglyceridemia, Heart failure, Hypertension, Stroke — and 2 related terms.
  • The closest evidence on file: Astaxanthin is rated "Insufficient Reliable Evidence To Rate" for Heart failure (Natural Medicines).
  • Also on file: Astaxanthin is rated "Insufficient Reliable Evidence To Rate" for Hyperlipidemia, Hypertension, Stroke.
  • Also on file: Krill Oil is rated "Insufficient Reliable Evidence To Rate" for Cardiovascular disease (CVD), Hyperlipidemia, Hypertension.

The evidence for astaxanthin is incomplete — we hold ratings of Insufficient Reliable Evidence for age-related cognitive decline, macular degeneration, aging skin, Alzheimer disease, athletic performance, and carpal tunnel syndrome. Krill oil shows more promise: it's rated Possibly Effective for dry eye.

For other uses like aging skin, Alzheimer disease, cancer, high cholesterol, and cognitive function, the evidence we hold is rated Insufficient. Talk to your pharmacist about what you're hoping this supplement will do.

The evidence, ingredient by ingredient Astaxanthin 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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Krill oil is generally well tolerated at doses up to 4 grams daily. The most common side effects are mild gastrointestinal ones — bloating, decreased appetite, diarrhea, fishy burps, flatulence, heartburn, nausea, and stomach discomfort.

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

Astaxanthin is also generally well tolerated, though abdominal pain, diarrhea, and red-colored stool have been reported; higher doses caused severe stomach pain in a small number of trial participants. One caution: avoid krill oil if you have a shellfish allergy, and use caution if you have a bleeding disorder.

For pregnancy and breastfeeding, there isn't enough data to know either way — talk with your doctor or pharmacist for personalized advice before taking this product.

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?
  • 2 of the 2 matched ingredients can interact with medications — Astaxanthin, Krill Oil.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 839 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.

Before starting, check with your pharmacist if you take blood thinners or antiplatelet drugs (like warfarin or aspirin) — krill oil may increase bleeding risk. If you're on diabetes medications, watch for signs of low blood sugar.

Also flag any medications metabolized by the liver enzymes CYP3A4 or CYP2B6, since astaxanthin may theoretically reduce their levels, though this hasn't been proven in humans. If you have a shellfish allergy, avoid this product entirely.

Check your own medication Run your meds through the checker above

The bottom line

Scorecard at a glanceFully disclosed formula with insufficient evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This is a reasonable choice if you're interested in omega-3 support and want to double-check it with your blood thinners, diabetes medications, or any drugs your liver metabolizes heavily. If you have a shellfish allergy or bleeding disorder, krill oil isn't for you.

Run your exact medications through our checker to make sure they're in the clear.

Astaxanthin2 drug types · 671 drugs

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.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, astaxanthin may decrease levels of drugs metabolized by CYP3A4.

Astaxanthin full monograph & interactions

K-REAL2 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.

How can one product interact with so many drugs?

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.
Can I take this if I'm pregnant or breastfeeding?
There isn't enough safety data on krill oil or astaxanthin to know either way during pregnancy or breastfeeding. Talk with your doctor or pharmacist before starting — they can weigh the pros and cons for your specific situation.
Does this actually work for dry eyes?
Krill oil is rated Possibly Effective for dry eye, which means there's some evidence it may help. For other conditions listed on the label, the evidence we hold is incomplete, so talk with your pharmacist about realistic expectations for what you're hoping it'll do.
What if I get stomach upset from it?
Mild gastrointestinal side effects like bloating, diarrhea, and nausea are common, especially at first. These tend to happen less often with krill oil than with fish oil. If they persist or get severe, stop and talk to your pharmacist.
I have a shellfish allergy — is this safe?
No. Krill are tiny shellfish, so you should avoid this product entirely if you have a shellfish allergy.
How many active ingredients are in this?

If I take this, will it make my blood thinner?
Krill oil contains omega-3 fatty acids that may theoretically reduce how sticky your blood cells are, which is why it can interact with blood thinners and raise bleeding risk. This is Moderate severity. Don't skip your blood thinner — just check with your pharmacist before adding this supplement.
