HelloPharmacist Scorecard of Antarctic Krill Oil 2000 mg by Bronson

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.

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 4 of its 4 active ingredients.
  • “Antarctic Krill Oil” is listed as a grouped ingredient — the label gives one combined amount (2,000 mg) without saying how much of each component you get.
  • “Total Omega 3 Fatty Acids” is listed as a grouped ingredient — the label gives one combined amount (120 mg) without saying how much of each component you get.

Antarctic Krill Oil 2000 mg delivers 4 active ingredients per softgel. Astaxanthin is a natural pigment with antioxidant properties.

The product also contains eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are omega-3 fatty acids found in krill, plus phospholipids that help your body absorb them. The capsule itself is made from gelatin, glycerin, purified water, and ethyl vanillin — these are inactive ingredients that give the softgel its form.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Astaxanthin's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: heart, joint and brain health.
  • We looked for evidence on: Cardiovascular disease (CVD), Hypertriglyceridemia, Hyperlipidemia, Osteoarthritis, Rheumatoid arthritis (RA), Age-related cognitive decline — and 4 related terms.
  • The closest evidence on file: Astaxanthin is rated "Insufficient Reliable Evidence To Rate" for Age-related cognitive decline (Natural Medicines).
  • Also on file: Astaxanthin is rated "Insufficient Reliable Evidence To Rate" for Age-related macular degeneration (AMD), Dry eye, Hyperlipidemia, Osteoarthritis, and more.

The evidence we hold shows insufficient reliable data to rate astaxanthin for age-related cognitive decline, age-related macular degeneration, aging skin, Alzheimer disease, athletic performance, or carpal tunnel syndrome. You won't find a strong effectiveness claim in our data for those uses, so talk with your doctor about whether this product is right for your specific goal.

The evidence, ingredient by ingredient Krill Oil Astaxanthin

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Astaxanthin is generally well tolerated in studies, though long-term safety data are limited. The most common side effects reported orally are abdominal pain, diarrhea, and red-colored stools.

A small number of trial participants taking 6 mg daily experienced increased bowel movements or red stools, while those taking higher doses (40 mg daily) reported severe stomach pain in isolated cases. There isn't enough safety data to know whether astaxanthin is safe in pregnancy or while breastfeeding.

If you're pregnant, planning to become pregnant, or nursing, talk with your doctor or pharmacist 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?
  • 1 of the 1 matched ingredient can interact with medications — Astaxanthin.
  • The most serious interaction on file is rated Moderate.
  • For scale: 672 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 taking this product, have your doctor or pharmacist double-check any medications you take that are broken down by your liver's CYP3A4 or CYP2B6 enzymes — these are listed as Moderate interactions. Common examples include certain blood pressure medications, heart rhythm drugs, cholesterol medications, and some psychiatric medications.

We also could not check the omega-3 fatty acids in this product against our database, so mention those to your healthcare provider as well.

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.

This krill oil supplement may be worth considering if you're interested in omega-3s and astaxanthin, but the effectiveness evidence for specific conditions isn't well established in our data. The main caution is that astaxanthin could theoretically lower levels of certain medications your liver processes — if you take any prescription drugs, check them with your doctor or pharmacist before starting.

Pregnant and breastfeeding individuals should avoid it until they've discussed safety with their own healthcare provider.

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.

Antarctic Krill Oil 2000 mg by Bronson: Common Questions

Does Antarctic Krill Oil 2000 mg by Bronson interact with any medications?
Yes. Based on its ingredients, Antarctic Krill Oil 2000 mg has a known interaction with 838 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Antarctic Krill Oil 2000 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
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?
Not without talking to your doctor first. There isn't enough safety data on astaxanthin during pregnancy or while breastfeeding, so the safety data advises against it. Your doctor or pharmacist can help you decide whether it's right for you.
What are EPA and DHA in this product?
EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are omega-3 fatty acids naturally found in krill. They're the main reason many people take krill oil supplements.
Why might my stools be red after taking this?
Red-colored stools are a known side effect of astaxanthin, the pigment in this product. It's not harmful — just the natural color coming through — but if it bothers you or you also develop abdominal pain or diarrhea, stop taking it and talk with your pharmacist.
Does astaxanthin actually help with memory or age-related decline?
We don't have enough reliable evidence to say whether it helps those conditions. If memory support is your main goal, ask your doctor what the research actually shows for this ingredient and whether it's right for you.
Is this product safe long-term?
Astaxanthin is generally well tolerated in short-term studies, but we don't have solid long-term safety data. If you plan to take this for months or years, check in with your doctor about whether ongoing use is appropriate for you.
