HelloPharmacist Scorecard of Antarctic Krill Oil 1000 mg with Astaxanthin by Futurebiotics

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
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.
  • “Total Omega-3 Fatty Acids” is listed as a grouped ingredient — the label gives one combined amount (200 mg) without saying how much of each component you get.
  • “Antarctic Krill Oil” is listed as a grouped ingredient — the label gives one combined amount (1,000 mg) without saying how much of each component you get.

Antarctic Krill Oil 1000 mg with Astaxanthin contains four active ingredients: eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), phospholipids, and astaxanthin. EPA and DHA are omega-3 fatty acids found naturally in krill oil.

Astaxanthin is a carotenoid pigment from the krill itself that acts as an antioxidant. The product also contains gelatin, glycerine, purified water, and ethyl vanillin as inactive ingredients to hold the softgel together and preserve taste.

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: cardiovascular and brain function, joint health.
  • We looked for evidence on: Cardiovascular disease (CVD), Hypertension, Hyperlipidemia, Hypertriglyceridemia, Heart failure, Stroke — 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 Heart failure, Hyperlipidemia, Hypertension, Osteoarthritis, and more.

The evidence for astaxanthin—the ingredient we have data on—doesn't yet support its use for age-related cognitive decline, macular degeneration (eyesight loss related to aging), aging skin, Alzheimer disease, athletic performance, or carpal tunnel syndrome. The rating for all of these is insufficient reliable evidence.

We don't hold effectiveness information for the three krill-oil components (EPA, DHA, and phospholipids) in this product's facts.

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 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 from oral use are abdominal pain, diarrhea, and red-colored stools.

At the standard dose of 6 mg daily, a small number of trial participants reported increased bowel movements and red stools; at much higher doses (40 mg daily), severe stomach pain has been reported in a small number of cases. There isn't enough safety data on astaxanthin to know whether it's safe in pregnancy or while breastfeeding.

The safety data we hold advises against use during pregnancy and lactation. For the three other active ingredients (EPA, DHA, and phospholipids), pregnancy and breastfeeding safety information is not on file—talk with your doctor or pharmacist about these if you're pregnant or nursing.

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, double-check with your doctor or pharmacist if you take any medications metabolized by your liver's CYP3A4 or CYP2B6 enzyme systems (Moderate-severity interactions). These include many heart rhythm drugs, immunosuppressants, some antihistamines, and certain psychiatric medications.

We couldn't check the three krill-oil components for drug interactions, so there may be additional concerns we're not aware of.

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 product is for people interested in omega-3 supplementation with astaxanthin, but the evidence for astaxanthin's effectiveness for specific health claims isn't yet established. Before you start, check your medications with your own doctor or pharmacist—especially any for heart rhythm, transplant rejection, or mood—because astaxanthin may lower their levels.

If you're pregnant, breastfeeding, or take multiple medications, a conversation with your pharmacist is a good idea.

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

Antarctic Krill Oil2 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.

Antarctic Krill Oil 1000 mg with Astaxanthin by Futurebiotics: Common Questions

Does Antarctic Krill Oil 1000 mg with Astaxanthin by Futurebiotics interact with any medications?
Yes. Based on its ingredients, Antarctic Krill Oil 1000 mg with Astaxanthin 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 1000 mg with Astaxanthin contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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.
What does astaxanthin do in this product?
Astaxanthin is a pigment from the krill that works as an antioxidant. The product also includes EPA and DHA, omega-3 fatty acids naturally found in krill oil.
Will this help with my eyesight or brain health as I age?
The evidence for astaxanthin—the ingredient we have data on—isn't yet solid enough to recommend it for age-related eyesight loss, cognitive decline, or Alzheimer disease. More research is needed.
What side effects might I notice?
The most common ones are abdominal pain, diarrhea, and red-colored stools. At typical doses, these are uncommon; at much higher doses, severe stomach pain has been reported in a small number of people.
Is it safe to take while pregnant or breastfeeding?
There isn't enough safety data on astaxanthin to know it's safe in pregnancy or while breastfeeding, so it's best to avoid it during those times. Talk with your doctor or pharmacist for personalized advice.
Why does my stool sometimes turn red after taking this?
Red-colored stools are a documented side effect of astaxanthin, likely because of the pigment itself. It's harmless and not the same as blood in the stool, but if you're concerned, check with your pharmacist.
