HelloPharmacist Scorecard of Antarctic Krill Oil 2000 mg by Approved Science

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 5 of its 5 active ingredients.
  • “Phospholipid Omega-3 Complex” is a proprietary blend — the label gives one combined amount (680 mg) without saying how much of each component you get.
  • “Krill-Sci 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.

This product has 5 active ingredients. The main components are three omega-3 fatty acids — eicosapentaenoic acid, docosahexaenoic acid, and other fatty acids — which are the omega-3s people take krill oil for.

It also contains astaxanthin, a red pigment from krill with antioxidant properties, and phospholipids, which are fat-like compounds that help your body absorb the other ingredients. The capsule itself is made from gelatin and glycerin.

Does it work?

Couldn't assess
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 assessable

This is a single-ingredient Astaxanthin product and its label doesn't state a use — see Astaxanthin's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence we hold for astaxanthin doesn't support a firm rating for any condition. We have insufficient reliable evidence for age-related cognitive decline, age-related macular degeneration (AMD), aging skin, Alzheimer disease, athletic performance, and carpal tunnel syndrome.

We don't have effectiveness data on file for the omega-3 fatty acids in this product.

The evidence, ingredient by ingredient 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.

At standard doses (6 mg daily), a small number of trial participants experienced increased bowel movements and red fecal color; at higher doses (40 mg daily), severe stomach pain has been reported in a small number of people. There isn't enough safety data to know whether astaxanthin is safe in pregnancy, so the data advises against it during pregnancy.

The same applies to breastfeeding — talk with your pharmacist or doctor if you're pregnant or nursing and want to use 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 you take this product, check whether you're on any medications broken down by the liver enzymes CYP3A4 or CYP2B6 — astaxanthin may theoretically lower their levels. These include some blood pressure medications, certain immunosuppressants, and some cholesterol drugs.

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.

This krill oil supplement is primarily a source of omega-3 fatty acids, with added astaxanthin. If you take medications processed through your liver — especially certain blood pressure drugs, immunosuppressants, or statins — check with your pharmacist before starting.

Pregnant and breastfeeding individuals should talk to their doctor first because safety data are limited.
