HelloPharmacist Scorecard of Ultimate Krill Omega-3 by ProCaps 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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Sep 24, 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 7 of its 7 active ingredients.
  • “Total Omega-3 Fatty Acids” is listed as a grouped ingredient — the label gives one combined amount (400 mg) without saying how much of each component you get.

Ultimate Krill Omega-3 contains 7 active ingredients centered on omega-3 fatty acids from Antarctic krill oil. The main omega-3 components are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), plus astaxanthin, a carotenoid antioxidant naturally found in krill.

The product also includes phospholipids (fat-like compounds in cell membranes) and a proprietary orange essence flavoring. The capsule itself is a soft-gelatin shell, the only inactive ingredient listed.

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.

Why this rating?
  • The label markets this product for: Phospholipid-based omega-3 support for heart and brain.
  • We looked for evidence on: Cardiovascular disease (CVD), Hyperlipidemia, Hypertriglyceridemia, Age-related cognitive decline, Cognitive function, cholesterol support — and 1 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 Hyperlipidemia.
  • Also on file: Krill Oil is rated "Insufficient Reliable Evidence To Rate" for Cardiovascular disease (CVD), Cognitive function, Hyperlipidemia, Hypertriglyceridemia.

Krill oil is rated possibly effective for dry eye symptoms based on available evidence. For astaxanthin, the evidence we hold is insufficient to rate its effectiveness for age-related cognitive decline, macular degeneration, aging skin, Alzheimer's disease, athletic performance, or carpal tunnel syndrome.

Krill oil also has insufficient evidence for aging skin, Alzheimer's disease, cancer prevention, high cholesterol (hyperlipidemia), and cognitive function. The data on these uses isn't established well enough for us to say whether this product will work for you.

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.

Both astaxanthin and krill oil are generally well tolerated, though long-term safety data for astaxanthin are limited. The most common side effects from krill oil are digestive — bloating, diarrhea, nausea, heartburn, fishy burps, and stomach discomfort.

Astaxanthin may cause abdominal pain, diarrhea, and red-colored stools; at higher doses, severe stomach pain has been reported in a small number of trial participants. Headache, tiredness, and dizziness have been reported rarely with krill oil.

If you have a shellfish allergy, avoid this product — krill oil comes from crustaceans. If you have a bleeding disorder, use caution.

For pregnancy and breastfeeding, there isn't enough safety data to know either way; talk with your doctor or pharmacist for personalized advice.

Side effects, ingredient by ingredient Astaxanthin Krill Oil

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 taking this product, check with your doctor or pharmacist if you take anticoagulant or antiplatelet drugs (blood thinners like warfarin, clopidogrel, or aspirin) — krill oil may increase bleeding risk. Also double-check if you take antidiabetes medications, since krill oil may theoretically lower blood sugar.

Additionally, if you take medications broken down by your liver (especially those processed by CYP3A4 or CYP2B6 enzymes), astaxanthin may theoretically reduce their effectiveness — your pharmacist can identify these for you.

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.

All-Solar Manufacturing

Antarctic Krill are tiny, shrimp-like creatures that live in the oceans near Antarctica and represent one of the most abundant life forms on the planet. Krill Oil provides a unique source of the most important Omege-3 fatty acids EPA and DHA, but in a distinctive and highly absorbable phospholipid form. Another bonus: Krill Oil’s rich reddish color comes from the presence of trace amounts of the protective carotenoids Astaxanthin. Omega-3s are absolutely essential for our good health, yet they cannot be made by the body, so their benefits are only available from cold water fish or an Omega-3 dietary supplement. Research has shown that diets rich in Omega-3s are associated with superior heart, brain, circulatory and general health; yet sadly, the American diet delivers alarmingly low levels of these precious fatty acids.

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

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.
