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

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 product includes eicosapentaenoic acid and docosahexaenoic acid — two omega-3s your body uses for heart and brain health — plus phospholipids that help your body absorb them.

Astaxanthin, a natural antioxidant found in krill, is also included. The softgel capsule also carries a proprietary orange essence flavoring.

The only inactive ingredient listed is the soft-gelatin capsule itself.

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 supplementation.
  • We looked for evidence on: Cardiovascular disease (CVD), Hyperlipidemia, Hypertriglyceridemia, Heart failure, Stroke, Hypertension — and 3 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.

Krill oil in this product is possibly effective for dry eye symptoms. For everything else — including aging skin, Alzheimer disease, cancer, high cholesterol, and cognitive function — the evidence we have isn't strong enough to rate.

Astaxanthin's effectiveness for age-related cognitive decline, macular degeneration, aging skin, and other conditions also lacks reliable evidence to rate, meaning studies haven't shown clear benefits yet.

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.

Antarctic Krill Oil is generally well tolerated, but skip this product if you have a shellfish allergy — krill is a shellfish product. If you have a bleeding disorder, use caution and talk to your doctor first.

Gastrointestinal side effects like bloating, diarrhea, fishy burps, heartburn, and nausea are most common, though they tend to be milder with krill oil than with fish oil. Headache, tiredness, and dizziness have been reported rarely.

Astaxanthin is also generally well tolerated, though long-term safety data are limited. Most common side effects are abdominal pain, diarrhea, and red-colored stool.

At very high doses (40 mg daily), severe stomach pain has been reported in a small number of people. For pregnancy and breastfeeding, we don't have enough safety data for either ingredient — talk with your doctor or pharmacist about whether this product is right for you before using it during pregnancy or while nursing.

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 Ultimate Krill Omega-3, check with your pharmacist if you take blood thinners or antiplatelet drugs like warfarin or aspirin (Moderate risk of increased bleeding), diabetes medications (Moderate risk of low blood sugar), or drugs broken down by your liver's CYP3A4 or CYP2B6 enzymes — a large group that includes many common medications (Moderate risk of decreased drug levels).

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

Theoretically, astaxanthin may decrease levels of drugs metabolized by CYP3A4.
In vitro research shows that astaxanthin induces CYP3A4 enzyme activity in human hepatocytes. This effect has not been reported in humans.

Likelihood Possible Evidence D

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.

Ultimate Krill Omega-3 by ProCaps Laboratories: Common Questions

Does Ultimate Krill Omega-3 by ProCaps Laboratories interact with any medications?
Yes. Based on its ingredients, Ultimate Krill Omega-3 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?
Ultimate Krill Omega-3 contains 7 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.
Does krill oil actually work for anything?
The strongest evidence we have is for dry eye — krill oil is possibly effective for that. For other conditions like high cholesterol, aging skin, and brain health, the evidence isn't established yet in our data.
Can I take this if I'm pregnant or breastfeeding?
We don't have enough safety data for krill oil or astaxanthin during pregnancy or breastfeeding. Talk with your doctor or pharmacist before using this product if you're pregnant, nursing, or planning to become pregnant — they can weigh the risks and benefits for your situation.
What side effects might I notice?
Most people tolerate krill oil well. The most common side effects are mild gastrointestinal ones: bloating, diarrhea, fishy burps, heartburn, nausea, and stomach discomfort. Headache, tiredness, and dizziness are rare. Astaxanthin may cause abdominal pain, diarrhea, or red-colored stool.
Is it safe if I have a shellfish allergy?
No. Krill is a shellfish product, so this supplement isn't appropriate for you. Talk with your pharmacist about omega-3 alternatives that don't contain shellfish.
What's astaxanthin doing in a krill oil product?
Astaxanthin is a natural antioxidant found in krill itself. It's included because it's part of the krill you're already taking, though we don't yet have strong evidence for specific benefits it provides on its own.
