HelloPharmacist Scorecard of Odorless Krill Oil 500 mg by Natrol

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 7 of its 7 active ingredients.
  • “Total Omega-3 Fatty Acids” is listed as a grouped ingredient — the label gives one combined amount (110 mg) without saying how much of each component you get.
  • “Superba Krill Oil” is listed as a grouped ingredient — the label gives one combined amount (500 mg) without saying how much of each component you get.

Natrol's Odorless Krill Oil contains 7 active ingredients: three fatty acids (eicosapentaenoic acid and docosahexaenoic acid, which are omega-3s, plus omega-6 and omega-9 fatty acids), phospholipids, choline, and astaxanthin, delivered in a base of krill oil. The product also contains inactive ingredients — gelatin, glycerin, and water — that serve as the capsule and vehicle.

Krill oil is a concentrated source of omega-3 fatty acids and phospholipids. Choline supports brain function and other body processes.

Astaxanthin is a carotenoid antioxidant found in marine organisms.

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: support for healthy cholesterol within normal range.
  • We looked for evidence on: Cardiovascular disease (CVD), Hyperlipidemia, Hypertriglyceridemia, Heart failure, coronary heart disease, dyslipidemia — and 1 related terms.
  • The closest evidence on file: Omega-6 Fatty Acids is rated "Possibly Ineffective" for Cardiovascular disease (CVD) (Natural Medicines).
  • Also on file: Omega-6 Fatty Acids is rated "Possibly Ineffective" for Hyperlipidemia.
  • Also on file: Choline is rated "Insufficient Reliable Evidence To Rate" for Cardiovascular disease (CVD).

The evidence for what this product does is thin. We hold no effectiveness ratings for krill oil itself, the main omega-3 fatty acids it contains, or phospholipids.

Choline has been studied for athletic performance (possibly ineffective), age-related cognitive decline, Alzheimer disease, hay fever, bronchitis, and liver damage from parenteral nutrition — but the evidence is either insufficient or points to it not working. Astaxanthin has been studied for similar conditions — cognitive decline, macular degeneration, aging skin, Alzheimer disease, athletic performance, and carpal tunnel — and again the evidence is insufficient for most claims.

Omega-6 fatty acids appear possibly ineffective for lowering cholesterol (hyperlipidemia), heart disease, and multiple sclerosis.

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Choline is generally well tolerated at food-level amounts and likely safe in pregnancy and while breastfeeding, though you should use supplement doses only as your doctor advises during those periods. At doses above 3.5 grams daily, choline can cause fishy body odor, and at very high doses (9 grams or more) it may cause diarrhea, nausea, sweating, and vomiting.

Astaxanthin appears well tolerated in studies, though long-term safety data are limited. In trial doses, it has caused abdominal pain, diarrhea, and red-colored stools in some participants.

The safety notes advise against astaxanthin during pregnancy and while breastfeeding because there isn't enough data to know if it's safe. Omega-6 from normal food is fine, but supplements of it are less well established in safety.

The data notes that a high ratio of omega-6 to omega-3 in your diet may increase heart disease risk and that high omega-6 levels have been linked to depression and some cancers in population studies — talk with your doctor before starting, especially if you have heart disease.

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 3 matched ingredients can interact with medications — Choline, Astaxanthin.
  • The most serious interaction on file is rated Moderate.
  • For scale: 682 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.

Check with your doctor or pharmacist before taking this product if you take atropine (a drug sometimes used for eye exams or certain other conditions) — choline may reduce how it works. Additionally, if you take any medication broken down by your liver through the CYP3A4 or CYP2B6 pathways (a large number of common drugs), astaxanthin may theoretically lower its levels, though this has not been proven in humans.

Use the medication search tool on this page to verify your specific drugs.

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 product is a source of omega-3 and other fatty acids, but the evidence that it works for any specific condition is not established in our data. The main safety concern is that we could not check the core fatty acid ingredients for drug interactions, and the liver-enzyme interactions from astaxanthin could affect many medications.

Before starting, search your exact medications in the tool on this page, and talk with your doctor or pharmacist — particularly if you take drugs processed through your liver, manage heart disease, or are pregnant or breastfeeding.

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.

Odorless Krill Oil 500 mg by Natrol: Common Questions

Does Odorless Krill Oil 500 mg by Natrol interact with any medications?
Yes. Based on its ingredients, Odorless Krill Oil 500 mg has a known interaction with 848 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Odorless Krill Oil 500 mg contains 2 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 is krill oil and why is it in this product?
Krill oil comes from tiny shrimp-like sea animals and is a natural source of omega-3 fatty acids (eicosapentaenoic acid and docosahexaenoic acid) and phospholipids. It's included because these are nutrients some people want to add to their diet, though evidence that this product works for a specific health condition is not established.
Is it safe to take this while I'm pregnant?
Choline in this product is likely safe in pregnancy, but astaxanthin — another ingredient — does not have enough safety data, and the facts advise against it during pregnancy. Talk with your doctor before taking this product while you're pregnant, as they can weigh all the ingredients for your situation.
Is it safe to take while breastfeeding?
Choline is likely safe while breastfeeding; in fact, choline needs are higher during breastfeeding and supplements should be used only under professional guidance. However, astaxanthin does not have enough safety data, and the facts advise against it while breastfeeding. Speak with your doctor or pharmacist before starting.
Can this cause side effects?
Astaxanthin may cause abdominal pain, diarrhea, or red-colored stools in some people. Choline is well tolerated at normal doses, but high doses (over 3.5 grams daily) can cause fishy body odor, and very high doses can cause nausea, vomiting, and diarrhea.
Why is it 'odorless'?
Regular krill oil can have a fishy smell. This version is processed to remove that odor while keeping the active ingredients, so it's easier to take without the taste or smell.
Will this help my cholesterol or heart health?
The evidence in our data does not support that omega-6 fatty acids (which this product contains) work for cholesterol or heart disease. We hold no effectiveness ratings for the krill oil or its main omega-3 components. Talk with your doctor about whether this is right for your specific health goals.
