Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 6 of its 6 active ingredients.
  • “Omega-3 Fatty Acids” is listed as a grouped ingredient — the label gives one combined amount (420 mg) without saying how much of each component you get.
  • “Enriched NKO Krill and Fish Oil Omega-3 Blend” is a proprietary blend — the label gives one combined amount (1,000 mg) without saying how much of each component you get.

Krill Omega 50+ contains 6 active ingredients. The main ones are omega-3 fatty acids—including eicosapentaenoic acid and docosahexaenoic acid—from krill and fish oil, which are the long-chain omega-3s your body uses for heart and brain health.

The product also includes vitamin D, which supports bone and immune function; natural astaxanthin, a carotenoid antioxidant; other omega-3 fatty acids; and phospholipids that help your cells absorb these nutrients. The softgel capsule itself contains gelatin, glycerin, and purified water as inactive ingredients, along with preservatives and natural flavors.

Does it work?

Moderate 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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: brain health, joint function and cardiovascular support.
  • We looked for evidence on: Age-related cognitive decline, Alzheimer disease, Cardiovascular disease (CVD), Cognitive function, Cognitive impairment, Coronary heart disease (CHD) — and 4 related terms.
  • The strongest evidence on file: Vitamin D is rated "Possibly Effective" for Heart failure (Natural Medicines).
  • Also on file: Vitamin D is rated "Possibly Ineffective" for Cardiovascular disease (CVD).
  • Also on file: Vitamin D is rated "Insufficient Reliable Evidence To Rate" for Age-related cognitive decline, Alzheimer disease, Cognitive function, Cognitive impairment, and more.

Vitamin D in this product is effective for treating rickets, osteomalacia (soft bones), renal bone disease, hypoparathyroidism, and familial hypophosphatemia—conditions where vitamin D deficiency or metabolism is the root problem. 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.

The omega-3 fatty acids in krill oil are well studied for heart health, but that effectiveness data isn't included in the product facts we have on file.

The evidence, ingredient by ingredient Vitamin D Docosahexaenoic Acid (dha) 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 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.

Vitamin D is generally well tolerated at recommended doses, but very high doses over time can cause toxicity with symptoms of high blood calcium levels. The safety data show it's likely safe during pregnancy at recommended amounts and likely safe while breastfeeding, though you should use it only under your doctor's guidance during pregnancy.

Astaxanthin is generally well tolerated in studies, but long-term safety data are limited, and there isn't enough safety data to recommend it during pregnancy or while breastfeeding. The most common side effects of astaxanthin are abdominal pain, diarrhea, and red-colored stools; at very high doses, severe stomach pain has been reported in a small number of cases.

Side effects, ingredient by ingredient Vitamin D Docosahexaenoic Acid (dha) Astaxanthin

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 — Vitamin D, Astaxanthin.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: heart-rhythm medications.
  • For scale: 744 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're on heart rhythm medications (verapamil, diltiazem, digoxin), thiazide diuretics, atorvastatin, the psoriasis medication calcipotriene, or any drug metabolized through the CYP3A4 or CYP2B6 enzyme pathways in your liver. Vitamin D at high doses can raise blood calcium dangerously with some of these drugs, and astaxanthin may theoretically slow how your liver processes others.

For each ingredient in Krill Omega 50+ with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Vitamin D8 drug types · 715 drugs

Aluminum

Vitamin D might increase aluminum absorption and toxicity, but this has only been reported in people with renal failure.
The protein that transports calcium across the intestinal wall can also bind and transport aluminum. This protein is stimulated by vitamin D, which may therefore increase aluminum absorption. This mechanism may contribute to increased aluminum levels and toxicity in people with renal failure, when they take vitamin D and aluminum-containing phosphate binders chronically.

Likelihood Probable Evidence B
Atorvastatin (Lipitor)

Vitamin D might reduce absorption of atorvastatin.
A small, low-quality clinical study shows that taking vitamin D reduces levels of atorvastatin and its active metabolites by up to 55%. However, while atorvastatin levels decreased, total cholesterol, low-density lipoprotein (LDL) cholesterol, and high-density lipoprotein (HDL) cholesterol levels did not substantially change. Atorvastatin is metabolized in the gut by CYP3A4 enzymes, and researchers theorized that vitamin D might induce CYP3A4, causing reduced levels of atorvastatin. However, this proposed mechanism was not specifically studied.

Likelihood Probable Evidence B
Calcipotriene (Dovonex)

Taking calcipotriene with vitamin D increases the risk for hypercalcemia.
Calcipotriene is a vitamin D analog used topically for psoriasis. It can be absorbed in sufficient amounts to cause systemic effects, including hypercalcemia. Theoretically, combining calcipotriene with vitamin D supplements might increase the risk of hypercalcemia.

Likelihood Probable Evidence D
Digoxin (Lanoxin)

Theoretically, hypercalcemia induced by high-dose vitamin D can increase the risk of arrhythmia from digoxin.
High doses of vitamin D can cause hypercalcemia. Hypercalcemia increases the risk of fatal cardiac arrhythmias with digoxin. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and digoxin concurrently.

Likelihood Possible Evidence D
Diltiazem (Cardizem, Others)

Theoretically, hypercalcemia induced by high-dose vitamin D can reduce the therapeutic effects of diltiazem for arrhythmia.
High doses of vitamin D can cause hypercalcemia. Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation. Theoretically this could also occur with diltiazem. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and diltiazem concurrently.

Likelihood Probable Evidence B
Thiazide Diuretics

Theoretically, taking thiazide diuretics and high-dose vitamin D can increase the risk of hypercalcemia.
Thiazide diuretics decrease urinary calcium excretion, which could lead to hypercalcemia if vitamin D supplements are taken concurrently. This has been reported in people being treated with vitamin D for hypoparathyroidism, and also in elderly people with normal parathyroid function who were taking a thiazide, vitamin D, and calcium-containing antacids daily.

Likelihood Probable Evidence D
Verapamil (Calan, Others)

Hypercalcemia induced by high-dose vitamin D can reduce the therapeutic effects of verapamil for arrhythmia.
Hypercalcemia due to high doses of vitamin D can reduce the effectiveness of verapamil in atrial fibrillation. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and verapamil concurrently.

Likelihood Probable Evidence B
Cytochrome P450 3A4 (Cyp3A4) Substrates

Vitamin D might induce CYP3A4 enzymes and reduce the bioavailability of CYP3A4 substrates.
There is some concern that vitamin D might induce CYP3A4. In vitro research suggests that vitamin D induces CYP3A4 transcription. Additionally, observational research has found that increased UV light exposure and serum vitamin D levels are associated with decreased serum levels of CYP3A4 substrates such as tacrolimus and sirolimus, while no association between UV light exposure or vitamin D levels and levels of mycophenolic acid, a non-CYP3A4 substrate, was found. A small, low-quality clinical study shows that taking vitamin D reduces levels of the CYP3A4 substrate atorvastatin and its active metabolites by up to 55%; however, the clinical effects of atorvastatin were not reduced. While researchers theorized that vitamin D might induce CYP3A4, this proposed mechanism was not specifically studied.

natural 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.

Omega-3 Fatty Acids3 drug types · 375 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, DHA may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Although some clinical evidence suggests that DHA might reduce collagen-stimulated platelet aggregation and thromboxane release, most clinical evidence suggests that DHA alone does not affect blood clotting. However, theoretically, when given in combination with EPA as fish oil, concomitant use with anticoagulant or antiplatelet drugs (including aspirin) might increase risk of bleeding.

Likelihood Unlikely Evidence B
Antidiabetes Drugs

Theoretically, taking DHA with antidiabetes drugs might reduce the effects of these medications.
In people with type 2 diabetes, including those taking oral hypoglycemic medications, DHA seems to increase fasting blood glucose levels.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, taking DHA with antihypertensive drugs might increase the risk of hypotension.
Fish oils containing DHA can lower blood pressure and might have additive effects in patients treated with antihypertensives; use with caution.

Krill Omega 50+ by Purity Products: Common Questions

Does Krill Omega 50+ by Purity Products interact with any medications?
Yes. Based on its ingredients, Krill Omega 50+ has a known interaction with 990 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Krill Omega 50+ contains 4 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.
Is it safe to take this during pregnancy?
Vitamin D in this product is likely safe at recommended doses during pregnancy, though you should only take it under your doctor's guidance. Astaxanthin, however, doesn't have enough safety data in pregnancy—the data advise against it. Talk with your doctor before starting this product if you're pregnant or planning to be, so they can help you decide whether the vitamin D is worth it for your situation.
Is it safe while breastfeeding?
Vitamin D is likely safe while breastfeeding at recommended doses. Astaxanthin doesn't have enough safety data to recommend it while breastfeeding, so it's best avoided during that time. Check with your doctor or pharmacist if you want to breastfeed and take this product.
What does vitamin D do in this supplement?
Vitamin D supports bone health and is effective for treating rickets, soft bones, kidney bone disease, and parathyroid disorders where vitamin D metabolism is the problem. At recommended doses, it's generally well tolerated, though very high doses over time can cause vitamin D toxicity.
What's astaxanthin and why is it in here?
Astaxanthin is a natural carotenoid—a reddish pigment from krill and other sea organisms—added for its antioxidant properties. The evidence in our data is insufficient to rate how well it works for aging skin, eye health, or cognitive decline, so we don't know yet whether it delivers the benefits the marketing claims.
Will this cause red stools?
Red or orange-colored stools can happen with astaxanthin because of the pigment itself, not a medical problem. A small number of trial participants taking astaxanthin experienced this along with increased bowel movements or abdominal pain. It's generally harmless, but if it bothers you or you have severe stomach pain, talk with your pharmacist.
