HelloPharmacist Scorecard of Krill Oil Gold 1,000 mg Maximum Strength by NutriGold

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.
  • “Total Omega-3 Fatty Acids” is listed as a grouped ingredient — the label gives one combined amount (240 mg) without saying how much of each component you get.
  • “Krill Oil” is listed as a grouped ingredient — the label gives one combined amount (1,000 mg) without saying how much of each component you get.

This product contains 5 active ingredients. The main ones are eicosapentaenoic acid and docosahexaenoic acid — two omega-3 fats derived from krill oil that many people take for heart and brain support.

The product also contains phospholipids and other omega-3 fatty acids from the krill, plus esterified astaxanthin, a carotenoid (a natural pigment) that may act as an antioxidant. The softgel shell is an inactive ingredient that holds everything together.

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 — see Astaxanthin's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: supports heart, brain, joint, eye, women's health.
  • We looked for evidence on: Cardiovascular disease (CVD), Hyperlipidemia, Hypertriglyceridemia, Heart failure, Stroke, Age-related cognitive decline — and 4 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 Age-related macular degeneration (AMD), Alzheimer disease, Heart failure, Dry eye, and more.

We don't have reliable evidence in our data to rate how well astaxanthin works for age-related cognitive decline, macular degeneration, aging skin, Alzheimer's disease, athletic performance, or carpal tunnel syndrome. The product label may point you to other sources on krill oil's potential benefits, but our monograph data on astaxanthin's effectiveness in these areas is incomplete.

The evidence, ingredient by ingredient Krill Oil 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, but long-term safety data are limited. The most common side effects reported in trials were abdominal pain, diarrhea, and red-colored stools — a harmless discoloration from the astaxanthin itself.

At typical doses (around 6 mg daily), increased bowel movements and red stools appeared in a small number of participants; at much higher doses (40 mg daily), severe stomach pain was reported in a small number of cases. There isn't enough safety data to know whether astaxanthin is safe in pregnancy or while breastfeeding, so the data advises against use during pregnancy and lactation.

Talk with your doctor or pharmacist about whether this product is right for you if you're pregnant, planning to become pregnant, or nursing.

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 start this product, check with your doctor or pharmacist if you take any medications metabolized by CYP3A4 or CYP2B6 enzymes — that's a large list spanning statins, some antiarrhythmics, certain immunosuppressants, and many others. Astaxanthin may theoretically lower their blood levels, though human evidence is lacking.

We could not check the other omega-3 ingredients for drug interactions.

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.

Krill Oil Gold is an omega-3 supplement with astaxanthin that most people tolerate well, but it may theoretically interact with medications your liver breaks down — mainly CYP3A4 and CYP2B6 substrates. If you take any prescription medications, check them against this product before starting.

Pregnant women and those breastfeeding should discuss it with their doctor or pharmacist first, since safety data in those situations are limited.

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.

Krill Oil Gold 1,000 mg Maximum Strength by NutriGold: Common Questions

Does Krill Oil Gold 1,000 mg Maximum Strength by NutriGold interact with any medications?
Yes. Based on its ingredients, Krill Oil Gold 1,000 mg Maximum Strength 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?
Krill Oil Gold 1,000 mg Maximum Strength contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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's astaxanthin, and why is it in this krill oil?
Astaxanthin is a natural pigment found in krill and other marine organisms. It acts as an antioxidant — a compound that may help protect cells from damage. It's included because some people believe it supports eye health, skin, and aging, though we don't have reliable evidence to confirm these benefits yet.
Will this make my stool red or orange?
Yes, it might. Red or orange-colored stools are a harmless side effect from the astaxanthin and have been reported in studies. It's just the pigment passing through; it's not blood and doesn't mean anything is wrong.
Can I take this if I'm pregnant or breastfeeding?
No, not based on the safety data we have. There isn't enough information to know whether astaxanthin is safe during pregnancy or while breastfeeding, so the data advises against it. Talk with your doctor or pharmacist for personalized advice.
Is this product safe long-term?
Astaxanthin is generally well tolerated in studies, but long-term safety data are limited. For ongoing use beyond what's been studied, talk with your doctor or pharmacist about whether it's right for you.
What if I have stomach pain after taking it?
Mild abdominal pain was reported by some people in trials, but severe stomach pain appeared at very high doses (40 mg daily — much higher than a typical supplement). If you experience any pain after starting, stop taking it and talk with your pharmacist or doctor.
Why do you say there are 672 interactions if the product only has a few ingredients?
Astaxanthin can theoretically interact with a large number of individual medications that your liver breaks down — over 600 of them. Each drug that's affected by CYP3A4 or CYP2B6 enzymes counts as one interaction, and there are many in common use. That's why checking your exact prescriptions is so important.
