HelloPharmacist Scorecard of Omega-3 Fish + Krill Oil 1000 mg by Bronson

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 4 of its 4 active ingredients.
  • “Total Omega-3 Fatty Acids” is listed as a grouped ingredient — the label gives one combined amount (680 mg) without saying how much of each component you get.
  • “Proprietary Blend of Fish and Krill Oil” is a proprietary blend — the label gives one combined amount (1,000 mg) without saying how much of each component you get.

This softgel delivers 1,000 mg of total omega-3 fatty acids from fish and krill oil, including eicosapentaenoic acid and docosahexaenoic acid — the two marine omega-3s most studied for heart and brain health. It also contains astaxanthin, a red pigment from krill with antioxidant properties.

The capsule itself is made from gelatin, glycerin, purified water, and ethyl vanillin.

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: heart, joint, brain, and eye health.
  • We looked for evidence on: Age-related cognitive decline, Age-related macular degeneration (AMD), Alzheimer disease, Dry eye, Heart failure, Hyperlipidemia — 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.

The product facts we hold don't include effectiveness ratings for general omega-3 support or the conditions fish oil is commonly used for. Astaxanthin has insufficient reliable evidence to rate it for age-related cognitive decline, macular degeneration, aging skin, Alzheimer disease, athletic performance, or carpal tunnel syndrome.

If you're considering this for a specific health goal, talk it over with your doctor or pharmacist to see what the broader research says.

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, though long-term safety data are limited. The most common side effects are abdominal pain, diarrhea, and red-colored stools — a harmless cosmetic effect.

At lower doses (6 mg daily), increased bowel movements and red stools appeared in a small number of trial participants; at much higher doses (40 mg daily), severe stomach pain occurred in two patients. Astaxanthin is not recommended in pregnancy or while breastfeeding because there isn't enough safety data.

We could not check pregnancy and breastfeeding safety for the omega-3 ingredients themselves.

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 taking this product, check with your doctor or pharmacist if you take any medications metabolized by CYP3A4 or CYP2B6 enzymes — these are Moderate-severity interactions where astaxanthin may lower your drug levels. This includes a very large number of prescription medications, so it's worth verifying your specific drugs using the checker on this page.

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 product is a straightforward omega-3 supplement from fish and krill with an added antioxidant. If you take medications metabolized by CYP3A4 or CYP2B6 — a very common group that includes many heart, blood pressure, cholesterol, and immune drugs — check with your doctor or pharmacist before starting it.

If you're pregnant, breastfeeding, or have a history of gastrointestinal sensitivity, talk it over with your healthcare provider first.

Omega-3 Fish + Krill Oil 1000 mg by Bronson: Common Questions

Does Omega-3 Fish + Krill Oil 1000 mg by Bronson interact with any medications?
Yes. Based on its ingredients, Omega-3 Fish + Krill Oil 1000 mg has a known interaction with 671 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Omega-3 Fish + Krill Oil 1000 mg 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 are the side effects of this product?
Abdominal pain, diarrhea, and red-colored stools are the main ones reported. Red stools are just a harmless color change from the astaxanthin. In trial doses of 6 mg astaxanthin daily, a few people had increased bowel movements; at much higher doses (40 mg), two patients experienced severe stomach pain. Most people tolerate it well.
Can I take this if I'm pregnant or breastfeeding?
Astaxanthin isn't recommended in pregnancy or while breastfeeding because there isn't enough safety data. We don't have safety information on file for the omega-3 ingredients either. Talk with your doctor or pharmacist about whether this product is right for you in those situations.
Does this product actually work for heart health or brain health?
The product facts we hold don't include effectiveness data for general omega-3 support or common uses like heart or brain health. For details on what research says about fish oil omega-3s for your particular reason for considering it, ask your doctor or pharmacist.
What's astaxanthin and why is it in here?
Astaxanthin is a red pigment that comes from krill and has antioxidant properties. It's added to this formula as a supporting ingredient, though we don't have reliable evidence that it helps with specific conditions like aging skin or cognitive decline.
Will this interfere with my blood pressure or heart medication?
Possibly — astaxanthin may lower the blood levels of many drugs in those categories if they're metabolized by your liver's CYP3A4 or CYP2B6 enzymes. Check the medication search tool on this page with your exact drug names, or ask your pharmacist or doctor before starting.
