HelloPharmacist Scorecard of Astaxanthin 4 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.

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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains a single active ingredient: astaxanthin 4 mg per softgel. Astaxanthin is a red carotenoid — a pigment found in certain seafood and algae — that acts as an antioxidant in the body.

The softgel itself is made with safflower oil, gelatin, glycerine, purified water, yellow beeswax, and lecithin as inactive ingredients.

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: Healthy immune and cardiovascular systems.
  • We looked for evidence on: Heart failure, Hyperlipidemia, Hypertension, Metabolic syndrome, Stroke, Coronary artery disease — 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, Metabolic syndrome.

The evidence for astaxanthin isn't established enough yet to rate it. We hold insufficient reliable evidence for age-related cognitive decline, age-related macular degeneration, aging skin, Alzheimer disease, athletic performance, and carpal tunnel syndrome — all conditions people sometimes ask about.

That doesn't mean it doesn't work; it means the studies we have aren't strong enough to say either way.

The evidence, ingredient by ingredient 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, though long-term safety data are limited. The most common side effects from oral use are abdominal pain, diarrhea, and red-colored stool — the last is usually harmless and tied to the pigment itself.

At the dose in this product (4 mg), serious side effects are unlikely, though higher doses (40 mg) have caused severe abdominal pain in rare cases. Pregnancy and breastfeeding: There isn't enough safety data, so it's best to avoid astaxanthin during pregnancy and while breastfeeding.

Talk with your doctor or pharmacist about your specific situation.

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 whether you take any medications metabolized by CYP3A4 or CYP2B6 enzymes — a large group that includes many blood pressure medications, statins, immunosuppressants, and other drugs. Astaxanthin may theoretically reduce their levels.

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.

Astaxanthin 4 mg is a single-ingredient antioxidant supplement generally well tolerated at this dose. The main thing to watch is potential interactions with medications your liver breaks down — especially blood pressure drugs and statins.

Astaxanthin 4 mg by Bronson: Common Questions

Does Astaxanthin 4 mg by Bronson interact with any medications?
Yes. Based on its ingredients, Astaxanthin 4 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?
Astaxanthin 4 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.
Does astaxanthin actually work for anti-aging or brain health?
The evidence isn't strong enough yet to say. We have insufficient reliable data on astaxanthin for age-related cognitive decline, macular degeneration, aging skin, Alzheimer disease, athletic performance, and carpal tunnel syndrome. More research is needed.
What are the side effects?
At 4 mg, astaxanthin is generally well tolerated. The most common side effects are abdominal pain, diarrhea, and red-colored stool — the last is usually just the pigment passing through. Long-term safety data are limited, though.
Is it safe during pregnancy or while breastfeeding?
There isn't enough safety data, so it's best to avoid astaxanthin during pregnancy and while breastfeeding. Talk with your doctor or pharmacist about whether it's right for you in these situations.
What exactly is astaxanthin?
It's a red pigment called a carotenoid, found naturally in seafood and algae. It works as an antioxidant in your body — meaning it helps protect cells from oxidative damage.
Can I take this with my blood pressure or cholesterol medication?
That depends on which drug you take. Astaxanthin may theoretically reduce levels of medications broken down by your liver. Use the medication checker on this page with your exact prescription names to see if there's a concern.
