HelloPharmacist Scorecard of Astaxanthin 12 mg by Sports Research

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

This product contains one active ingredient: Icelandic Astalif (astaxanthin), a carotenoid — a type of plant pigment with antioxidant properties. You're getting 12 mg per softgel capsule.

The capsule also contains several inactive ingredients: virgin coconut oil, gelatin, glycerin, purified water, and tocopherols (vitamin E), which serve as the capsule shell and preservative.

Does it work?

Couldn't assess
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 assessable

This is a single-ingredient Astaxanthin product and its label doesn't state a use — see Astaxanthin's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence supporting astaxanthin for the conditions listed — age-related cognitive decline, macular degeneration, aging skin, Alzheimer disease, athletic performance, and carpal tunnel syndrome — is insufficient to rate. That means we don't have reliable data yet to say whether it works for any of these uses.

If you're considering this supplement for a specific reason, talk with your pharmacist or doctor about what the current science shows for your particular interest.

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 reported are mild: abdominal pain, diarrhea, and red-colored stools (the red color is from the supplement itself, not bleeding).

Higher doses have occasionally caused more severe stomach pain in a small number of people. There isn't enough safety data to know whether astaxanthin is safe during pregnancy or breastfeeding, so the guidance is to avoid it during both.

If you're pregnant, planning pregnancy, or breastfeeding, talk with your doctor or pharmacist before taking it.

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.

Check your medications against our database if you take drugs metabolized by the liver enzymes CYP3A4 or CYP2B6. These Moderate interactions are theoretical but worth confirming with your exact prescriptions.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Astaxanthin might be worth considering if you're interested in antioxidant support, though evidence for specific health claims is still developing. If you take any prescription medications, especially those for heart rhythm, cholesterol, immune function, or mood, check them against the interaction tool before starting.

Pregnant or breastfeeding? Skip this one unless your doctor says otherwise.

Astaxanthin 12 mg by Sports Research: Common Questions

Does Astaxanthin 12 mg by Sports Research interact with any medications?
Yes. Based on its ingredients, Astaxanthin 12 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 12 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.
Can I take this while pregnant or breastfeeding?
No — there isn't enough safety data to know whether astaxanthin is safe during pregnancy or breastfeeding, so it's best to avoid it. Talk with your doctor or pharmacist about whether it's okay for your situation.
What are the most common side effects?
Mild effects include abdominal pain, diarrhea, and red-colored stools. The red color comes from the supplement itself, not from bleeding. A small number of people taking higher doses have reported more severe stomach pain.
Does this work for anti-aging skin or brain health?
The evidence for astaxanthin in aging skin, cognitive decline, Alzheimer disease, or other claimed uses is insufficient to rate — we don't have reliable data yet saying it works for these purposes. You may want to ask your doctor whether it makes sense for your goals.
Is this the same as the astaxanthin in other supplements?
This product uses Icelandic Astalif as its source of astaxanthin. Different brands use different sources, but the active ingredient is the same. If you're comparing products, the dose (12 mg here) matters most.
What does 'red fecal color' mean?
It means your stool turns red — this is a harmless color change caused by the astaxanthin pigment passing through your digestive system. It's not blood; it's just the supplement's natural color showing up.
