HelloPharmacist Scorecard of Astaxanthin 6 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: astaxanthin 6 mg from Icelandic Astalif, a natural red pigment derived from algae. It's packaged in a softgel with virgin coconut oil, gelatin, glycerin, purified water, and tocopherols (a form of vitamin E) as inactive ingredients.

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 we hold for astaxanthin doesn't establish its effectiveness for the uses listed — age-related cognitive decline, macular degeneration, aging skin, Alzheimer disease, athletic performance, and carpal tunnel syndrome. Each has been rated insufficient reliable evidence, meaning the current research hasn't been strong enough to draw firm conclusions.

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 at this 6 mg dose is generally well tolerated in studies, though long-term safety data are limited. The most common side effects reported are abdominal pain, diarrhea, and red-colored stools — a harmless color change from the astaxanthin itself.

At this dose, a small number of trial participants experienced increased bowel movements or red stool color. The safety data advises against using astaxanthin during pregnancy and breastfeeding, so if you're pregnant, nursing, or planning to be, talk with your doctor or pharmacist before starting.

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 any medications you take that are metabolized by the liver enzymes CYP3A4 and CYP2B6 — a category that spans hundreds of drugs including many heart, cholesterol, immune, and nervous-system medications. Astaxanthin may theoretically lower their blood levels, though this hasn't been confirmed in patients.

Talk to your pharmacist about your specific 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 may appeal to you if you're interested in a natural antioxidant, but the evidence for specific benefits isn't yet established. The main thing to watch is its potential to lower blood levels of medications your liver breaks down — which includes a lot of common drugs.

Before you start, check your medications with the tool here or ask your pharmacist.

Astaxanthin 6 mg by Sports Research: Common Questions

Does Astaxanthin 6 mg by Sports Research interact with any medications?
Yes. Based on its ingredients, Astaxanthin 6 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 6 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 exactly is astaxanthin?
Astaxanthin is a red pigment that comes from algae — in this case, Icelandic Astalif. It's a type of antioxidant that may help protect cells from oxidative stress, though we don't yet have strong evidence for specific health benefits at this dose.
Is this safe to take while pregnant or breastfeeding?
No, the safety data aren't there. It's best to avoid astaxanthin during pregnancy and while breastfeeding. If you're in either situation and interested in it, talk with your doctor or pharmacist first.
What are the side effects?
Most people tolerate it well. The most common side effects are abdominal pain, diarrhea, and red-colored stools — the red color is just the astaxanthin and isn't harmful. A small number of people in studies had more bowel movements or noticed the red stool color.
Does astaxanthin work for memory or brain health?
The evidence we have isn't strong enough to say. Astaxanthin for age-related cognitive decline and Alzheimer disease are both rated insufficient reliable evidence, meaning more research is needed before we know if it actually helps.
Why does the product say it may interact with so many medications?
Astaxanthin may speed up how your liver breaks down certain drugs, which could lower their blood levels and make them less effective. That's based on lab studies, not yet confirmed in patients — but because so many common medications depend on those same liver pathways, it's worth checking your specific prescriptions.
