HelloPharmacist Scorecard of Astaxanthins 10 mg by Signature Supplements

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 one active ingredient: astaxanthin 10 mg per capsule. Astaxanthin is a carotenoid — a type of pigment found naturally in seafood and algae that gives them their reddish color.

It's included in this product as a standalone supplement. The capsule also contains two inactive ingredients: cellulose and diatomaceous earth, which help form and fill out the capsule.

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: Powerful antioxidant.
  • We looked for evidence on: Aging skin, Age-related macular degeneration (AMD), Dry eye, Exercise-induced muscle damage, Exercise-induced muscle soreness, Heart failure — and 4 related terms.
  • The closest evidence on file: Astaxanthin is rated "Insufficient Reliable Evidence To Rate" for Age-related macular degeneration (AMD) (Natural Medicines).
  • Also on file: Astaxanthin is rated "Insufficient Reliable Evidence To Rate" for Aging skin, Heart failure, Dry eye, Exercise-induced muscle soreness, and more.

The evidence for astaxanthin isn't well established yet. Our data shows insufficient reliable evidence to rate it for age-related cognitive decline, age-related macular degeneration (AMD), aging skin, Alzheimer disease, athletic performance, or carpal tunnel syndrome.

That doesn't mean it doesn't work — it means we don't have solid human research showing that it does. If you're considering astaxanthin for one of these conditions, talk with your doctor or pharmacist about whether the current research supports trying it.

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 are abdominal pain, diarrhea, and red-colored stool — the red color is just the pigment coming through.

At the 10 mg dose in this product, side effects are uncommon, but at much higher doses (40 mg daily) severe stomach pain has been reported in a small number of cases. There isn't enough safety data to know whether astaxanthin is safe during pregnancy or breastfeeding.

The safety data advises against use in both situations. If you're pregnant, planning to become pregnant, or breastfeeding, talk with your doctor or pharmacist before starting this supplement.

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 astaxanthin, check any medications you take that are broken down by the CYP3A4 liver enzyme (Moderate severity) — this includes many statins, blood pressure drugs, antihistamines, and others. Also check drugs metabolized by CYP2B6 (Moderate severity), which is a smaller group but still important.

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 may be worth considering if you're interested in antioxidant support and you've checked with your pharmacist about liver-enzyme interactions. If you take any medications metabolized by CYP3A4 or CYP2B6 — a very common group — verify them first.

Skip this product during pregnancy or breastfeeding. Your pharmacist can help you weigh the limited evidence and check your specific drugs.

Astaxanthins 10 mg by Signature Supplements: Common Questions

Does Astaxanthins 10 mg by Signature Supplements interact with any medications?
Yes. Based on its ingredients, Astaxanthins 10 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?
Astaxanthins 10 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 is astaxanthin and why is it in this supplement?
Astaxanthin is a natural pigment found in seafood and algae that acts as an antioxidant in your body. It's included in supplements because people are interested in its potential effects on aging and eye health, though the evidence for these uses is still limited.
Can I take this if I'm pregnant or breastfeeding?
No, there isn't enough safety data on astaxanthin during pregnancy or breastfeeding, so the data advises against use in both situations. Talk with your doctor or pharmacist before taking it if you're pregnant, planning to become pregnant, or nursing.
What side effects should I watch for?
The most common are abdominal pain, diarrhea, and red-colored stool — the red color is just the supplement's pigment and isn't harmful. Severe stomach pain has been reported only at much higher doses than this one. If you notice side effects, stop and contact your pharmacist.
Does astaxanthin actually work for aging skin or eye health?
The evidence isn't well established yet in our data. We don't have enough reliable human research to say whether it works for aging skin, age-related macular degeneration, or other conditions listed. That's why we rate those uses as having insufficient evidence.
Why do I need to check my medications before taking this?
Astaxanthin may speed up how your liver breaks down certain drugs, potentially lowering their levels and making them less effective. Many common medications depend on the CYP3A4 liver enzyme, so it's important to run your exact drugs through the checker on this page.
