HelloPharmacist Scorecard of Organic Astaxanthin by Purity Labs

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

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 (AstaPure), a red pigment found in algae and seafood. Astaxanthin is an antioxidant — a compound that may help protect your cells from damage.

The tablet or pill also contains inactive ingredients (FirmBond and Nutrapure) that help hold the pill together and deliver the astaxanthin.

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 doesn't establish that astaxanthin works for any of the uses it's marketed for — age-related cognitive decline, macular degeneration, aging skin, Alzheimer disease, athletic performance, or carpal tunnel syndrome all carry insufficient evidence ratings in our data. That doesn't mean it doesn't work; it means the research we have access to isn't strong enough to say one way or the other.

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 stools — the red color is from the astaxanthin itself, not a sign of bleeding.

A small number of people in trials experienced increased bowel movements at lower doses, and two patients on a much higher dose reported severe stomach pain. There isn't enough safety data to know whether astaxanthin is safe in pregnancy or while breastfeeding.

If you're pregnant, planning pregnancy, or nursing, talk with your doctor or pharmacist about whether to use this product — the safety data advises against it.

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 you take this product, check whether you're on any medications metabolized by your liver's CYP3A4 or CYP2B6 enzymes — astaxanthin may speed up how quickly your body breaks them down and reduce their effectiveness. Use the medication checker on this page to verify 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.

If you're curious about astaxanthin for an age-related or skin concern, it's generally well tolerated, but don't expect strong evidence that it'll work. The bigger question is your medications — run them through our checker first.

And if you're pregnant or breastfeeding, check with your pharmacist before starting.

Organic Astaxanthin by Purity Labs: Common Questions

Does Organic Astaxanthin by Purity Labs interact with any medications?
Yes. Based on its ingredients, Organic Astaxanthin 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?
Organic Astaxanthin 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 what's it supposed to do?
Astaxanthin is a red antioxidant compound found naturally in algae and seafood. It's marketed for age-related cognitive decline, eye health, skin aging, and athletic performance — but we don't have strong evidence that it works for any of those uses yet.
What are the most common side effects?
Abdominal pain, diarrhea, and red-colored stools are the main ones reported in studies. The red stools are just from the astaxanthin's color, not a medical problem. Most people tolerate it well.
Can I take this if I'm pregnant or breastfeeding?
There isn't enough safety data to know. The data available advises against it during pregnancy and while breastfeeding — talk with your doctor or pharmacist to decide what's best for your situation.
How do I know if this will interact with my medications?
Astaxanthin can theoretically affect how your liver breaks down many medications. Use the medication checker on this page to search your specific prescriptions — that's the most reliable way to know if there's a concern.
Is astaxanthin safe long-term?
It's generally well tolerated in short-term studies, but we don't have much data on what happens if you take it for years. If you're planning to use it long-term, check in with your pharmacist.
