HelloPharmacist Scorecard of Astaxanthin 5 mg by Puritan's Pride

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 16, 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 supplement contains one active ingredient: astaxanthin, a carotenoid (a type of plant pigment with antioxidant properties) at 5 mg per softgel. The inactive ingredients are sunflower seed oil, gelatin, and glycerin, which make up the softgel capsule itself.

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 for astaxanthin is not established in the data we hold. Studies have looked at it for age-related cognitive decline, macular degeneration (a cause of vision loss in aging), aging skin, Alzheimer disease, athletic performance, and carpal tunnel syndrome — but the current evidence is insufficient to rate whether it actually works for any of these.

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 abdominal pain, diarrhea, and red fecal color (a harmless discoloration of stool).

Higher doses have been associated with 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 while breastfeeding.

If you're pregnant, planning to become pregnant, or nursing, talk with your doctor or pharmacist before taking this supplement.

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 supplement, double-check any drugs your liver breaks down, especially those metabolized by the CYP3A4 or CYP2B6 enzymes. This includes many heart, blood pressure, cholesterol, transplant rejection, psychiatric, and anti-seizure medications.

The interaction is rated Moderate, meaning astaxanthin may lower their blood levels. Talk it over with your doctor or pharmacist and use the medication checker on this page 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 is an antioxidant that some people take for aging-related concerns, but we don't yet have solid evidence it works for any specific condition. If you're on prescription medications — especially those processed by your liver — you'll want to check with your doctor or pharmacist before starting it, since it may affect how well certain drugs work.

Generally well tolerated, but long-term safety data are thin.
