HelloPharmacist Scorecard of Astaxanthin 6 mg by Terry Naturally

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 product contains one active ingredient: natural astaxanthin at 6 mg per softgel. Astaxanthin is a carotenoid — a naturally occurring pigment — often studied for its antioxidant properties.

The capsule also contains several inactive ingredients (extra virgin olive oil, gelatin, glycerin, and purified water) that serve as the carrier and capsule material.

Does it work?

Insufficient evidence
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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: heart, blood vessel, and immune health.
  • We looked for evidence on: Heart failure, Hypertension, Hyperlipidemia, Stroke, Exercise-induced muscle damage, Exercise-induced muscle soreness — and 3 related terms.
  • The closest evidence on file: Astaxanthin is rated "Insufficient Reliable Evidence To Rate" for Heart failure (Natural Medicines).
  • Also on file: Astaxanthin is rated "Insufficient Reliable Evidence To Rate" for Exercise-induced muscle soreness, Hyperlipidemia, Hypertension, Stroke, and more.

The evidence we have on 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. In plain terms, we don't yet have reliable data showing this dose works for any of these uses.

If you're considering astaxanthin for a specific health concern, talk it over with your doctor or pharmacist to see what the current research suggests for your situation.

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 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 stool — a harmless discoloration caused by the pigment itself.

At the 6 mg dose studied, a small number of participants experienced increased bowel movements and red stool; higher doses (40 mg daily) have caused severe stomach pain in a few cases. Because there isn't enough safety data, astaxanthin is best avoided during pregnancy and while breastfeeding.

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

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 taking this product, check with your doctor or pharmacist if you take any medications broken down by the liver enzymes CYP3A4 or CYP2B6. These include (but are not limited to) certain statins, heart medications, immunosuppressants, and cancer drugs.

Astaxanthin may theoretically lower their levels and reduce effectiveness, though this hasn't been confirmed in people yet.

The bottom line

Scorecard at a glanceFully disclosed formula with insufficient evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Astaxanthin 6 mg may be worth considering if you're looking for an antioxidant supplement, and it's generally well tolerated at this dose. However, because of its potential to affect how your liver processes certain medications, it's important to check your exact drug list before starting — especially if you take heart medications, immunosuppressants, or drugs that require stable blood levels.

Talk with your doctor or pharmacist to make sure it's a good fit for you alongside your current regimen.

Astaxanthin 6 mg by Terry Naturally: Common Questions

Does Astaxanthin 6 mg by Terry Naturally 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 does astaxanthin do?
Astaxanthin is a carotenoid — a natural pigment with antioxidant properties — that's being studied for several age-related health concerns. However, we don't have reliable evidence yet that it works for conditions like cognitive decline, macular degeneration, or aging skin at this dose.
Will this supplement give me red stool?
It's possible. A small number of people taking this dose reported red-colored stool, which is just the pigment in astaxanthin passing through. It's harmless but can be unsettling if you're not expecting it.
Can I take this while pregnant or breastfeeding?
There isn't enough safety data to know. It's best to avoid astaxanthin during pregnancy and while breastfeeding. Talk with your doctor or pharmacist about whether it's right for you.
How long does it take to work?
We don't have reliable data on how effective astaxanthin is for any of the conditions it's marketed for, so we can't tell you when or if you'd notice a benefit. If you're curious about a specific use, ask your doctor what the research shows.
Will this affect my other medications?
Astaxanthin may theoretically lower blood levels of drugs broken down by two liver enzymes (CYP3A4 and CYP2B6), which covers a lot of medications. You'll want to check your exact drug list with the tool on this page or with your pharmacist before starting.
