HelloPharmacist Scorecard of Astaxanthin 6 mg by NutriCology

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.

Astaxanthin 6 mg by NutriCology contains one active ingredient: astaxanthin, a naturally occurring carotenoid (a type of pigment found in algae and seafood). The inactive ingredients are gelatin, water, extra virgin olive oil, glycerin, and D-alpha-tocopherol (a form of vitamin E), which are used as the capsule shell and to help your body absorb the astaxanthin.

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: benefit brain, eyes, muscles, skin, heart, and organs.
  • We looked for evidence on: Age-related cognitive decline, Age-related macular degeneration (AMD), Aging skin, Alzheimer disease, Athletic performance, Diabetes — and 4 related terms.
  • The closest evidence on file: Astaxanthin is rated "Insufficient Reliable Evidence To Rate" for Age-related cognitive decline (Natural Medicines).
  • Also on file: Astaxanthin is rated "Insufficient Reliable Evidence To Rate" for Age-related macular degeneration (AMD), Aging skin, Alzheimer disease, Athletic performance, and more.

The evidence for astaxanthin's effectiveness isn't established in the data we hold. The supplement is marketed for age-related cognitive decline, macular degeneration (age-related eye disease), aging skin, Alzheimer disease, athletic performance, and carpal tunnel syndrome — but for all these uses, the reliable evidence to rate it is insufficient.

That doesn't mean it doesn't work; it means the research so far hasn't met the bar to confirm it does.

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, though long-term safety data are limited. The most common side effects are abdominal pain, diarrhea, and red-colored stools — the latter being harmless and simply a sign the supplement is passing through your system.

At the 6 mg dose in this product, a small number of study participants reported increased bowel movements and red fecal color. There isn't enough safety data to know either way whether astaxanthin is safe during pregnancy or while breastfeeding.

Talk with your doctor or pharmacist for personalized advice if you're pregnant, planning to become pregnant, or nursing.

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 pharmacist or doctor if you take any medications metabolized by CYP3A4 or CYP2B6 enzymes. Astaxanthin may theoretically speed up how your liver clears these drugs, potentially making them less effective — though this hasn't been proven in people yet.

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 supporting eye health or cognition as you age, though the evidence isn't yet solid. The main thing to do before starting is check whether you take any medications metabolized by CYP3A4 or CYP2B6 enzymes — use the tool on this page or talk to your pharmacist to confirm your prescriptions won't be affected.

If you're pregnant or breastfeeding, or taking any medications, check with your doctor or pharmacist first.

Astaxanthin 6 mg by NutriCology: Common Questions

Does Astaxanthin 6 mg by NutriCology 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 is astaxanthin and where does it come from?
Astaxanthin is a pigment (carotenoid) that occurs naturally in algae and seafood. In this product, it's supplied as a 6 mg softgel to make it easy to take.
Can I take this if I'm pregnant or breastfeeding?
There isn't enough safety data to know either way. The facts we hold advise caution, so it's best to talk with your doctor or pharmacist before taking it during pregnancy or while nursing.
What side effects might I experience?
Most people tolerate it well. The most common effects are abdominal pain, diarrhea, and red-colored stools — the last one is harmless and just means the supplement is passing through. A small number of people at this dose reported increased bowel movements.
Does astaxanthin actually work for age-related eye disease or memory?
That's not yet established in the data we hold. It's marketed for those purposes, but the reliable evidence to confirm it works is insufficient so far.
Why do I need to check my medications before taking this?
Astaxanthin may speed up how your liver breaks down certain drugs, potentially making them less effective. Lab research shows it affects two major liver enzymes, though this hasn't been proven in people yet. Your pharmacist can help you check whether your prescriptions are affected.
