HelloPharmacist Scorecard of Astaxanthin 15 mg by Micro Ingredients

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 15 mg per softgel capsule. Astaxanthin is a carotenoid—a naturally occurring pigment compound found in algae and seafood that your body can use as an antioxidant.

The capsule itself is a vegetarian softgel, an inactive ingredient that holds 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 for astaxanthin's effectiveness is not established in the data we hold. For the conditions it's marketed for—including age-related cognitive decline, macular degeneration of the eye, aging skin, Alzheimer disease, athletic performance, and carpal tunnel syndrome—our monograph shows insufficient reliable evidence to rate it.

That doesn't mean it doesn't work; it means the studies so far aren't strong enough to draw firm conclusions. If you're considering it for a specific reason, talk with your doctor about whether the current evidence supports a try.

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, but long-term safety data are limited, so we don't have a complete picture of how it performs over years. The most common side effects reported orally are abdominal pain, diarrhea, and red-colored stools—the red color is due to astaxanthin itself and isn't harmful.

At the 15 mg dose in this product, such effects are uncommon; they've been more frequent at much higher doses (40 mg daily). During pregnancy, there isn't enough safety data, so it's best to avoid it.

The same applies to breastfeeding—there's insufficient information to know whether it's safe, so talk with your doctor or pharmacist for personalized advice.

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 start astaxanthin, double-check any medications your liver breaks down, especially those processed by CYP3A4 or CYP2B6 enzymes—astaxanthin may lower their levels and reduce how well they work. This includes many heart drugs, immunosuppressants, and others.

Use the interaction checker on this page with your exact medications, then confirm with your own doctor or pharmacist.

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 15 mg may be worth considering if you're interested in antioxidant support, but the evidence for specific health claims is not yet established. If you take any medications metabolized by your liver—which is most drugs—check them against this product's interaction list before starting.

And if you're pregnant, breastfeeding, or taking medications, talk with your doctor or pharmacist first.

Astaxanthin 15 mg by Micro Ingredients: Common Questions

Does Astaxanthin 15 mg by Micro Ingredients interact with any medications?
Yes. Based on its ingredients, Astaxanthin 15 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 15 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.
Can I take this while pregnant or breastfeeding?
There isn't enough safety data to know either way. The facts advise against it during both pregnancy and breastfeeding because we simply don't have the studies. Talk with your doctor or pharmacist before using it in these situations—they can weigh the risks and benefits for your personal health.
What are the side effects?
Astaxanthin is generally well tolerated. The most common side effects reported are abdominal pain, diarrhea, and red-colored stools. The red color comes from astaxanthin itself and isn't dangerous. At the 15 mg dose in this product, these effects are uncommon.
Does this really help with aging skin, eye health, or memory?
The evidence isn't strong enough yet for us to say. Our data shows insufficient reliable evidence to rate astaxanthin for those uses—including age-related cognitive decline, macular degeneration, aging skin, Alzheimer disease, athletic performance, and carpal tunnel syndrome. You may want to talk with your doctor about the current evidence if you're considering it for a specific reason.
What exactly is astaxanthin?
It's a carotenoid—a pigment compound that occurs naturally in algae and seafood. Your body uses it as an antioxidant, which is why people take it as a supplement.
Will this interfere with my medications?
Possibly. In the lab, astaxanthin appears to speed up how your liver breaks down certain drugs—specifically those handled by CYP3A4 and CYP2B6 enzymes. This could lower their levels and make them less effective, but it hasn't been confirmed in actual patients. Use the checker on this page with your exact medications, then confirm with your doctor or pharmacist before starting.
