HelloPharmacist Scorecard of Astaxanthin 12 mg by Nutricost

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.

Nutricost Astaxanthin 12 mg is a single-ingredient softgel containing 12 mg of natural astaxanthin per capsule. Astaxanthin is a carotenoid pigment (a type of plant compound) with antioxidant properties.

The softgel also contains inactive ingredients—sunflower oil, gelatin, glycerin, and purified water—to 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 on astaxanthin doesn't support a confident claim for any of the uses it's marketed for. Age-related cognitive decline, age-related macular degeneration (AMD), aging skin, Alzheimer disease, athletic performance, and carpal tunnel syndrome all show insufficient reliable evidence to rate.

That means the research either isn't there yet or isn't strong enough to say whether astaxanthin actually helps with these conditions.

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 orally are abdominal pain, diarrhea, and red-colored stool.

A small number of trial participants on lower doses experienced increased bowel movements and red stool color; at much higher doses (40 mg daily), severe stomach pain has been reported in isolated cases. There isn't enough safety data to recommend astaxanthin during pregnancy or while breastfeeding.

If you're pregnant, planning pregnancy, 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 taking this supplement, check with your doctor or pharmacist if you take any drugs metabolized through your liver's CYP3A4 enzyme system (Moderate severity concern) or CYP2B6 enzyme system (Moderate severity concern). Astaxanthin may theoretically lower the levels of these medications based on lab findings, though this hasn't been confirmed in humans.

Your pharmacist can tell you whether any of your current medications fall into these categories.

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.

Nutricost Astaxanthin 12 mg is a straightforward single-ingredient supplement that's generally well tolerated, though long-term safety data are limited and its effectiveness for the conditions it's promoted for isn't established in our data. The main caution is potential interactions with medications your liver processes through the CYP3A4 and CYP2B6 enzyme systems—these are theoretical based on lab work, not yet proven in humans, but worth discussing with your doctor or pharmacist if you take any prescriptions.

Check your medications and talk it over with your own healthcare provider before you start.

Astaxanthin 12 mg by Nutricost: Common Questions

Does Astaxanthin 12 mg by Nutricost interact with any medications?
Yes. Based on its ingredients, Astaxanthin 12 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 12 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.
Is this safe to take while I'm pregnant or breastfeeding?
There isn't enough safety data on astaxanthin in pregnancy or while breastfeeding. It's best to avoid it during these times. Talk with your doctor or pharmacist about whether it's right for you before you start.
What are the side effects I should watch for?
Astaxanthin is generally well tolerated. The most common side effects are abdominal pain, diarrhea, and red-colored stool. Most people don't experience these, but let your doctor or pharmacist know if you do.
Does astaxanthin actually work for anti-aging or brain health?
The evidence we hold isn't strong enough to say astaxanthin works for age-related cognitive decline, macular degeneration, aging skin, Alzheimer disease, athletic performance, or carpal tunnel syndrome. More research is needed.
Why is it important to tell my doctor about this supplement if I take medications?
Lab studies suggest astaxanthin may theoretically slow how your body clears certain prescription drugs, which could lower their effectiveness. This hasn't been proven in humans yet, but it's worth checking your specific medications with your doctor or pharmacist beforehand.
What's actually in this supplement besides astaxanthin?
The softgel contains sunflower oil, gelatin, glycerin, and purified water—these are inactive ingredients that deliver the astaxanthin. There are no added fillers or binders beyond what's needed for the capsule itself.
