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 — a naturally occurring plant pigment — that your body doesn't produce on its own.

The softgel also contains inactive ingredients for the capsule and base: safflower oil, gelatin, MCT oil, sorbitol sorbitan solution, water, and D-alpha-tocopherol (a form of vitamin E).

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 doesn't support a reliable rating for astaxanthin in any of its studied uses, including age-related cognitive decline, macular degeneration of the eye (a form of vision loss), aging skin, Alzheimer disease, athletic performance, or carpal tunnel syndrome. For each of these, the data is marked insufficient to determine whether it works.

If you're considering this supplement for one of these reasons, talk it over with your doctor or pharmacist about whether the current evidence is enough to justify a trial.

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 remain limited. The most common side effects reported are mild: abdominal pain, diarrhea, and red-colored stool (a harmless result of the pigment itself).

At the 12 mg dose in this product, side effects are expected to be uncommon. At much higher doses — 40 mg daily — some people have reported severe stomach or abdominal pain, so staying within recommended doses is prudent.

During pregnancy, there isn't enough safety data, so it's best to avoid this supplement. The same applies to breastfeeding — the data to confirm safety doesn't exist.

If you're pregnant, planning pregnancy, or breastfeeding, talk with your doctor or pharmacist before taking it.

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 Nutricost Astaxanthin, double-check with your doctor or pharmacist if you take medications metabolized by CYP3A4 or CYP2B6 enzymes in your liver — these are Moderate severity interactions. This includes many common drugs for heart rhythm, blood pressure, cholesterol, and other conditions.

Astaxanthin may theoretically decrease their levels, though human evidence is still lacking.

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 may be worth considering if you're interested in a natural carotenoid supplement, but the evidence doesn't yet prove it works for any of its marketed uses. The main caution is its potential to speed up how your liver processes certain medications — a theoretical risk based on lab work, not yet confirmed in humans.

Before you start, check your exact medications with your doctor or pharmacist, especially if you take drugs for heart rhythm, blood pressure, cholesterol, or any chronic condition metabolized by your liver.

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 astaxanthin safe to take while pregnant or breastfeeding?
No. There isn't enough safety data for either pregnancy or breastfeeding, so the guidance is to avoid it in both cases. Talk with your doctor or pharmacist for personalized advice if you're pregnant, planning to become pregnant, or breastfeeding.
What side effects might I notice?
Most people tolerate astaxanthin well. The most common side effects are mild — abdominal discomfort, diarrhea, and red-colored stool (which is harmless and just the pigment passing through). Severe stomach pain is rare and was reported only at much higher doses.
Does astaxanthin actually work for anti-aging or brain health?
The evidence we have isn't strong enough to say for sure. Astaxanthin has been studied for age-related cognitive decline, eye health, skin aging, Alzheimer disease, athletic performance, and carpal tunnel syndrome — but in each case, the data is insufficient to prove it works.
Why does this product interact with so many medications?
Astaxanthin appears to speed up one of your liver's main drug-processing pathways (CYP3A4), which clears a large number of common prescription medications. That's why the interaction count is high — not because astaxanthin is unusual, but because that liver pathway handles hundreds of drugs.
What is astaxanthin, exactly?
It's a carotenoid — a naturally occurring pigment found in certain algae and seafood. Your body can't make it on its own, so it can only come from diet or supplements. It's what gives salmon and shrimp their pink color.
