HelloPharmacist Scorecard of Astaxanthin 12 mg by Nature's Lab

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

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: AstaReal Astaxanthin, a naturally derived carotenoid (a pigment compound) at 12 mg per softgel. Astaxanthin is the bright red compound found in algae and seafood that gives salmon and shrimp their color.

The softgel itself is made from gelatin, extra virgin olive oil, glycerin, purified water, and mixed tocopherols (a form of vitamin E), which help preserve the astaxanthin.

Does it work?

No specific claim
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
General wellness

This Astaxanthin product is marketed for general wellness, not a specific health condition, so there's no single claim to grade — see Astaxanthin's own graded uses on its monograph.

Why this rating?
  • The label markets general wellness (“antioxidant support”), not a specific health condition, so there is no single claim to grade against clinical-evidence data.

The evidence for astaxanthin isn't established in our data. We hold insufficient reliable evidence to rate it for age-related cognitive decline, age-related macular degeneration (AMD), aging skin, Alzheimer disease, athletic performance, or carpal tunnel syndrome.

While astaxanthin is sold for these uses, we don't have the clinical trial data to back them up. Talk with your doctor about whether it might be worth trying for your specific concern.

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 are abdominal pain, diarrhea, and red-colored stools (the red color comes from the astaxanthin itself and isn't dangerous).

At the 12 mg dose in this product, side effects are uncommon, though higher doses (around 40 mg daily) have caused severe stomach pain in a few people. There isn't enough safety data to know whether astaxanthin is safe in pregnancy or while breastfeeding, so the evidence-based recommendation is to avoid it during these times.

Talk with your doctor or pharmacist for personalized advice about your situation.

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.

Check your medications before starting astaxanthin if you take drugs metabolized by CYP3A4 or CYP2B6 enzymes. This includes many statins, some blood pressure medications, immunosuppressants, and other commonly prescribed drugs — astaxanthin may lower their blood levels and reduce how well they work.

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

The bottom line

Scorecard at a glanceFully disclosed formula marketed for general wellness rather than one specific gradeable purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Astaxanthin 12 mg might appeal to you if you're interested in a carotenoid supplement and you're not pregnant or breastfeeding. The main thing to watch is whether you take medications broken down by your liver — especially common blood pressure and cholesterol drugs.

Before you start, run your exact medications through the checker on this page, then confirm with your own doctor or pharmacist that it's okay to combine them.

Formula

Astaxanthin is a naturally occurring carotenoid that, due to its unique structure, performs an important role in cellular free radical protection. Astaxanthin is one of nature's most powerful antioxidants. Wild salmon, krill and shrimp derive their pink color from a diet rich in microalgae - a critical source of astaxanthin. Nature's Lab uses AstaReal Astaxanthin, one of the most studied brands as astaxanthin in the world. It is non-GMO, haematococcus pluvial micro algae and is farmed in the U.S.A. to ensure both quality and stability.

Astaxanthin 12 mg by Nature's Lab: Common Questions

Does Astaxanthin 12 mg by Nature's Lab 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.
Can I take this if I'm pregnant or breastfeeding?
There isn't enough safety data to know either way. The evidence-based recommendation is to avoid astaxanthin during pregnancy and breastfeeding. Talk with your doctor or pharmacist about your specific situation — they can help you decide whether the benefit might outweigh the unknown risk.
What does astaxanthin actually do?
Astaxanthin is a natural red pigment from algae and seafood that acts as an antioxidant in your body. It's marketed for things like brain health, eye health, and skin aging, but we don't have reliable clinical trial evidence to confirm it works for any of those uses in the data we hold.
Will my stool really turn red?
Yes, red-colored stools are common with astaxanthin and completely harmless — it's just the color of the supplement coming through. If you also see abdominal pain or diarrhea, those are the side effects to watch for, though they're uncommon at this dose.
Is astaxanthin safe to take long-term?
Studies show it's generally well tolerated, but we don't have a lot of long-term safety data. If you plan to take it for months or years, that's worth discussing with your doctor, especially if you're on medications that might be affected by the liver enzyme interaction.
What if I'm on a cholesterol or blood pressure medication?
Many of those drugs are metabolized by the liver enzymes that astaxanthin may speed up, which could lower your medication levels. Check your exact medications with the interaction tool on this page, then talk with your doctor or pharmacist before you start.
