HelloPharmacist Scorecard of Astaxanthin 12 mg by Dr. Mercola

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 has one active ingredient: astaxanthin, a natural red pigment found in certain algae and seafood. It's an antioxidant—a compound that may help protect cells from damage.

The rest of what's in the capsule is olive oil, fish gelatin, mixed tocopherols (a form of vitamin E), and rosemary leaf extract, which serve as carriers or preservatives.

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.

We hold insufficient evidence to rate astaxanthin for the conditions listed in the data—age-related cognitive decline, age-related macular degeneration, aging skin, Alzheimer disease, athletic performance, and carpal tunnel syndrome. That doesn't mean it doesn't work; it means the research we have isn't solid enough yet to make a clear call.

If you're considering this for a specific condition, your doctor or pharmacist can point you toward the latest research.

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 the studies we have, but long-term safety data are limited—we simply don't know what happens with years of use. The most common side effects are stomach pain, diarrhea, and red-colored stools.

Higher doses (40 mg daily) have caused severe stomach pain in a small number of people. During pregnancy and breastfeeding, there isn't enough safety data, so it's best to avoid astaxanthin unless you talk with your doctor or pharmacist first.

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 product, check with your pharmacist if you take any drugs that use the CYP3A4 or CYP2B6 pathways in your liver—astaxanthin may reduce how well they work. Many common medications use these pathways, so it's worth a quick conversation.

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 is an antioxidant supplement with limited long-term safety data and unproven effectiveness for most advertised uses. If you take medications processed by your liver, check them against the interaction tool below before starting.
