HelloPharmacist Scorecard of Astaxanthin 20 mg by AOR Advanced Orthomolecular Research Premium

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.

This softgel delivers a single active ingredient: astaxanthin 20 mg, a carotenoid pigment derived from algae. It's wrapped in safflower oil, tocopherols (vitamin E), and a softgel capsule to help your body absorb it.

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

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Supports healthy cells.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

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

That doesn't mean it doesn't work — it means the research to prove it either isn't there yet or isn't strong enough to be certain. Talk with your doctor or pharmacist about whether it makes sense for what you're looking to support.

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 are abdominal pain, diarrhea, and red-colored stools — the red color is normal and comes from the pigment itself.

A small number of trial participants at higher doses experienced increased bowel movements or severe stomach pain. There isn't enough safety data to recommend astaxanthin during pregnancy or while breastfeeding.

Talk with your doctor or pharmacist before taking it if you're pregnant, planning to become pregnant, or nursing.

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, check with your doctor or pharmacist if you take any medications broken down by the liver enzymes CYP3A4 or CYP2B6 — astaxanthin may reduce their blood levels. This includes many common drugs like certain statins, blood pressure medicines, and immunosuppressants.

The interaction is theoretical (shown in lab cells, not yet proven in people), but it's worth confirming your medications are safe to combine with this product.

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 a single-ingredient antioxidant supplement that's generally well tolerated but lacks strong evidence of benefit for the conditions it's marketed for. If you take medications metabolized by your liver, check your specific drugs before starting — the product may lower their levels.

Your doctor or pharmacist can help you decide whether it's worth trying and whether it's safe with your current regimen.

Astaxanthin 20 mg by AOR Advanced Orthomolecular Research Premium: Common Questions

Does Astaxanthin 20 mg by AOR Advanced Orthomolecular Research Premium interact with any medications?
Yes. Based on its ingredients, Astaxanthin 20 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 20 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.
What exactly is astaxanthin?
Astaxanthin is a carotenoid — a natural pigment from algae that acts as an antioxidant in your body. It's the red color you see in salmon and shrimp.
Will this help with my aging skin or memory?
We don't have reliable evidence it works for either. The research to prove benefit for aging skin, cognitive decline, or Alzheimer disease isn't strong enough to say. Your doctor can discuss whether a trial might be worth it for you.
Is it safe to take while pregnant or nursing?
There isn't enough safety data. It's best to avoid it during pregnancy and breastfeeding. Talk with your doctor or pharmacist if you're in either situation and considering it.
What side effects might I notice?
Most people tolerate it well. Some may experience belly pain, diarrhea, or red-colored stools (the red is from the pigment and is harmless). Higher doses have rarely caused severe stomach pain.
Why does the product have safflower oil and tocopherols if astaxanthin is the only active ingredient?
Safflower oil and tocopherols (vitamin E) are inactive ingredients that help your body absorb the astaxanthin and keep the softgel stable. They're not active treatments — just part of how the supplement is formulated.
