HelloPharmacist Scorecard of Astaxanthin 8 mg by ResVitale

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: AstaPure astaxanthin, a naturally derived carotenoid (pigment) in a dose of 8 mg per capsule. The capsule itself and the other ingredients listed are inactive — vegetarian capsule shell, soy protein, corn starch, rice bran, vegetable cellulose, silica, ascorbyl palmitate, and DL-alpha-tocopherol — they're there to hold and protect the astaxanthin.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Astaxanthin's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: support and maintain healthy central nervous system.
  • We looked for evidence on: Age-related cognitive decline, Alzheimer disease, Parkinson disease, neurodegeneration, neuroprotection.
  • The closest evidence on file: Astaxanthin is rated "Insufficient Reliable Evidence To Rate" for Age-related cognitive decline (Natural Medicines).
  • Also on file: Astaxanthin is rated "Insufficient Reliable Evidence To Rate" for Alzheimer disease, Parkinson disease.

The evidence we hold on astaxanthin for the claims it's often promoted for — age-related cognitive decline, macular degeneration, aging skin, Alzheimer disease, athletic performance, and carpal tunnel syndrome — is rated insufficient to establish whether it works. That doesn't mean it doesn't; it means the research so far hasn't been robust enough to say either way.

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, but long-term safety data are limited. The most commonly reported side effects are abdominal pain, diarrhea, and red-colored stools — the latter is a harmless effect of the pigment itself.

A small number of trial participants experienced increased bowel movements at lower doses and stomach pain at very high doses. There isn't enough safety data to know whether astaxanthin is safe in pregnancy or while breastfeeding.

If you're pregnant, planning pregnancy, or nursing, talk with your doctor or pharmacist before taking it to weigh what you know about your own 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.

Moderate-severity interactions are documented with drugs that your body breaks down via the CYP3A4 enzyme (a very large group that includes many statins, blood pressure medications, immunosuppressants, and others) and the CYP2B6 enzyme. These interactions have only been shown in lab studies, not in humans, but you should still verify your exact medications with your doctor or pharmacist before starting astaxanthin.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Astaxanthin is a single-ingredient supplement that's generally well tolerated short-term, though the evidence for what it actually does isn't established yet. The main thing to watch is that it may lower blood levels of medications your liver processes through two specific enzyme pathways — a concern backed by lab work but not yet proven in people.

Before you start, check your medications against the interaction tool on this page and talk it over with your doctor or pharmacist, especially if you're on any long-term prescriptions.

General Statements

THE PROOF Studies on anti-aging have uncovered astaxanthin’s unique ability to cross the blood-brain barrier. Clinical evidence suggests this powerful antioxidant may support and maintain a healthy central nervous system.

Found in salmon, trout and other red-pink marine life, this carotenoid helps supply dramatic cellular protection against oxidative stress. Astaxanthin is oil soluble, a unique trait allowing access into the central nervous system’s cellular structure to support brain and eye health. Drawn from one of the richest known natural sources – microalgae Haematococcus pluvialis – for potency and efficient assimilation.

Astaxanthin marine antioxidant helps support healthy aging, mobility and immune system

THE ART An alliance of science and nature delivers one of the world’s most vital marine carotenoid antioxidants. Advanced CO2 extraction and a patented closed cultivation process ensure purity.

THE BENEFITS Astaxanthin helps neutralize free radicals. With superior antioxidant strength, this carotenoid helps support DNA protection to promote healthy vision, skin, cardiovascular function and cognition.

Astaxanthin 8 mg by ResVitale: Common Questions

Does Astaxanthin 8 mg by ResVitale interact with any medications?
Yes. Based on its ingredients, Astaxanthin 8 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 8 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 either way. The facts advise caution in both pregnancy and lactation. Talk with your doctor or pharmacist about your specific situation before you take it.
What are the most common side effects?
Abdominal pain, diarrhea, and red-colored stools are the most commonly reported. The red stools are just the astaxanthin's color and harmless; they'll go away when you stop. Stomach upset tends to be mild in most people.
Does astaxanthin actually work for anti-aging or brain health?
The evidence we hold on astaxanthin for aging skin, age-related cognitive decline, macular degeneration, Alzheimer disease, athletic performance, and carpal tunnel syndrome is all rated insufficient — meaning the research hasn't been strong enough yet to say whether it works.
How long has astaxanthin been studied for safety?
Short-term studies show it's generally well tolerated, but long-term safety data are limited. That's why it's important to talk with your doctor or pharmacist if you're thinking of taking it regularly.
Why does it say 672 medications interact with this?
Astaxanthin may affect how your liver processes drugs through two enzyme pathways. Those pathways clear a large number of common medications — everything from blood pressure drugs to statins to some psychiatric medications. You'll want to check your specific prescriptions before starting.
