HelloPharmacist Scorecard of Astaxanthin Gold 4 mg by NutriGold

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 16, 2026

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.

Astaxanthin Gold contains one active ingredient: astaxanthin (supplied as AstaReal), a carotenoid — a naturally occurring pigment found in certain algae and seafood. Each softgel delivers 4 mg.

The capsule also contains inactive ingredients: extra virgin olive oil, bovine gelatin, glycerin, and water.

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: supports energy, endurance, eye, joint, skin, immune, and heart health.
  • We looked for evidence on: Age-related macular degeneration (AMD), Aging skin, Athletic performance, Dry eye, Exercise-induced muscle damage, Exercise-induced muscle soreness — and 4 related terms.
  • The closest evidence on file: Astaxanthin is rated "Insufficient Reliable Evidence To Rate" for Age-related macular degeneration (AMD) (Natural Medicines).
  • Also on file: Astaxanthin is rated "Insufficient Reliable Evidence To Rate" for Aging skin, Athletic performance, Heart failure, Dry eye, and more.

The evidence for astaxanthin isn't established yet in our data. The product is marketed for age-related cognitive decline, macular degeneration, aging skin, Alzheimer disease, athletic performance, and carpal tunnel syndrome, but we hold insufficient reliable evidence to rate how well it works for any of these uses.

Talk with your doctor about whether it's a reasonable choice for your particular situation.

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 mild: abdominal pain, diarrhea, and red-colored stools (which are harmless — it's just the pigment).

At much higher doses (40 mg daily), severe stomach pain has been reported in a small number of people. There isn't enough safety data to know whether it's okay during pregnancy or while breastfeeding.

If you're pregnant, planning pregnancy, or nursing, talk with your doctor or pharmacist about whether this product is right for you.

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 doctor or pharmacist if you're on any medications broken down by CYP3A4 or CYP2B6 enzymes — these are Moderate-severity interactions. Your pharmacist can use the search tool on this page to look up your specific drugs and flag any concerns.

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 Gold may appeal to you if you're interested in antioxidant support, but the evidence for its benefits hasn't been established in our data. The main caution is a theoretical interaction with medications processed by your liver — check your exact prescriptions with your pharmacist or doctor before starting.

If you're pregnant or breastfeeding, there's not enough safety information, so discuss it with your healthcare provider first.

Astaxanthin Gold 4 mg by NutriGold: Common Questions

Does Astaxanthin Gold 4 mg by NutriGold interact with any medications?
Yes. Based on its ingredients, Astaxanthin Gold 4 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 Gold 4 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 if I'm pregnant or breastfeeding?
There isn't enough safety data to say whether it's okay to use during pregnancy or while breastfeeding. Talk with your doctor or pharmacist before taking it if you're pregnant, planning to become pregnant, or nursing.
What side effects might I notice?
Most people tolerate it well. The most common side effects are mild — abdominal pain, diarrhea, or red-colored stools (which is just the pigment passing through). At very high doses, severe stomach pain has been reported in a small number of people.
Does astaxanthin actually work for aging skin or brain health?
The evidence in our data is insufficient to rate how well it works for these uses. While it's marketed for age-related cognitive decline, macular degeneration, and aging skin, we don't have reliable evidence to say whether it delivers on those claims.
What is astaxanthin?
It's a carotenoid — a natural pigment found in certain algae and seafood. It acts as an antioxidant in your body, which is why it's included in many wellness supplements.
How long can I safely take this product?
Long-term safety data are limited, so we don't have solid information on how long it's okay to use. It's something worth discussing with your doctor or pharmacist if you're thinking of taking it long-term.
