HelloPharmacist Scorecard of Natural Double Strength Astaxanthin by Nature's Vision

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 Aug 27, 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.

This product contains one active ingredient: astaxanthin powder. Astaxanthin is a carotenoid (a natural pigment) sourced from algae and other organisms.

The tablet also includes several inactive ingredients — dicalcium phosphate, microcrystalline cellulose, stearic acid, silicon dioxide, magnesium stearate, and phospholipids — which are used as binders, fillers, and to form the tablet.

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.

The evidence for astaxanthin is currently insufficient to make a reliable claim about its benefits. The data we hold covers age-related cognitive decline, age-related macular degeneration (AMD), aging skin, Alzheimer disease, athletic performance, and carpal tunnel syndrome — and for all of these, we do not have enough reliable evidence to rate whether it works.

You may want to talk with your doctor about what you're hoping to achieve and whether there are other options with stronger evidence behind them.

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 — a harmless color change from the supplement itself.

At typical doses (6 mg daily), these effects are mild; at much higher doses (40 mg daily), a small number of people have reported severe stomach pain. Because there isn't enough safety data, you should avoid this supplement during pregnancy or while breastfeeding — talk with your doctor or pharmacist if you're in either situation and looking for an alternative.

Meds to double-check

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 doctor or pharmacist about any medications you take that are processed by your liver's CYP3A4 or CYP2B6 enzymes. These are Moderate-severity interactions: astaxanthin may speed up how your body breaks down these drugs.

This effect has been observed in lab studies but not yet confirmed in humans — that doesn't mean it won't happen, so it's worth a quick verification.

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.

Natural Double Strength Astaxanthin may be worth considering if you're interested in antioxidant support, but the evidence for specific health claims isn't established yet. If you take any prescription medications, especially ones your doctor has adjusted to a particular dose, check with your pharmacist or doctor before starting it — the supplement may affect how some drugs work.

Pregnancy and breastfeeding are not the right time for this product, so discuss your options with your healthcare provider if that applies to you.

Natural Double Strength Astaxanthin by Nature's Vision: Common Questions

Does Natural Double Strength Astaxanthin by Nature's Vision interact with any medications?
Yes. Based on its ingredients, Natural Double Strength Astaxanthin 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?
Natural Double Strength Astaxanthin 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 and similar organisms — that your body uses as an antioxidant. It's what gives salmon and shrimp their pink color.
What side effects should I watch for?
The most common side effects are stomach pain, diarrhea, and red-colored stools. The red color is harmless and just from the supplement itself. At the doses in this product, these effects are usually mild; if you experience severe stomach pain, stop and contact your doctor.
Can I take this if I'm pregnant or breastfeeding?
No — there isn't enough safety data, so it's best to avoid astaxanthin during pregnancy and while breastfeeding. Talk with your doctor or pharmacist about safer options for you.
Does astaxanthin actually work for anti-aging or eye health?
The evidence we have isn't strong enough to say either way. For age-related macular degeneration (AMD), aging skin, cognitive decline, and other uses listed on the product, we don't have reliable data yet. Your doctor can discuss whether it's a reasonable choice for what you're hoping to achieve.
Will this interact with my blood pressure or cholesterol medication?
Possibly — many of those drugs are processed by the CYP3A4 enzyme, which astaxanthin may speed up. This could make your medication less effective. Check with your pharmacist or doctor before you start, especially if your dose has been fine-tuned over time.
