HelloPharmacist Scorecard of Astaxanthin 6 mg by Designs for Health

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.

This product contains one active ingredient: Natural Astaxanthin, a carotenoid (plant pigment) at 6 mg per softgel. The inactive ingredients are olive oil, gelatin, glycerine, and purified water — these serve as the carrier, capsule material, and preservatives to hold the supplement together.

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 we hold for astaxanthin doesn't yet support claims about its effectiveness. Research is insufficient to rate it for age-related cognitive decline, macular degeneration, aging skin, Alzheimer disease, athletic performance, or carpal tunnel syndrome.

More reliable data would be needed to know whether it delivers real benefits for these uses.

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 at 6 mg daily is generally well tolerated, though long-term safety data are limited. The most common side effects reported in studies are abdominal pain, diarrhea, and red-colored stools.

A small number of trial participants taking this dose experienced increased bowel movements and red fecal color; higher doses have caused more severe stomach pain in some cases. Because there isn't enough safety data, the data advises against use during pregnancy and while breastfeeding — talk with your doctor or pharmacist for personalized guidance if you're pregnant, planning pregnancy, or nursing.

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 take medications metabolized by the liver enzymes CYP3A4 or CYP2B6 — this includes many statins, some blood pressure and heart medications, immunosuppressants, and other drugs. These are Moderate-severity interactions based on test-tube data, though they haven't been confirmed in patients yet.

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 generally well tolerated at this dose, but we don't yet have reliable evidence it works for the conditions it's often marketed for. The main caution is a theoretical interaction with medications broken down by your liver — something to confirm with your doctor or pharmacist before you start, especially if you take statins, blood pressure drugs, or immunosuppressants.

It's not advised during pregnancy or breastfeeding without talking to your healthcare provider first.

How much long-term safety data exists for this supplement?
Long-term safety data are limited. While short-term studies show it's generally well tolerated, we don't have extensive information about safety with years of daily use.
