HelloPharmacist Scorecard of Hawaiian Astaxanthin by Health Ranger's

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.

Health Ranger's Hawaiian Astaxanthin is a single-ingredient supplement containing natural astaxanthin, a carotenoid (a type of antioxidant) derived from algae. The capsule itself contains inactive ingredients — sunflower oil, gelatin, glycerin, purified water, and vitamin E — which help deliver the astaxanthin to your body.

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: joint, skin, eye and cardiovascular health.
  • We looked for evidence on: Age-related macular degeneration (AMD), Aging skin, Dry eye, Exercise-induced muscle damage, Exercise-induced muscle soreness, Heart failure — 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, Heart failure, Dry eye, Exercise-induced muscle soreness, and more.

The data we hold on astaxanthin effectiveness shows insufficient evidence for age-related cognitive decline, age-related macular degeneration (a condition affecting the back of the eye), aging skin, Alzheimer disease, athletic performance, and carpal tunnel syndrome. In short, we don't have reliable evidence backing astaxanthin for these uses yet.

If you're considering it for one of these purposes, talk with your doctor or pharmacist about whether the research supports it for your 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 remain limited. The most common side effects reported are mild — abdominal discomfort, diarrhea, and red-colored stools.

At higher doses, a small number of people have reported more serious stomach or abdominal pain. There isn't enough safety data in pregnancy, so the data advises against using this supplement if you're pregnant.

The same applies to breastfeeding — there isn't enough information to know if it's safe, so talk with your doctor or pharmacist for personalized advice before taking it.

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 take Health Ranger's Hawaiian Astaxanthin, have a conversation with your doctor or pharmacist about any medications you're on that are processed through the liver enzymes CYP3A4 or CYP2B6. This includes many blood pressure drugs, cholesterol medications, immunosuppressants, and other common prescriptions — astaxanthin may lower their levels and reduce how well they work.

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.

This single-ingredient astaxanthin supplement may appeal to you if you're interested in antioxidant support, but be aware it could theoretically affect how your liver processes over 600 medications. If you take anything metabolized by CYP3A4 or CYP2B6 enzymes — a category that includes many common drugs — check with your doctor or pharmacist before starting.

Avoid it during pregnancy or breastfeeding without talking to your healthcare provider first.

Hawaiian Astaxanthin by Health Ranger's: Common Questions

Does Hawaiian Astaxanthin by Health Ranger's interact with any medications?
Yes. Based on its ingredients, Hawaiian 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?
Hawaiian 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.
Can I take this while I'm pregnant or breastfeeding?
There isn't enough safety data on astaxanthin in pregnancy or breastfeeding. The data advises against it in both cases. Talk with your doctor or pharmacist before starting this supplement if you're pregnant, planning to become pregnant, or breastfeeding — they can give you personalized advice based on your situation.
What does astaxanthin actually do?
Astaxanthin is a carotenoid antioxidant naturally found in algae and other marine sources. It's marketed for various aging and cognitive claims, but the evidence we hold shows insufficient data to rate it for age-related cognitive decline, macular degeneration, skin aging, Alzheimer disease, athletic performance, or carpal tunnel syndrome.
What are the side effects?
Most people tolerate it well. The most common side effects are mild — belly discomfort, diarrhea, and red-colored stools. At higher doses, a few people reported more severe stomach pain. Long-term safety data are limited, so we don't know what happens with very prolonged use.
Does this product have fillers?
Yes. Besides the active astaxanthin, the capsule contains sunflower oil, gelatin, glycerin, purified water, and vitamin E as inactive ingredients to deliver and preserve the supplement.
How much astaxanthin is in each capsule?
The product facts provided don't specify the dose per capsule. Check the label on your bottle for that information.
