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 Algae Powder contains one active ingredient: astaxanthin, a natural carotenoid pigment sourced from algae. There are no added inactive ingredients in this formulation.

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 supporting astaxanthin for specific health claims hasn't been established in our data. The facts list potential uses—including age-related cognitive decline, macular degeneration, aging skin, Alzheimer's disease, athletic performance, and carpal tunnel syndrome—but each one is rated insufficient evidence to rate, meaning the research so far doesn't yet support a clear conclusion about whether it works for those purposes.

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 when taken orally are abdominal pain, diarrhea, and red or discolored stools.

Lower doses (6 mg daily) caused increased bowel movements and red fecal color in a small number of trial participants; a much higher dose (40 mg daily) caused severe stomach pain in two patients. The safety data advises against use during pregnancy and while breastfeeding, as there isn't enough research to confirm safety in those settings.

If you're pregnant, planning to become pregnant, or breastfeeding, talk with your doctor or pharmacist about whether this product is appropriate for you.

Astaxanthin Algae Powder by TerraVita Premium Collection: Common Questions

Does Astaxanthin Algae Powder by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Astaxanthin Algae Powder 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 Algae Powder 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's astaxanthin, and where does it come from?
Astaxanthin is a natural pigment called a carotenoid, sourced from algae in this product. It's the compound that gives certain sea creatures and algae their reddish color.
Is this supplement proven to work for anti-aging or brain health?
The research so far doesn't establish that astaxanthin reliably works for those purposes. The evidence for age-related cognitive decline, macular degeneration, aging skin, Alzheimer's disease, athletic performance, and carpal tunnel syndrome is all rated insufficient, meaning we don't yet have solid proof either way.
What side effects should I watch for?
Most people tolerate it well, but the most common side effects are abdominal pain, diarrhea, and discolored (often reddish) stools. Higher doses are linked to more severe stomach pain in rare cases.
Can I take this if I'm pregnant or breastfeeding?
The safety data advise against it during pregnancy and breastfeeding, since there isn't enough research to confirm safety. Talk with your doctor or pharmacist about your individual situation before starting.
Why does the product interact with so many medications?
Astaxanthin may theoretically speed up how your liver processes drugs through two enzymes (CYP3A4 and CYP2B6). Many common medications depend on these enzymes, so the interaction list is large—but your own medications may or may not be affected. Check them against the tool on this page.
