HelloPharmacist Scorecard of Triple Strength Astaxanthin 12 mg by NOW

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.

This product contains one active ingredient: astaxanthin 12 mg per softgel (supplied as AstaReal). Astaxanthin is a natural red pigment and antioxidant found in certain marine organisms and algae.

The remaining ingredients are inactive — corn starch, glycerin, water, carrageenan, sorbitol, extra virgin olive oil, and vitamin E (as d-alpha-tocopherol and mixed tocopherols) — which serve as capsule material, thickeners, and preservatives.

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: brain health and eye health support.
  • We looked for evidence on: Age-related cognitive decline, Age-related macular degeneration (AMD), Dry eye, Eye strain, Cognitive function, Antioxidant protection.
  • The closest evidence on file: Astaxanthin is rated "Insufficient Reliable Evidence To Rate" for Age-related cognitive decline (Natural Medicines).
  • Also on file: Astaxanthin is rated "Insufficient Reliable Evidence To Rate" for Age-related macular degeneration (AMD), Dry eye.

The evidence we hold on astaxanthin for its most common uses — age-related cognitive decline, macular degeneration, aging skin, Alzheimer disease, athletic performance, and carpal tunnel syndrome — is insufficient to rate. That means existing studies aren't strong enough to say whether astaxanthin actually works for these 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 are limited. The most common side effects reported are abdominal pain, diarrhea, and red-colored stools.

At the standard 12 mg dose, these are uncommon; higher doses (40 mg daily) have caused severe stomach pain in isolated cases. There isn't enough safety data to know whether astaxanthin is safe in pregnancy or while breastfeeding — talk with your doctor or pharmacist for personalized advice 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 astaxanthin supplement, check with your doctor or pharmacist if you take any medications metabolized by the CYP3A4 or CYP2B6 enzymes — these include many heart medications, immunosuppressants, and certain cancer drugs. Astaxanthin may theoretically speed up how your body clears these medications (Moderate severity for both groups), though this effect has only been seen in lab studies, not in actual patients.

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 is a natural antioxidant that's generally well tolerated, but evidence for its benefits isn't established yet. If you take medications processed by your liver, especially common heart drugs or immunosuppressants, check with your doctor or pharmacist before starting — lab studies suggest it might lower their levels, though this hasn't been proven in people.

Avoid it in pregnancy and while breastfeeding unless advised otherwise by your healthcare provider.

Formula

Astaxanthin is a naturally occurring carotenoid derived from non-GMO Haematococcus pluvialis microalgae. Due to its unique structure, astaxanthin plays an important role in cellular free radical protection and healthy immune system responses. Astaxanthin has been shown in clinical studies to promote normal cognitive function and may help to maintain a positive mood in adults. In the eye, it helps to neutralize free radicals and helps manage eyestrain due to computer usage.

This triple strength product has three times the Astaxanthin (12 mg per softgel) than our regular strength product (4 mg per softgel).

Triple Strength Astaxanthin 12 mg by NOW: Common Questions

Does Triple Strength Astaxanthin 12 mg by NOW interact with any medications?
Yes. Based on its ingredients, Triple Strength Astaxanthin 12 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?
Triple Strength Astaxanthin 12 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.
What is astaxanthin, and why is it in this product?
Astaxanthin is a natural red pigment and antioxidant from marine sources like algae. It's included in this supplement because people have explored its potential for aging-related eye and cognitive health, but we don't yet have strong enough evidence to confirm it works for those purposes.
Are there any common side effects I should expect?
Most people tolerate astaxanthin well. The side effects that have shown up in studies are mild — abdominal pain, diarrhea, and red-colored stools. They're uncommon at the 12 mg dose in this product.
Can I take this while pregnant or breastfeeding?
There isn't enough safety data to know either way. The safety data advises against use during pregnancy and breastfeeding. Talk with your doctor or pharmacist about whether it's right for you in these situations.
Does this product actually work for anti-aging or eye health?
The evidence we hold isn't strong enough to say. For age-related cognitive decline, macular degeneration, aging skin, and other common claims, the research hasn't been conclusive enough to rate it as effective.
How long has astaxanthin been studied for safety?
While astaxanthin is generally well tolerated in the studies we have, long-term safety data are limited. We don't have decades of follow-up data on everyday use.
Are there any inactive ingredients I should know about?
The softgel contains corn starch, glycerin, water, carrageenan, sorbitol, extra virgin olive oil, and vitamin E. If you're sensitive to any of these, check the label or talk with your pharmacist.
