HelloPharmacist Scorecard of Finest Pure Krill Oil by Pharmax

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

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 5 of its 5 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 5 active ingredients centered on omega-3s and a potent antioxidant. You're getting eicosapentaenoic acid and docosahexaenoic acid — the two main omega-3 fatty acids from krill — along with phospholipids and total omega-3 fatty acids that make up the oil's structure.

The fifth ingredient is esterized astaxanthin, a carotenoid pigment from krill that acts as an antioxidant. The capsule itself is made from fish gelatin.

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's effectiveness is limited. For age-related cognitive decline, age-related macular degeneration (AMD), aging skin, Alzheimer disease, athletic performance, and carpal tunnel syndrome, the data we hold shows insufficient reliable evidence to rate whether it works.

The omega-3 components of krill oil (eicosapentaenoic acid and docosahexaenoic acid) may have established roles, but their specific effectiveness ratings aren't detailed in this product's facts.

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.

Orally, astaxanthin is generally well tolerated in studies, though long-term safety data are limited. The most common side effects in trials were abdominal pain, diarrhea, and red-colored stools — a harmless effect from the pigment itself.

At lower doses (6 mg daily), a small number of people reported increased bowel movements and red fecal color; at much higher doses (40 mg daily), a small number experienced severe stomach or abdominal pain. Regarding pregnancy and breastfeeding: there isn't enough safety data for astaxanthin, so the safety data advises against use during pregnancy and while breastfeeding.

We hold no pregnancy or breastfeeding safety information for the other four ingredients.

Side effects, ingredient by ingredient Astaxanthin

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 you take Pharmax Finest Pure Krill Oil, check with your pharmacist or doctor if you're on any drugs metabolized by the liver enzyme CYP3A4 (Moderate severity) or CYP2B6 (Moderate severity). The astaxanthin in this product may theoretically decrease how your body clears these medications, though this hasn't been confirmed in people.

The other four ingredients have no documented interactions we could find, but confirmation of no harm is not guaranteed.

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.

This krill oil supplement is centered on omega-3 fatty acids and astaxanthin, an antioxidant. If you take medications metabolized by the liver enzymes CYP3A4 or CYP2B6 — a large group — you'll want to check your exact prescriptions before starting.

If you're pregnant or breastfeeding, talk with your doctor or pharmacist about whether astaxanthin is right for you, given the limited safety data.

Finest Pure Krill Oil by Pharmax: Common Questions

Does Finest Pure Krill Oil by Pharmax interact with any medications?
Yes. Based on its ingredients, Finest Pure Krill Oil 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?
Finest Pure Krill Oil contains 5 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 does astaxanthin actually do?
Astaxanthin is an antioxidant pigment — it's what gives krill their reddish color. We hold insufficient evidence to rate whether it helps with age-related cognitive decline, macular degeneration, skin aging, Alzheimer disease, athletic performance, or carpal tunnel syndrome.
Will this turn my poop red?
It might. Red-colored stools are a harmless side effect of the astaxanthin pigment itself and were reported in a small number of trial participants at lower doses. It's not blood — just the pigment passing through.
Is it safe to take while pregnant or breastfeeding?
There isn't enough safety data for astaxanthin during pregnancy or breastfeeding, so the safety data advises against it. Talk with your doctor or pharmacist about your specific situation to decide what's right for you.
What are the omega-3s in here doing?
The two main omega-3 fatty acids — eicosapentaenoic acid and docosahexaenoic acid — are the active components krill oil is known for. Their specific roles and benefits aren't detailed in this product's facts.
Can I take this with my liver medications?
That depends on which ones. Astaxanthin may theoretically lower levels of medications metabolized by CYP3A4 or CYP2B6 liver enzymes — a very large category. Use the drug search tool on this page to check your prescriptions, then confirm with your doctor or pharmacist before you start.
What if I get stomach pain or diarrhea?
Abdominal pain and diarrhea were the most common side effects in studies. Most people tolerated it well, but a small number at higher doses experienced severe stomach pain. If it's severe or doesn't settle, stop and talk to your pharmacist.
