HelloPharmacist Scorecard of PhosphOmega Krill Oil 1000 mg by Wonder Laboratories

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 Sep 3, 2026

What’s inside

Partial disclosure
Ingredient Transparency · database check
Partial

Most active ingredients list an amount, but at least one is hidden in a blend or missing.

Why this rating?
  • The label discloses an exact amount for 6 of its 7 active ingredients.
  • “Krill Oil” is listed as a grouped ingredient — the label gives one combined amount (1,000 mg) without saying how much of each component you get.

PhosphOmega Krill Oil contains 7 active ingredients sourced from krill and omega-3 compounds. The main ones are two types of omega-3 fatty acids — eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) — plus astaxanthin, a pigment with antioxidant properties.

The product also delivers other omega-3 and omega-6 fatty acids and phospholipids, which are fat-like substances that help your body absorb and use these oils. The inactive ingredients are gelatin (the capsule shell), vegetable glycerin, vitamin E (D-alpha-tocopherol), and vitamin A (retinyl palmitate).

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 isn't established in our data for any of its claimed uses — age-related cognitive decline, macular degeneration, aging skin, Alzheimer disease, athletic performance, or carpal tunnel syndrome all carry a rating of insufficient reliable evidence. We have no effectiveness data on file for the other omega-3 and phospholipid ingredients in this product.

The evidence, ingredient by ingredient Krill Oil 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, but long-term safety studies are limited. The most common side effects reported were abdominal pain, diarrhea, and red-colored stools — a small number of trial participants at routine doses (6 mg daily) experienced increased bowel movements and red fecal color, while a higher dose (40 mg daily) caused severe stomach pain in two patients.

The safety data advises against using this product during pregnancy and while breastfeeding.

Side effects, ingredient by ingredient Krill Oil 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 this, double-check any medications you're on that are processed through your liver's CYP3A4 or CYP2B6 pathways, because astaxanthin may theoretically decrease their levels and reduce how well they work. This is a theoretical concern from lab research and hasn't been confirmed in people, but it's worth confirming with your doctor or pharmacist that your specific drugs won't be affected.

The bottom line

Scorecard at a glancePartially disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This is a krill oil supplement with astaxanthin, aimed at omega-3 intake and antioxidant support. If you take any medications metabolized by your liver — especially heart drugs, cancer medications, or immunosuppressants — check with your doctor or pharmacist before starting, because astaxanthin may theoretically lower their blood levels.

Pregnant or nursing? The safety data suggests skipping this one.

Talk it over with your own healthcare provider to see if it fits your situation.

Krill Oil2 drug types · 208 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, krill oil may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Taking high doses of omega-3 fatty acids from fish oil can modestly decrease platelet aggregation. Since krill oil also contains these fatty acids, taking high doses of krill oil might also inhibit platelet aggregation. Theoretically, taking high doses of krill oil with antiplatelet or anticoagulant drugs might increase the risk of bleeding. However, the omega-3 content of krill oil is much lower than that of fish oil.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, taking krill oil with antidiabetes drugs might increase the risk of hypoglycemia.
Some research in animals and humans shows that krill oil might lower blood glucose levels. However, a small study shows that taking krill oil does not reduce blood glucose levels in patients with type 2 diabetes, most of whom were taking antidiabetes drugs.

PhosphOmega Krill Oil 1000 mg by Wonder Laboratories: Common Questions

Does PhosphOmega Krill Oil 1000 mg by Wonder Laboratories interact with any medications?
Yes. Based on its ingredients, PhosphOmega Krill Oil 1000 mg has a known interaction with 838 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
PhosphOmega Krill Oil 1000 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 krill oil?
Astaxanthin is a pigment found naturally in krill and algae with antioxidant properties. It's included in this formula as an active ingredient, though the evidence for what it does for your body isn't well established yet.
Can I take this while pregnant or breastfeeding?
The safety data advises against it — there isn't enough information to know whether it's safe during pregnancy or while breastfeeding. Talk with your doctor or pharmacist about whether this supplement is right for you.
What side effects does astaxanthin cause?
Most people tolerate it well, but some trial participants reported abdominal pain, diarrhea, or red-colored stools. At higher doses (40 mg daily), a small number experienced severe stomach pain.
Will this help with brain fog or aging skin?
The evidence we have on file isn't strong enough to say astaxanthin works for age-related cognitive decline or aging skin. More research is needed before we can rate its effectiveness for these uses.
Does this product have fillers or binders?
Yes — in addition to the active omega-3 and astaxanthin ingredients, it contains gelatin (capsule shell), vegetable glycerin, vitamin E, and vitamin A as inactive ingredients.
