HelloPharmacist Scorecard of NattoKinase Patented by Symbiotics

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 Aug 27, 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 1 of its 2 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (50 mg) without saying how much of each component you get.

NattoKinase Patented contains two active ingredients: nattokinase, an enzyme extracted from fermented soy, and BIO-lipid, for which we hold no detailed information. The product is packaged in gelatin capsules.

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 Nattokinase's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: maintains normal blood pressure and circulation.
  • We looked for evidence on: Hypertension, Cardiovascular disease (CVD), Atherosclerosis, Peripheral arterial disease (PAD), Venous insufficiency, Stroke — and 3 related terms.
  • The closest evidence on file: Nattokinase is rated "Insufficient Reliable Evidence To Rate" for Atherosclerosis (Natural Medicines).
  • Also on file: Nattokinase is rated "Insufficient Reliable Evidence To Rate" for Cardiovascular disease (CVD), Hypertension, Peripheral arterial disease (PAD), Stroke, and more.

The evidence we hold on nattokinase does not establish that it reliably works for angina, atherosclerosis, cancer, cardiovascular disease, or chronic fatigue syndrome — all are rated insufficient reliable evidence. If you're considering this product for one of these conditions, talk it over with your doctor to weigh what we know against other options.

The evidence, ingredient by ingredient Nattokinase

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.

Nattokinase is generally well tolerated short-term, but because it thins the blood, it carries risk for anyone prone to bleeding. The facts note rare reports of bleeding, including one case of brain hemorrhage when nattokinase was combined with aspirin.

Additionally, nattokinase can trigger allergic reactions in people sensitive to fermented soy (natto), ranging from throat symptoms to anaphylaxis — reactions typically appear within 2 hours of taking it. The safety data advises against nattokinase during pregnancy and while breastfeeding because there isn't enough information to know it's safe in those states.

If you're pregnant, planning pregnancy, or nursing, talk with your doctor or pharmacist before using this product.

Side effects, ingredient by ingredient Nattokinase

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 — Nattokinase.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 289 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.

Check your medications with your pharmacist or doctor before taking this product if you use blood thinners (anticoagulants like warfarin, or antiplatelets like aspirin or clopidogrel) — nattokinase increases bleeding risk (Moderate severity). Also check if you take blood pressure medications (antihypertensives) — nattokinase may lower pressure further (Moderate severity).

The bottom line

Scorecard at a glancePartially disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

This product is for adults interested in nattokinase's cardiovascular effects, but evidence for most claimed uses is insufficient. If you take blood pressure or blood clotting medications, you must check your exact drugs with your pharmacist or doctor before starting — the bleeding risk is real.

Anyone with a history of bleeding, a soy allergy, or who is pregnant or breastfeeding should avoid it.

NattoKinase Patented by Symbiotics: Common Questions

Does NattoKinase Patented by Symbiotics interact with any medications?
Yes. Based on its ingredients, NattoKinase Patented has a known interaction with 289 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
NattoKinase Patented contains 2 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 is nattokinase, and where does it come from?
Nattokinase is an enzyme extracted from natto, a traditional Japanese food made from fermented soybeans. It's the active ingredient in this product.
Can I take this if I'm allergic to soy?
No. Nattokinase comes from fermented soy and can trigger allergic reactions in people sensitive to natto, from throat swelling to severe reactions. If you have a soy allergy, avoid this product.
Is nattokinase safe during pregnancy or while breastfeeding?
The safety data advises against it — there isn't enough information during pregnancy, and safety while breastfeeding is unknown. Talk with your doctor or pharmacist before using it if you're pregnant, planning pregnancy, or nursing.
What does the research show nattokinase actually does?
The evidence we hold doesn't establish that nattokinase reliably works for heart disease, angina, cancer, atherosclerosis, or chronic fatigue — all lack sufficient reliable evidence. If you're considering it for one of these, ask your doctor what the current evidence supports.
Why is there a warning about combining this with aspirin?
Nattokinase thins the blood, and there's a documented case of brain bleeding in someone who took it while on low-dose aspirin. Combining blood-thinning substances raises the risk of serious bleeding.
