Why this scored 62/100
2,000 FU per serving is the standard studied dose for nattokinase's mild fibrinolytic and blood-pressure effects (Kim 2008 hypertension pilot; Chen 2018 meta). Activity is quantified in fibrinolytic units, which is the correct disclosure for this enzyme. Safety is depressed because nattokinase can potentiate anticoagulants (warfarin, DOACs) and antiplatelets, and the SKU does not carry a prominent do-not-combine-with-blood-thinner warning. Would move to Verified 70+ with prominent anticoagulant-interaction disclosure and named NSK-SD or JBSL enzyme source.

Evidence & sources
The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.
Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.
How to read the Evidence dimension
- 80–100: Multiple double-blind RCTs in indexed journals directly testing this product OR the exact ingredients at the exact dose.
- 60–79: Single double-blind RCT + supporting ingredient literature at the studied dose.
- 40–59: Open-label trials + ingredient literature; no product-specific double-blind evidence.
- 20–39: Ingredient literature only; no product-specific trials or trials in predatory venues.
- 0–19: No credible evidence base or unverifiable claims.
Frequently asked questions
Auto-generated from Vyvata's scoring data for this product. For general questions about the store (shipping, returns, wholesale), see the site FAQ.
What is Nattokinase 2,000 Fibrinolytic Units?
Nattokinase 2,000 Fibrinolytic Units, categorized under Cardiovascular & heart health in the Supplements vertical. It is scored on the Vyvata Scoring Framework — an independent 6-dimension rubric applied uniformly to every product Vyvata lists.
How does Nattokinase 2,000 Fibrinolytic Units score on the Vyvata rubric?

Why did Nattokinase 2,000 Fibrinolytic Units score in the Standard tier?
2,000 FU per serving is the standard studied dose for nattokinase's mild fibrinolytic and blood-pressure effects (Kim 2008 hypertension pilot; Chen 2018 meta). Activity is quantified in fibrinolytic units, which is the correct disclosure for this enzyme. Safety is depressed because nattokinase can potentiate anticoagulants (warfarin, DOACs) and antiplatelets, and the SKU does not carry a prominent do-not-combine-with-blood-thinner warning. Would move to Verified 70+ with prominent anticoagulant-interaction disclosure and named NSK-SD or JBSL enzyme source.
What are the strongest and weakest aspects of this product?
Strongest: Transparency at 68/100 (dose disclosure vs proprietary blends, and honesty of marketing claims) and Formulation at 66/100 (dose adequacy, bioavailability form, and ingredient redundancy). Weakest: Safety at 55/100 (adverse-event profile, interaction risk, and dose ceiling) and Sustainability at 50/100 (sourcing practices, packaging, and corporate practice). All six dimensions feed the overall Vyvata score; a weakness on any one dimension pulls the overall down proportionally.
Is Nattokinase 2,000 Fibrinolytic Units third-party tested?
No third-party certifications (NSF, USP, ConsumerLab, or equivalent) were on record at the time of scoring. This affects the Manufacturing dimension score. The manufacturer may test internally or have obtained certification more recently — check the current product label for the most up-to-date information.
What would move Nattokinase 2,000 Fibrinolytic Units to a higher tier?
Would move to Verified 70+ with prominent anticoagulant-interaction disclosure and named NSK-SD or JBSL enzyme source.
