Description

Nattokinase is one of many different enzymes isolated from the fermented food product known as Natt? (fermented, boiled soybeans). Nattokinase has become popular as a supplement in recent years due to its fibrinolytic properties allowing it to degrade fibrin which can help support healthy blood flow and overall cardiovascular health.

Nattokinase varies in potency from 1000 FU/100 mg to 2000 FU/100 mg, FU stands for fibrin units which as an activity unit quantifying the ability of a given Nattokinase supplement to degrade fibrin. Our Nattokinase supplement is highly potent at 2000 FU/100 mg per capsule.

Frequently Asked Questions

What does nattokinase do for the body?

Nattokinase is an enzyme that supports cardiovascular health by promoting healthy blood flow and helping to break down fibrin, a protein involved in blood clot formation. It may also aid in reducing blood pressure and improving overall circulation.

How much nattokinase should be taken per day?

The recommended daily dosage of nattokinase is typically 100 to 200 mg, providing around 2,000 to 4,000 fibrinolytic units (FU). It’s best to follow product guidelines and consult a healthcare provider for personalized advice.

How should nattokinase be taken, and when is the best time to take it?

Nattokinase should be taken on an empty stomach, either 30 minutes before meals or 2 hours after eating, to ensure optimal absorption. The best time to take it depends on personal routine, but many prefer morning or evening for consistency.

Why should nattokinase be taken on an empty stomach?

Nattokinase should be taken on an empty stomach to prevent interference from digestive enzymes and food, ensuring it remains active in the bloodstream to effectively support cardiovascular health and fibrin breakdown.

How long does nattokinase stay in your system?

Nattokinase typically stays active in the system for 8 to 12 hours, depending on individual metabolism and dosage. For consistent benefits, it’s often taken twice daily.

Is Double Wood Nattokinase third-party tested?

Yes. Every batch is third-party tested by an ISO/IEC 17025-accredited laboratory for identity, enzymatic activity, heavy metals, and microbial safety. Nattokinase activity is verified in fibrin units (FU) — the industry-standard measure of enzymatic potency — using a fibrin plate assay against reference standards. The full COA panel also covers four heavy metals via ICP-MS (arsenic, cadmium, lead, mercury against USP <2232> limits) and six microbial screens (Total Plate Count, Yeast & Mold, Coliform, E. coli, Salmonella, Staphylococcus aureus per USP and AOAC methods). Manufactured in a cGMP-certified U.S. facility from globally sourced ingredients.

What does the Nattokinase Certificate of Analysis confirm?

The COA verifies 2,000 FU (fibrin units) of nattokinase enzymatic activity per capsule, the dose used in published cardiovascular research on nattokinase. Activity is measured by fibrin plate assay against reference enzyme standards. Heavy metals: arsenic, cadmium, lead, mercury all below USP <2232> daily-intake limits by ICP-MS. Microbial counts within USP <2021>/<2022> specifications; E. coli, Salmonella, and Staphylococcus aureus confirmed Absent. The current batch COA is linked above for verification against your bottle's lot number.
