What Is Nattokinase?

Nattokinase is an enzyme originally identified in natto, a traditional Japanese food produced by fermenting soybeans with Bacillus subtilis.

Unlike many nutritional ingredients measured simply by weight, nattokinase is commonly standardised according to its enzymatic activity, expressed in fibrinolytic units (FU).

Each Doctor’s Best capsule provides 2,000 FU.

Circulatory Support

Nattokinase has attracted scientific interest because of its fibrinolytic activity and potential role in supporting normal blood circulation.

Doctor’s Best specifically positions the formula to:

• Support the circulatory system
• Help maintain normal fibrinogen levels in the blood
• Support overall cardiovascular health

Fibrin is a protein involved in the body's normal blood-clotting process, while fibrinogen is its circulating precursor.

Vitamin K2 Removed

Natto naturally contains vitamin K2, but the nattokinase used in this formula has had vitamin K2 removed.

This allows the product to provide standardised nattokinase enzyme activity without supplying the naturally occurring K2 associated with traditional natto.

This does not mean the product is appropriate to combine with anticoagulant medication. The manufacturer specifically advises against its use by people taking anticoagulants.
