Nattokinase

Nattokinase is an enzyme extracted from natto, a traditional Japanese food made from fermented soybeans. It supports healthy circulation and normal blood flow by helping maintain healthy blood viscosity. Nattokinase has become one of the most popular enzymes for cardiovascular support.

This collection includes nattokinase capsules from 50 to 100 mg, the clinically studied NSK-SD form and nattokinase combination formulas from practitioner brands such as Xymogen, Klaire Labs, Pure Encapsulations, Allergy Research Group, Protocol for Life Balance, Progressive Labs, Ecological Formulas and Enzyme Science.

How to Choose a Nattokinase Supplement

• NSK-SD: A standardized, vitamin K2-free nattokinase. NSK-SD by Pure Encapsulations and Nattokinase NSK-SD by Klaire Labs are popular picks.
• Dose: Most products provide 50 to 100 mg, often listed in fibrinolytic units (FU). Nattokinase 100 mg by Xymogen is our top seller.
• Vitamin K2-free: Natto is naturally rich in vitamin K2, so most supplements remove it. Check the label if this matters to you.
• Combination formulas: Some pair nattokinase with vitamin E or other circulation nutrients.

Nattokinase is usually taken on an empty stomach, often split into two doses. Do not combine it with blood thinners or aspirin unless your practitioner approves, and stop taking it at least two weeks before surgery. See also heart health and enzymes.
