Nattokinase & Serratiopeptidase Enzyme Blend
Supports Healthy Blood Flow & Circulation
Promotes Vascular & Capillary Health

Healthy circulation is quiet work your body does every second — until it isn't. Nattokinase Plus pairs nattokinase, a fibrinolytic enzyme from fermented soy, with serratiopeptidase and the antioxidant rutin to support healthy blood flow, capillary strength, and vascular health. It is vitamin K-free, so it fits alongside more supplement routines.

If you take anticoagulant medication (such as warfarin) or have a clotting disorder, do not use this product without your provider's guidance.
Nattokinase is an enzyme traditionally derived from natto, a Japanese fermented soy food, studied for supporting the body's normal breakdown of fibrin and healthy blood flow. Serratiopeptidase adds a second enzyme, and rutin — a flavonoid antioxidant — supports capillary strength. The formula is made without vitamin K.
Take 2 capsules daily between meals, or as directed by your healthcare practitioner.
