Nattokinase by Seeking Health provides nattokinase, a unique enzyme derived from natto, a popular Japanese fermented soy product. Nattokinase may play a role in supporting cardiovascular function by promoting healthy clotting activity and circulation. Each vegetarian capsule provides 100 mg of NSK-SD®, a patented, non-GMO form of nattokinase.*

Nattokinase may help support the body’s normal activity of breaking down the fibrin component of blood clots. Since small clots are formed continually throughout the body following injury to a blood vessel wall, the removal of unneeded clots is a crucial part of the healing process. In addition to this favorable fibrinolytic activity, Nattokinase may also have implications for healthy blood flow by supporting normal red blood cell aggregation and blood viscosity.*

This product is free of vitamin K.*

Suggested Use

Use is contraindicated in persons with history of bleeding tendency. Consult with your healthcare practitioner before use if you are taking blood thinning medication (e.g. warfarin or high-dose aspirin), have a blood coagulation condition or other medical condition, or are planning to have surgery.

Helped me
I am sad that this product is being discontinued. It has helped me greatly. I am unable to take pharmaceutical blood thinners due to bad reactions. Review by Barbara (Posted on 7/27/2018)
Sad Product is Being Discontinued
I have been looking to buy this product for a while but could not find a trusted source. I finally found it here and it's only available while supplies last. I am very sad to see this product be discontinued. Review by Erika (Posted on 4/4/2018)
Easy To Take, High Quality
Not easy to tell with this one if it's working, but it's very easy to swallow and there's no perceivable bad side effects. As always, the quality of these supplement seems to be top notch. Review by Alicia (Posted on 8/4/2015)
