Natural fibrinolytic support for healthy circulation, backed by clinical research and standardized quality.* What It Does Nattokinase NSK-SD® promotes the body’s natural fibrinolytic processes to support healthy blood flow, circulation, and normal clotting mechanisms.* It helps maintain cardiovascular health by breaking down fibrin and enhancing the body’s natural plasminogen activation.* Clinical studies show its benefits for healthy circulation and balanced lipid metabolism within normal limits.* Originally discovered for its strong proteolytic, systemic enzyme activity, it supports healthy circulation and normal clotting mechanisms.* ARG offers Nattokinase NSK-SD in 100 mg (2000 FU) and 50 mg (1000 FU). How It Works Nattokinase: A proteolytic, systemic enzyme derived from Bacillus subtilis during the fermentation of soybeans, discovered for its potent fibrinolytic activity stronger than plasmin or elastase in vivo.* [1] •    Fibrinolytic Support: Nattokinase enhances the breakdown of fibrin and stimulates plasminogen activators, contributing to healthy blood flow and normal clotting.* [2] •    Clinical Evidence: Trials demonstrate that daily supplementation with nattokinase supports circulation, clotting regulation, and lipid metabolism over periods ranging from 2 months to 12 months.* [3-5] •    Prolonged Activity: Nattokinase's fibrinolytic, proteolytic systemic enzyme effects have been observed to last between 8 to 12 hours after ingestion.* [2] Who It’s For Ideal for individuals seeking to support healthy circulation, cardiovascular function, and normal clotting processes naturally.* Suitable for those interested in maintaining vascular health, especially during periods of metabolic or age-related circulatory changes.* Special Features Authenticity and Standardization: Nattokinase NSK-SD® is the first nattokinase introduced into the U.S. market, with established standardization, safety, and potency protocols.* •    Superior Quality: Produced from non-GMO soybeans using a patented strain of Bacillus subtilis natto, NSK-SD® is non-irradiated, and free of vitamin K2.* •    Global Recognition: Supported by two Japanese and three U.S. patents and recognized by JHFA and JNKA for authenticity and quality.* [6-7] Support proteolytic, systemic enzyme, and fibrinolytic activity to address cardiovascular wellness with the clinically studied and globally trusted Nattokinase NSK-SD.®* References ¹ Chen H, et al.
