Unique features of NSK-SD®

Nattokinase NSK-SD® is the No. 1 most researched nattokinase (> 35 studies) developed by Japan Bio Science Laboratory, the leader and pioneer in nattokinase. It is the industry’s only nattokinase ingredient fermented from the original Bacillus subtilis natto strain and extracted via a proprietary process (Patents JP3834048, JP3881494), resulting in maximal yield and potency. Besides, NSK-SD® is also the first nattokinase introduced into the US market.  Other unique features of NSK-SD® are:

Authentic nattokinase

as recognized by JHFA (Japan Health and Nutrition Food Association) and JNKA (Japan NattoKinase Association)

Did you know?

There are counterfeit nattokinase in the market!

Nattokinase is a distinctive enzyme that can be distinguished from other closely resembled enzymes by analysing Oxidised Insulin Chain B Degradation Pattern. From the results below, we would notice that some products labelled as “nattokinase” are not the genuine nattokinase, but they are some other enzymes, which have questionable efficacy. To be on the safe side, always look out for NSK-SD® when choosing nattokinase supplements.

Clinically proven safe and effective

Backed by more than 35 research studies and 20-year selling history (as of 2019) with no safety issues.

Halal & NSF certified

Compliance with GMP & meet strict standards for public health protection

Patented production technology

Awarded 2 Japanese patents and 3 U.S. patents for the proprietary processing technique

Natural & vegetarian

Non-irradiated, free of vitamin K2, purine and pungent smell

  • Vitamin K2: High concentrations of vitamin K2 in natto may increase blood coagulation, as well as decrease the effect of warfarin (blood thinner). This may also happen with nattokinase supplements if vitamin K2 is not removed during the production process. Hence, all vitamin K2 has been removed from nattokinase NSK-SD® via a proprietary technology.
  • Purine: Natto is high in purine and may not be suitable for those with high blood uric acid and gout. If too much purine is consumed in the diet, or the body cannot remove this by-product fast enough, uric acid can build up in the blood. The high uric acid can lead to gout, a painful joint caused by a buildup of uric acid crystals in the joints. Hence, purine has been removed from nattokinase NSK-SD® and it is safe for users with high uric acid or gout issues.

High stability

Nattokinase NSK-SD® is stable for 42 months at room temperature and 18 months at 40 oC. Hence, no refrigeration is required.

Nattokinase NSK-SD® is highly stable

High bioavailability

Nattokinase level significantly increases in blood from 2 hours after intake with peak concentration at 13.3 hours. NSK-SD® starts dissolve harmful clots in blood vessels on the day of intake

Established standardized and quality levels for all nattokinase

NSK-SD® is standardised to a nattokinase enzyme activity of 20,000 fibrin degradation units (FU)/g
