NSI Nattokinase NSK-SD -- 90 Capsules

NSI Nattokinase NSK-SD -- 90 Capsules

Promotes healthy blood flow and blood pressure. An ideal, all-natural supplement to support cardiovascular health. How Does NSI® Nattokinase work? Nattokinase (NK) is an enzyme extracted from a traditional Japanese dish called natto, made from boiled and fermented soybeans. Consumed for both its taste and heart-health-promoting properties in Japan for centuries, NK was officially found to promote healthy circulation and blood pressure by Dr. Hiroyuki Sumi in the 1980s. Testing nearly 200 foods for their potential effects on blood consistency, Dr. Sumi discovered that natto was able to dissolve artificial fibrin (a protein involved in blood clotting) in a Petri dish. Since then, NK has been the subject of almost 20 animal and human studies, with results suggesting that the nutrient promotes healthy circulation and blood pressure. NK is believed to work by optimizing the blood's consistency, supporting healthy coagulation of blood and fibrinolytic activity. When combined with a healthy diet and exercise, NK may help promote cardiovascular health. NSI® Nattokinase is manufactured using NSK-SD™, a highly purified form of nattokinase manufactured with non-GMO soybeans. Unlike other nattokinase supplements, NSK-SD™ is made using a patented process that removes all vitamin K, making it safe to use for individuals taking blood-thinning medications. NSI® Nattokinase is better because it:. Delivers 100 mg of high-quality NSK-SD™ Nattokinase per one-capsule serving. Is available at a much greater value than other nattokinase products on the market. Did You Know? All NSI supplements are packaged in HDPE (High Density Polyethylene) bottles. These bottles keep moisture vapor out, protecting the freshness and integrity of their contents, and are 400% more effective compared other brands currently using PET (Polyethylene Terephthalate) bottles. HDPE bottles do not break as glass can and are also recyclable so we urge you to please recycle them.

"The NSI Natto has the high concentration of the product that I am buying and is highly effective. The cost is also what my family looks at, and the product passes that test as well. I must say that NSI products are some of the best ones I have purchased and will continue."

"I have been taking Nattokinase for only four days. My doctor said I had poor circulation in my legs and it was causing me a lot of pain. I did some research on this product and thought what the heck, I'll try this. Guess what? After four days my legs do not hurt anymore. I was able to go shopping and came home and did my usual chores and still no pain. After the first capsul I felt my legs get really warm and my feet started to tingle. That was blood flowing in my feet and legs."

"My doctor recommended this for me due to having problems with my blood coagulating too easily, and having some kind of enzyme deficiency that made me unable to respond to heparin.
Within one week of taking two of these capsules per day, I noticed my skin felt healthier and smoother - NOT kidding! My doctor said it's because the blood was able to get into small capillaries in my skin because of the ability of Nattokinase to break down the "clotting" tendency in my blood. When I stop taking it, my skin goes back to the way it was - bumpy, dry, and either too sensitive or too insensitive to light touch.
I've been taking this now for at least a year with no bad side effects.
Sarah"
