Description

Nattokinase is an all-natural, potent enzyme that is extracted from natto and highly purified. Natto is a fermented soybean food that has been consumed in Japan for over 1000 years. Nattokinase has been the subject of many studies, including human and animal trials. In 1980, researchers discovered that nattokinase demonstrated a positive effect on blood flow in vitro. Nattokinase may also support cardiovascular health.

Key Ingredients

Natto is a fermented, cheese-like food that is popular in Japan, where it has been consumed safely for more than 1000 years. It is made through the fermentation of boiled soybeans by the bacterium Bacillus subtilis natto. In 1980, during a series of in vitro experiments at the University of Chicago Medical School, Dr. Hiroyuki Sumi discovered that natto could affect fibrin levels. Fibrin is a whitish, filamentous protein that is formed in blood after a trauma or injury to protect the body from excessive blood loss. Strands of fibrin can accumulate along the walls of blood vessels and affect blood flow. After Dr. Sumi discovered the effect of natto on fibrin, he proceeded to look for natto’s active component. He then isolated and named this component “nattokinase,” which means “enzyme in natto.” According to Dr. Sumi, a 150-g portion of natto contains approximately 500 mg of nattokinase.[1] Nattokinase is produced by Bacillus subtilis natto during the soybean fermentation process. While other soy foods contain enzymes, only the natto preparation contains the nattokinase enzyme. Nattokinase is not a kinase enzyme but a serine protease enzyme.

How Nattokinase Works

Nattokinase supports healthy levels of fibrin and supports healthy blood flow through protease enzyme action (eg, subtilisin protease, bacillopeptidase F).[2,3] Not only does nattokinase act directly on fibrin, but as demonstrated by in vitro work, its action also causes the release of substances that trigger the body’s production of other important enzymes that help regulate fibrin formation. Nattokinase can also inhibit a key enzyme that affects extracellular and arterial vasoconstriction,
and it can generate tissue plasminogen activators.[4,5] Other in vitro work revealed that nattokinase caused a significant, dose-dependent decrease in red blood cell aggregation and low-shear viscosity, and these beneficial effects were evident at concentrations similar to those achieved with in vivo animal trials.[6] The Japanese have long believed that natto supports
healthy blood flow. Now, as outlined above, modern science has uncovered mechanisms underlying this belief.*[2-8]

Animal and Human Studies

In preliminary research performed by Dr. Sumi and his colleague Masugi Maruyama, an extract of natto (equivalent to 25mg and 200 mg, respectively) showed a healthy influence on blood pressure in Wistar rats and in humans.[9] In another animal study performed on dogs, nattokinase was tested against a placebo. Oral administration (1-g nattokinase in 4 capsules containing 250 mg each) supported normal circulation, as shown by the angiogram.[2] More recently, to examine
the effects of nattokinase supplementation on blood pressure in humans, 86 people aged 20 to 80 years participated in an 8-week, randomized, double-blind, placebo-controlled trial. Seventy-three subjects completed the protocol. The researchers found that oral nattokinase supplementation (2000 FU/capsule) resulted in a healthy effect on blood flow. [10] Purety Family Medical Clinic ’s Nattokinase provides 1000 FU/capsule with a recommended dosage of 2 capsules per
day. It is important to note that both natto and nattokinase have been demonstrated to have activity in humans, whereas supplementing with boiled soybeans did not.[2] Animal research has demonstrated that nattokinase escapes the action of digestive enzymes and is absorbed from the small intestine to perform in plasma.*[11,12]

Suggested Dosage

Take one to two capsules twice daily at least 30 minutes before or two hours after a meal, or as directed by your healthcare professional. Consult your healthcare professional prior to use.Individuals taking medication should discuss potential interactions with their healthcare professional. Do not use if tamper seal is damaged.

Restrictions to use

Consult your healthcare professional before taking this product if you have a bleeding disorder or are taking any drug that affects blood coagulation or blood pressure, such as heparin, warfarin (Coumadin), diuretics, ACE inhibitors, or beta-blockers.

They are high-quality and worth the money. The store also offered free shipping at that price so that's a plus!” “I recently purchased the Anti Aging Gel and serum from puretyclinic, and I couldn't be happier with my online shopping experience. Their website was user-friendly, making it easy to find the perfect item.
