Is Nattokinase Same as Vitamin K2
                     Is Nattokinase Same as 
Vitamin K2?
Introduction
You may be familiar with the basic info about nattokinase, K2, and 
their connection. Vitamin K is well known for blood clotting; the less 
known Vitamin K2 is found in Nattokinase. Various nattokinase 
supplements contain vitamin K2, which is well known for its role in 
heart diseases and bone health. Natto, a Japanese cuisine made of 
fermented soybeans, is one of the richest sources of Vitamin K2.
There’s so much to share about K2, so we’ll take it one at a time. 
Read below for significant facts about vitamin K2 in 
nattokinase products and supplements.
What is Vitamin k    
 
 
There’s a lot of confusing information about Vitamin K in the atmosphere. 
However, when you see the intake recommendations, you can see that it usually 
refers to both vitamin K1 and K2 collectively.
What is Vitamin K2, and what role does it play? 
Scientists in recent decades have found that Vitamin K1 and K2 function 
differently. They have a role such as ‘on’ switches for different functions in our 
body with different targets. In the liver, vitamin K1 activates the protein in the 
body that helps with blood coagulation. For example, when you get a cut or 
wound on the skin, it starts bleeding for a short time and eventually stops. This is 
due to the presence of Vitamin K1 in the body that turns on the process that 
thickens the blood at the wound, which stops flowing. Without Vitamin K1 
activating these proteins, the blood would be unable to stop and eventually clot.
Vitamin K2 plays the process outside the liver, like in bones or blood vessels of the 
body. Vitamin K2 activates the protein called Matrix-Gla Protein (MGP) in the 
blood vessels, which removes calcium from the lining of blood vessels. Vitamin K2 
is also essential for heart health as clarification of blood vessels can be a risk 
factor for heart diseases. In bones, vitamin K2 activates a bone-forming protein 
called osteocalcin, which is essential for bone health. It helps our bones to draw 
calcium from blood vessels in the body and turn it into bone tissue. You can get 
various customized nattokinase products rich in Vitamin K2.
Nattokinase and Vitamin K2 for bones 
        
Nattokinase is one of the rare plant sources of Vitamin 
K2, which plays an essential role in the bone health of 
our body. It is said that calcium, vitamin D, and vitamin 
K2 act together for bone health. A 100gm portion of 
natto contributes to 22% of the daily calcium intake. 
Calcium is the basic building block of bone tissue. 
While we eat anything, it goes through the digestive 
tract in our body and is absorbed in our small intestine. 
Calcium is also required for other body functions, and if 
we don’t get it from the food we eat, our body pulls it 
from the storage, i.e. Our bones. This is why a 
deficiency in calcium in our diet can lead to conditions 
like osteoporosis, a bone disease that occurs when the 
bones get weak.
Calcium may be difficult for our bodies to utilize and 
absorb, which is where vitamin D plays the role. It 
improves our body’s ability to absorb calcium from our 
diet more efficiently. Vitamin D signals the body that 
calcium is available from a food source and prevents 
our body from taking calcium from our bones when we 
get enough from our diet. The next step involves the 
role of vitamin K2. Once you’ve absorbed the calcium 
with the help of vitamin D, vitamin K2 helps our bones 
to draw this calcium out of the bloodstream and deposit 
it in the bone tissue.
Nattokinase and Vitamin K2 for heart health 
Vitamin K2 plays a role in improving heart health 
as well. Nattokinase supplements like 
BSNK66 nattokinase help to dissolve blood clots 
and maintain optimal blood flow, lowering heart 
diseases and improving heart health.
        
In the development of atherosclerosis (a disease 
in which plaque builds inside your arteries), the 
plaques can break and form a blockage in your 
blood vessels. A blockage in an artery that 
supplies blood to the heart may lead to a heart 
attack. These plaques are partially made of 
calcium, so calcium deposits in arteries can be a 
risk factor for heart attack and other heart 
problems.
Vitamin K2 helps to activate a protein in the body 
that removes calcium from blood vessels. Higher 
vitamin K2 intake is directly linked to decreased 
heart diseases. You may not be aware of the 
interconnected roles of Vitamin K2, Calcium, and 
Vitamin D, so you focus on more calcium intake. 
Still, the fact is that more calcium intake can lead 
to heart diseases.
Sources of Vitamin K2
Natto, a Japanese cuisine made from fermented soya beans, contains 
significantly more vitamin K2 than any other food source. Other than that, the 
sources of vitamin K2 include animal foods, meat, egg, and high-fat dairy 
products. Many animals can convert vitamin K1 into K2, which is why animal 
food is said to be a good source of vitamin K2.
 
How much Vitamin K2 intake is enough for our body? 
There are no such formal intake recommendations for vitamin K2. The average 
intake of vitamin K2 is 28.5 micrograms per day, and it is believed that those 
who intake more may be healthier.
Although there is not much about Vitamin K2 in the food and beverage industry, 
it has shown rapid growth over the last 5-10 years in the supplements industry. 
Adding vitamin K2 to different plant-based sources can at least try to fill this 
gap.
