-What's the Production process of Leading's Vitamin K2?

Fermentation!

You may need to learn more regarding the difference of Vitamin K2 made by Fermentation VS chemical synthesis.

1. When you buy Vitamin K2, we would suggest you to pay attention on the assay of Cis-MK7

MK-7 has two different Isomers ,trans-MK7and cis-MK7

Trans-MK7 is exactly the active form our body need, while, the cis-MK7 is the inactive form. It means that the higher trans-MK7 and the less cis-MK-7 would be an ideal source for us. 

The content of cis-MK of Fermention is normally NOT Detect, while, it would be around 2% if made by chemical sysnthesis. 

2. We will avoid using solvent by fermentation, which would be a safer and clean option for us.
