Recently i found out that real soy sauce (not the one that’s usually found at supermarkets) is made through a process of fermentation.
So i wanted to know how much K2 is in fermented soy sauce. Since natto is one of the best sources of K2, i assumed fermented soy sauce must be rich in it as well, but i can’t seem to find that information anywhere.
Thanks.
Fermented soy sauce is typically used as a condiment in small amounts, so it’s not a significant source of vitamin K2 in the diet. To get more vit K2 eat foods like cheese, eggs, and certain fermented foods like natto.
WebMD claims natto has 150 micrograms of K2, eel is also high with 63 microgms for every 100 gms. Otherwise good cheeses (ie, not fake cheddar), organ meats especially liver, and egg yolks (if the chickens have good diets).
You don’t need much of K2, its not like Vit C or D2 or other minerals.
