Hi everyone. Ive been looking for a vitamin K supplement. I have previously purchased and taken two different ones, which stated they were K2 derived from natto (seaweed)but I reacted very badly to this. So I'm guessing I may benefit from a synthetic type instead. I would just like to know what is the synthetic Vitamin K, is it MK4? Ive been looking into the different vitamin K types but I dont really understand it all. The only thing I am aware of is that I cannot tolerate Vitamin K2 derived from natto (which a lot of the products seem to be). Can anyone help me at all with this please?
Many Thanks
