Hi,

It is not safe to take vitamin K2 supplements while on warfarin. Vitamin K2 supplements and other forms of vitamin K can interfere with blood-thinning medications like warfarin by reducing their anticlotting effects hence it is not advisable to take them together.

Hope I have answered your query. Let me know if I can assist you further.

Take care

Regards,
