Those supplementing with vitamin D should also be taking
vitamin K2 as vitamin D increases the need for vitamin K2.
Most are aware of vitamin K1 which is involved with blood
clotting, Newly discovered vitamin K2 is a related molecule with different
functions.

•
Is essential to building part of the myelin
sheath [2], [3]
•
