@midas007: I kept seeing D3 + K2 together and finally wanted to know WHY. 😂 The easiest way I remember it: D3 lets calcium in. K2 helps direct traffic. Different jobs, which is why you’ll often see them paired together. Turns out the extra letter on the bottle wasn’t just there for decoration. 😂 #MicroIngredients #VitaminD3 #VitaminK2 #D3K2 #SupplementEducation
