There is a great deal of discussion on whether or not a person needs to take Vitamin K2 with Vitamin D3. In fact, there are many claims that K2 is necessary for the absorption of D3, which is not accurate. There really isn't a solid peer-reviewed study showing the need/benefit of taking K2 alongside D3. Most individuals get plenty of K2 in their diets and supplementation is mostly unnecessary.
We have opted to offer a high quality, absorbable Vitamin D3 on its own, allowing our customers to choose whether or not they want to add Vitamin K2.
