Vitamins D and K are both fat-soluble vitamins and play a central role in calcium metabolism. Vitamin D promotes the production of vitamin K-dependent proteins, which require vitamin K for carboxylation in order to function properly.

Why should you take vitamin K with vitamin D?

It's crucial that these vitamins be taken together because supplementing vitamin K with D helps the body use calcium properly to build bone instead of depositing it dangerously in arteries and soft tissue.

Why is vitamin D combined with K2?

K2 MK-7, the superior form of K2, activates the osteocalcin proteins that incorporate calcium to bones. Meanwhile, vitamin D3 aids calcium absorption into the blood and has been linked to a reduced risk of breast cancer. Kappa Bioscience reports strong growth of the synergistic combination.
