Did you know that a combination of vitamins D3 and K2 can bring great health benefits to your bones and heart?

Much research has been published into the health benefits of vitamin D, but now new research is demonstrating that vitamin D3 combined with vitamin K2 can pack a powerful health punch. This potent combination is particularly effective for bone strength and cardiovascular health. Let’s take a look at these vitamins in more detail.


Vitamin D is essential for a wide variety of functions, including helping to regulate the amount of calcium and phosphate in the body. These substances are needed for healthy bones and teeth.

Vitamin D  may have other important roles in the body including regulating cell growth, neuromuscular and immune function and reducing inflammation. Vitamin D is found in a small number of foods such as oily fish, eggs and fortified breakfast cereals but the best form is through exposing the skin to sunlight. Vitamin D from sunlight acts as a pro-hormone, rapidly converting to vitamin D3.


Rather than being a single nutrient, vitamin K is actually the name given to a group of vitamins of similar composition. The two main groups of vitamin K that occur naturally are vitamin K1 (phylloquinone) and K2 (menaquinone). K1 is found in many green vegetables and K2 is produced by bacteria. Vitamin K2 is an important fat-soluble vitamin that plays critical roles in protecting the heart and brain and building strong bones. Its role in the body is to help move calcium into the right areas, such as the bones and teeth. It also helps remove calcium from areas where it shouldn’t be such as in the arteries and soft tissues. A large part of arterial plaque consists of calcium deposits
(atherosclerosis), hence the term ‘hardening of the arteries.’


Supplementing with vitamin D greatly enhances the body’s ability to absorb calcium. However, vitamin K2 is necessary to move the calcium where it is supposed to be in the body. Vitamin K2 activates a protein hormone called  osteocalcin, produced by osteoblasts, which helps to bind calcium into the matrix of the bone. Osteocalcin also appears to help prevent calcium from depositing into the arteries. Thus, without vitamin K2, the calcium brought into the body by vitamin D may begin to build up in the arteries rather than in the bones. Vitamin K and vitamin D work together to increase Matrix GLA Protein (or MGP), the protein which protects the blood vessels from calcification.
