Vitamin D and vitamin K are both essential vitamins for regulating the density and structure of our bones. They work together to keep our immune and cardiovascular system functioning at the highest level possible.
Both vitamin D and vitamin K are excellent daily health supplements — but they each work best when taken together, rather than on their own.
Vitamin D comes in two main forms:
Vitamin D2 — ergocalciferol
Vitamin D3 — cholecalciferol
Both forms of the vitamin are important for regulating calcium metabolism, and supporting the health of the bones, immune system, and heart. However, research suggests the best form of vitamin D for supplementation is vitamin D3 — this is the same form of the vitamin naturally produced in the skin when exposed to UV light.
This important vitamin regulates calcium levels to support the formation and regeneration of bone tissue. It’s also essential for the production of lymphocytes that make up a large portion of our immune system.
Vitamin K also comes in two main forms:
Vitamin K1 — phylloquinone
Vitamin K2 — menaquinone
Vitamin K1 is most active in the liver, while K2 is active throughout the body — making it the ideal form of the supplement to support heart and bone health.
This vitamin works closely alongside vitamin D to protect the body from calcium buildup and improves the ability for vitamin D3 to maintain and build strong bones.
