In the previous Health Science News Page, we discussed the benefits of vitamins D and K when applied individually. While these two fat-soluble vitamins have several health benefits, they work the best when combined.
Vitamin D by itself is important for maintaining strong bones, a healthy cardiovascular and immune system, and has anti-cancer properties. The two different types of vitamin D are D2 (ergocalciferol) present in plant-based products such as mushrooms, and D3 (cholecalciferol) present in animal products and fatty fish. It is well known that vitamin D is needed for effective absorption of calcium from the digestive system and promoting its mobilization towards the bones. It also helps in regulating the calcium-phosphorus ratio required for healthy bones. Vitamin D3 works together with vitamin K2 in maintaining calcium balance in the body affecting activation of bone protein (osteocalcin) responsible for the incorporation of calcium in the bones. In clinical trials a combination of vitamin D3 and vitamin K2, especially subtype MK-7, increased bone density in postmenopausal women with osteoporosis compared to each vitamin taken individually and a placebo.
