For vitamin D3 supply - usefully combined with vitamin K2 What makes proSanVitamin D3+K2 (MK-7) special is the combination with vitamin K2. The vitamin K2 (MK-7) used in proSanVitamin D3+K2 (MK-7) comes from natural plant sources – it is well absorbed by the body and remains active longer than other forms of K2. In combination with vitamin D3, this long-acting form of K2 therefore ensures an adequate supply to all organs and tissues. Both vitamin D and vitamin K are fat-soluble vitamins. Therefore, both require fat/oil as a transport medium – only then can the body utilize and absorb vitamins D3 and K2. proSanVitamin D3+K2 (MK-7) capsules contain liquid D3 and K2 with very high bioavailability in an oil base. Application: Unless otherwise advised by your doctor, take 1 capsule daily without chewing it with some liquid, either with or after a meal.
