Vitamin D3 + K2

Vitamin D3 + K2 - The Vitamin D3 level is 25 mcg / 1000 IU; equivalent to 500% daily recommended amount - The Vitamin K2 level is 37.5 mcg; equivalent to 42% daily recommended amount However, most of our vitamin D is produced by our body itself. This happens when ultraviolet (UV) rays from the sun hit your skin. As a result, vitamin D3 (cholecalciferol) is formed in the skin and stored as an inactive substance in the fatty tissue of our body. In the Netherlands, the sun is only bright enough for five months a year to provide the skin with its radiation needs. D3 supplementation therefore seems to be a necessity rather than a luxury for every Dutch person, especially in the months that are somewhat darker. Vitamin K2 is important for the absorption of D3 --- Vitamin D3 has a positive effect on the immune system Vitamin D3 is good for the muscles Vitamin D3 and K2 contribute to the maintenance of strong bones
