OUR VITAMIN D3 PLUS We have blended our high-quality vitamin D3 with calcium and vitamin K2 to form a multipurpose vitamin D supplement. This formula creates the optimum blend for healthy bones. Vitamin D, C, K2, calcium and magnesium contribute to the maintenance of normal bones and to the normal function of the immune system. Vitamin D3 Plus provides a high dose of vitamin D3 combined with other vitamins and minerals for the purpose of working synergistically with the body. Although calcium and vitamin D have long been considered to be key nutrients in the facilitation of bone mineral turnover, it has more recently been acknowledged that vitamin K2 is essential for this process too. When supplementing vitamin D, the body creates vitamin K2-dependant proteins (osteocalcin) that move calcium. K2 is needed to activate these proteins to move calcium into the bones. WHAT IS VITAMIN D? Vitamin D is a fat-soluable vitamin which can either be ingested in food or manufactured by the body as a result of sunlight falling on the skin. Modern lifestyles have decreased the exposure we get to the sun, which has made it more important to monitor for potential vitamin D deficiency. WHAT DOES VITAMIN D3 PLUS DO?
