Preferred Supplements Vitamin D 5,000 IU provides a clinically useful dose of vitamin D3 and vitamin K in both the K1 and MK-7 form of K2. This formula contains higher therapeutic doses than Vitamin D 2,000 IU for situations where more aggressive repletion is required. Vitamins D and K are essential for optimal bone and arterial health and for maintaining the immune system in proper balance. The amount of vitamin D and K in this formula may be beneficial for those who do not get adequate sun exposure and/or dietary sources of these vitamins. Vitamins D & K work as a team. Thus, increasing doses of vitamin D will increase the need for vitamin K. Made with non-GMO ingredients. *These statements have not been evaluated by the Food and Drug Administration.
