Vitamin D Ultra 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 other Vitamin D supplements 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.
Directions: One capsule a day with meal.
I've not had any testing yet to see whether my level of Vitamin D has risen or not. But it doesn't bother my stomach: so far so good.
