Vitamin D3 5000IU plus K1 & K2 provides a clinically useful dose of vitamin D3 along with vitamin K as both K1 and the MK-7 form of K2. This formula contains higher therapeutic doses of Vitamin D 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.
Vitamins D and K are essential for optimal bone and arterial health and for maintaining the immune system in proper balance. Vitamin K1 (the naturally occurring form of vitamin K in vegetables) and Vitamin K2 as MK-7 has the special property of metabolizing slowly throughout the day.
We now know how important Vitamin K is for directing the transport of calcium into bone and teeth for optimal strength. Increasing the amount of vitamin D, via supplementation, in the presence of inadequate levels of vitamin K, can increase the risk of calcium deposition in arteries and soft tissue and have a very negative effect on artery elasticity. This is due to their interaction in the use of MGP, Matrix Gla Protein, which is a strong inhibitor of arterial calcification. The expression of MGP is vitamin D dependent and the gamma-carboxylation step, making it active, is vitamin K dependent. Together, D and K make a great team.
CAUTION: Vitamin K may adversely interact with anticoagulation drugs known as blood thinners. Patients taking these medications should be medically supervised while taking
