D3 5,000 + K provides 5,000 IU per softgel of vitamin D (as D3), designed for greater absorption. This high-potency formula also includes bioavailable forms of vitamin K2 (menaquinone-7) to complement vitamin D.
In the past, vitamin D was thought to function primarily in bone mineralization. Today we know that "vitamin" D is actually a hormone that plays a role in numerous pathways and aspects of human health. Supplemental vitamin D can help.
Metagenics D3 5000 + K features 5,000 IU of vitamin D3—the most bioactive form of supplemental vitamin D.
Like vitamin D, vitamin K is an essential, fat-soluble vitamin that plays a role in bone mineralization and cardiovascular health. Unlike vitamin K1, vitamin K2 is well absorbed by the body. Vitamin K, and in particular vitamin K2, is essential for calcium utilization and bone mineralization.
Vitamin D is important for maintaining healthy bone structure and is an important nutritional factor in the proper mineralization of bones. In addition, Vitamin K is an important nutritional factor in the metabolism of bone proteins crucial to bone integrity.
Vitamin D is important for maintaining healthy immune function.
Some research suggests that vitamin D sufficiency may contribute to cardiovascular health and function. Additionally, adequate intake of menaquinone-7, or MK-7, may help contribute to healthy cardiovascular function.
