Understanding 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.1,2 Supplemental vitamin D can help.

Why vitamin D with K

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.3-5 Vitamin K, and in particular vitamin K2, is essential for calcium utilization and bone mineralization.*

Healthy bones

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.*

Immune system support

Vitamin D is important for maintaining healthy immune function.*


Healthy cardiovascular 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.*3,4
