Vitamin D is known as the sunshine vitamin because the body can make vitamin D when exposed to sunlight. Vitamin D plays an important role in supporting bone health, maintaining cardiovascular function and immune function, and promoting an overall sense of well-being.  

Vitamin  K2 is a group of related compounds differentiated by their side chains. Vitamin K2 as MK-7 is the more bioavailable form of the nutrient 7 and more powerfully influences bone building than K1. The combination of Vitamin K2 with Vitamin D3 has been suggested in recent studies to promote bone health.
