Pure Lab - Vitamin D 1000 IU | 360 Vegi-Caps

Vitamin D helps in the development and maintenance of bones and teeth. Vitamin D (calciferol) is a fat-soluble vitamin so critical to human health that our skin manufactures it in response to sun exposure. Its role in bone health is well-documented but vitamin D receptors are also present and active in a variety of tissues outside of bones, such as in heart muscle cells and arterial muscle cells. 

This would suggest that vitamin D plays a significant role in proper cardiovascular function and blood pressure. In addition, it appears that vitamin D improves immune function by increasing the production of anti-microbial proteins that provide a natural defense against disease-causing bacteria and viruses.
