Vitamin D is a steroid vitamin, a group of fat-soluble pro-hormones that are best known for the role they play in supporting bone health and aiding in the absorption of calcium and phosphate from the gastrointestinal tract. However, a growing body of research highlights its important role in supporting other body systems, including cardiovascular and blood sugar balance as well as increasing musculoskeletal strength, neurological and immune function enabled by its ability to target over 200 different genes throughout the body. At the same time, deficiency and insufficiency of this important nutrient has reached epidemic proportions around the world, making the achievement of optimal levels extremely important to overall health.
Known as the sunshine vitamin, one of the key roles of vitamin D is maintaining serum calcium and phosphorous balance. The body makes vitamin D by converting vitamin D2 to D3, or cholecalciferol, when exposed to sunlight. Vitamin D3 is also the form which the body derives from dietary cholesterol. While vitamin D is available in both forms as supplements, studies have found vitamin D3 is the preferable form, as it has been found to maintain active vitamin D levels for a longer period of time.
The Vitamin D formula is delivered as D3 (cholecalciferol) for optimal use by the body.

Vitamin D is most widely known as the sunshine vitamin because the body is able to 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 D is available in two different forms, D2 and D3. Vitamin D3 is the preferable form as it has been found to maintain vitamin D levels in the body for a longer period of time when compared to vitamin D2.
Vitamin D Depletion
While it has long been assumed that the majority of the population achieves adequate levels of vitamin D through exposure to the sun, the biosynthesis of the nutrient is affected by time of day, seasons, location, smog/pollution, clothing, and sunscreen.
Bone and Dental Health
Numerous studies have highlighted the importance of vitamin D to maintaining healthy bone density.
Cardiovascular Health and Blood Sugar Balance
In light of the role that vitamin D plays in a variety of tissues and body systems, it comes as no surprise that much research from recent years has underscored its contribution to cardiometabolic wellness. Vitamin D has also been shown to support healthy blood sugar metabolism.
Immune Health and Modulation
One of the more profound functions of vitamin D is its ability to modulate immunity. An important recent study suggested that improving vitamin D status significantly affects the expression of genetic pathways linked to immune activity. Vitamin D has been shown to boost the immune response by up-regulating specific genes.
Numerous studies also point to the key role of vitamin D in supporting musculoskeletal strength and comfort.
