A review of the many mechanisms by which vitamin D maintains overall good health and reduces the risk of multiple adverse health outcomes.

Key Points

  • In addition to its role in bone health, vitamin D supports immune function, helps regulate cell growth and differentiation, and plays a role in reducing inflammation; adequate vitamin D levels have been associated with a lower risk of various chronic diseases, including certain cancers, cardiovascular disease, dementia and cognitive decline, respiratory infections, diabetes, autoimmune disorders, and many others
  • A review by Grant et al. listed several mechanisms by which vitamin D is capable of affecting such a wide variety of health outcomes beyond bone health, including autoimmune diseases, cancer, cardiovascular disease, infectious diseases, inflammation, insulin resistance, muscle health, and pregnancy outcomes
  • Vitamin D deficiency affects every part of the body; use our interactive PDF to learn more

The needs and actions of vitamin D go well beyond bone health.  Unfortunately, there are still times that we run across an article or response that claims that vitamin D is only necessary for bone health, while discounting its many other health effects.

Research over the past several decades has shown that vitamin D is important to many biological pathways in the body. In addition to its role in bone health, vitamin D supports immune function, helps regulate cell growth and differentiation, and plays a role in reducing inflammation. Adequate vitamin D levels have been associated with a lower risk of various chronic diseases, including certain cancers, cardiovascular disease, dementia and cognitive decline, respiratory infections, diabetes, autoimmune disorders, and many others.

A recent paper by Grant et al. reviewed the shared risk factors between periodontal disease and other systemic, chronic diseases and adverse health conditions. The paper concluded that low vitamin D status was a strong risk factor for each of these adverse health outcomes, and also the easiest to address.

How Can Vitamin D Affect Our Health in so Many Different Ways?

Included in this review was a list describing the mechanisms by which vitamin D is capable of affecting such a wide variety of health outcomes beyond bone health, including autoimmune diseases, cancer, cardiovascular disease, infectious diseases, inflammation, insulin resistance, muscle health, and pregnancy outcomes.

Vitamin D Affects Every Part of the Body

The list above is only a sample of the wide variety of actions that vitamin D has within the body.

Vitamin D is needed by virtually every cell in the body and is essential for hundreds of processes each and every day. It acts as a protector and regulator of all cell types, tissues, and organs, it can enhance the functioning of each system of the body to help keep us healthy.  A deficit in vitamin D can lead to impairment or disease in each of these systems – from brittle bones to heart disease, cancer, and dementia.
