Did you know that an estimated one billion people worldwide have a vitamin D deficiency? What is vitamin D and its functions is a crucial question for understanding overall health and well-being, influencing everything from bone strength to immune system performance.

Globally, more than a billion people are affected by vitamin D deficiency, a condition increasingly linked to various health issues, including anemia. Understanding what causes vitamin D anemia is essential, as the relationship between these two conditions is more complex and indirect than previously thought. It is not a direct consequence but rather a result of how vitamin D influences iron absorption and red blood cell formation.

Vitamin D, despite its name, is technically a pro-hormone that the body can produce when exposed to sunlight. As a fat-soluble vitamin, it plays a critical role in numerous physiological processes that are vital for overall health, including mineral absorption and immune response.

According to the National Institutes of Health, vitamin D deficiency is a major public health problem worldwide. Understanding the 5 major functions of vitamin D is critical for comprehending its profound impact on your overall health, from your skeletal structure to your immune response.

Approximately 1 billion people worldwide are estimated to have a vitamin D deficiency, primarily impacting bone health. While most are familiar with common dietary forms like D2 (ergocalciferol) and D3 (cholecalciferol), many are unaware of what does vitamin D5 do, a specialized analog with different origins and applications, primarily in research. This lesser-known member of the vitamin D family has been explored for therapeutic, rather than nutritional, purposes.

Over 21% of the U.S. population has insufficient vitamin D levels, according to the National Health and Nutrition Examination Survey. While many associate this vital nutrient with healthy bones, understanding what active vitamin D does reveals a more complex and far-reaching role in supporting overall physiological function.
