Vitamin D has several important functions. Perhaps the most vital are regulating the absorption of calcium and phosphorus and facilitating healthy immune system function....
Its anti-inflammatory, antioxidant and neuroprotective properties support immune health, muscle function and brain cell activity. Vitamin D isn't naturally found in many foods, but you can get it from fortified milk, fortified cereal, and fatty fish such as salmon, mackerel and sardines.
Vitamin D, formally known as calciferol, is a fat-soluble nutrient that has two main responsibilities: helping calcium reach your bones (which keeps them strong) and supporting your immune system so it can fight off infections. But an estimated 35% of adults have a vitamin D deficiency, and around the world, that number is much higher. Why?
According to the US Centers for Disease Control and Prevention and the National Center for Health Statistics, about one-quarter of the US population is at risk of not having enough vitamin D. Low levels of vitamin D have been linked to fatigue, aches and muscle weakness, among other problems.

Vitamin D's best-known role is to keep bones healthy by increasing the intestinal absorption of calcium. Without enough vitamin D, the body can only absorb 10% to 15% of dietary calcium, but 30% to 40% absorption is the rule when vitamin reserves are normal. A lack of vitamin D in children causes rickets; in adults, it causes osteomalacia.
Vitamin D is essential for immune system function and bone health. It may also influence mood regulation and reduce the risk of several chronic health conditions, but more research is needed to better understand vitamin D benefits.
Indeed, a growing body of evidence shows that vitamin D is important for preventing and treating numerous conditions, including asthma, heart failure, and autoimmune diseases such as multiple sclerosis and inflammatory bowel disease (e.g., Crohn’s disease, ulcerative colitis). [3][4][5] How Do We Get Vitamin D?
Responsible for increasing intestinal absorption of calcium, magnesium and phosphate, Vitamin D plays a vital role in your overall health. It’s essential for bone density, building your immune system and regulating cell growth, among other key biologic functions.
Vitamin D is pivotal for more than just bone health; it influences our immune system, mood, and overall well-being. We will take a deep dive into what it is, the benefits of maintaining sufficient levels, underscoring the importance of vitamin D in our daily health regimen.
