Vitamin D is essential for calcium absorption, bone health, immune function, and cardiovascular health. Despite its name, Vitamin D acts more like a hormone than a vitamin. Deficiency is remarkably common, affecting an estimated 40% of US adults. Levels below 20 ng/mL are deficient, 20-30 ng/mL is insufficient, and above 30 ng/mL is sufficient. Most experts now recommend aiming for at least 30 ng/mL.
