The 25-Hydroxy Vitamin D test is the most accurate way to measure vitamin D status. Vitamin D is essential for bone health, immune function, mood regulation, and muscle strength. An estimated 42% of American adults are deficient, with higher rates among those with darker skin, limited sun exposure, or who live in northern climates. Optimal levels are generally considered to be 30–50 ng/mL.
