What it is

Your stored vitamin D, measured as 25-hydroxyvitamin D.

Why it matters

It supports calcium handling and bone, and low levels are very common in anyone who spends winters away from strong sun.

Reading the number

Around 30 ng/mL is the usual sufficiency mark, though labs disagree about it. Expect a real seasonal swing, so compare like months.
