Vitamin D is a fat-soluble hormone precursor that regulates calcium absorption, immune response, and mood. Low levels are common and often go unnoticed until they show up as fatigue, low mood, or bone density changes. This test reports your 25-hydroxyvitamin D level — the most accurate marker of your body's vitamin D status.
