Serum Vitamin D

Serum vitamin D refers to the amount of vitamin D present in your blood, measured through a blood test. Vitamin D is essential for helping your body absorb calcium, which supports strong bones and teeth. It also plays a role in immune function and overall health. Factors like sunlight exposure, diet, and supplements influence your vitamin D levels. Maintaining adequate serum vitamin D helps prevent bone disorders such as rickets and osteoporosis, and may support immune and mental health. Your healthcare provider can interpret your serum vitamin D levels to recommend appropriate intake or treatment if needed.
