Vitamin D Supplementation

Meaning

Vitamin D Supplementation is the deliberate clinical practice of orally administering cholecalciferol (D3) or ergocalciferol (D2) to effectively raise and maintain serum levels of 25-hydroxyvitamin D within the optimal physiological range. This essential intervention is crucial for supporting robust bone health, optimal immune function, and numerous endocrine processes, as Vitamin D functions as a secosteroid hormone. Correcting documented deficiency through supplementation is a foundational and non-negotiable element of preventive and hormonal wellness care.
