Vitamin D

Definition

A fat-soluble vitamin that has a pivotal role in the mineralisation of bones and teeth. Vitamin D is closely associated with calcium, since it controls bone mineralisation through the regulation of calcium and phosphorus homeostasis. Additionally, vitamin D has critical physiological roles across many body functions and systems which include: cell proliferation and differentiation, regulation of the innate and adaptive immune systems, preventive effects on cardiovascular, neurodegenerative diseases, oxidative stress reduction, cognitive decline and depression, progression of skeletal and non-skeletal diseases and against risk for malignant neoplasms.
