| name | Vitamin D |
| Classification | Fat-soluble vitamin |
| Pharmacokinetics | Vitamin D is absorbed in the small intestine with the help of dietary fat. It is then transported to the liver, where it is hydroxylated, and further hydroxylated in the kidneys to its active form, calcitriol. The active form is primarily responsible for calcium and phosphorus homeostasis and bone health. Vitamin D is stored in the liver and adipose tissue. |
