Jamp Vitamin D Side Effects
What is vitamin D-oral, and how does it work (mechanism of action)?
Vitamin D is a necessary vitamin for the growth and development of bones. Vitamin D is commonly known as ergocalciferol (Vitamin D2) and cholecalciferol (Vitamin D3). Vitamin D2 and D3 are broken down to their active form, calcitriol, in the body. Calcitriol works by increasing absorption of calcium and phosphorus in the body. Calcitriol also prevents loss of calcium and phosphorus from kidneys so they are absorbed back in the body to maintain sufficient levels.
