active vitamin D

Active vitamin D, often referred to as calcitriol, is the form of vitamin D our body uses to regulate important functions, especially calcium and phosphate levels. It is vital for maintaining healthy bones and teeth, supporting immune function, and even influencing mood. Our skin produces vitamin D when exposed to sunlight, but it must be converted in the liver and kidneys to become active. A deficiency can lead to bone disorders like rickets in children or osteomalacia in adults, highlighting the importance of adequate vitamin D from sunlight, diet, or supplements for overall health.
