1,25-Dihydroxyvitamin D

1,25-Dihydroxyvitamin D, also known as calcitriol, is the active form of vitamin D in the body. It is crucial for maintaining healthy bones by helping the body absorb calcium and phosphate from food. Our skin produces vitamin D when exposed to sunlight, which is then converted into its active form in the liver and kidneys. This substance also plays a role in supporting the immune system and regulating cell growth. Adequate levels are important for overall health, and deficiencies can lead to issues like weakened bones and increased risk of certain diseases.
