  • As a Vitamin, it facilitates calcium absorption. It is vital for bone and dental health.
  • It prevents osteoporosis and other bone-related diseases such as rheumatic joint inflammation.
  • It is converted into a hormone by the human body. This vitamin is derived from 7-dehydrocholesterol but converted to 1.25 D3 dihydroxyvitamin, or calcitriol, by the kidneys and liver.
  • Calcitriol plays a role in controlling the level of phosphorus, calcium, and bone metabolism.

In the liver and kidneys, this “vitamin” is then further converted step by step into the sufficient steroid hormone 1,25 Dihydxoxycholcalciferol.

Especially in people of advanced age, the ability to produce vitamin D3 unfortunately diminishes. But also in people who are mainly in rooms or for other reasons too seldom come into contact with sunlight (for example night workers or veiled women) the vitamin production is often much too low.
