Vitamin D3 (25OH)

Vitamin D3 25OH, also known as Calcidiol, plays a central role in human organism health. This biomarker is produced in the liver from the precursor vitamin D3 (Cholecalciferol) and is a reliable indicator of the vitamin D status in the bloodstream. Measuring this value is crucial as an optimal vitamin D level is essential for numerous physiological processes.

A balanced vitamin D level not only supports the regulation of calcium and phosphate metabolism, crucial for bone health, but also has extensive effects on the immune system, muscle and nerve function, and the regulation of inflammatory processes in the body. Furthermore, prolonged vitamin D deficiency can lead to serious conditions such as depression, cancer, cardiovascular diseases (e.g., heart attack, stroke), respiratory diseases (asthma), metabolic disorders (e.g., type 2 diabetes), and autoimmune diseases (e.g., multiple sclerosis).

Measuring the Vitamin D3 25OH level allows for the timely detection of potential deficiencies or excesses and the implementation of appropriate measures to optimize health. An individually tailored approach to vitamin D supplementation may be recommended based on these laboratory results to achieve an optimal vitamin D status and support long-term good health.
