Vitamin D deficiency and health impacts

Overview

Vitamin D is essential for calcium and phosphate metabolism, supporting bone strength, muscle function, and the immune system. While the body synthesizes the vitamin through UVB radiation from sunlight, dietary sources are often insufficient to meet daily requirements.

Deficiency can lead to serious health complications, such as muscle weakness, bone pain, osteomalacia in adults, and rickets in children. Risk factors include limited mobility, low sunlight exposure, darker skin pigmentation, and certain chronic conditions affecting the liver, kidneys, or gastrointestinal tract. Certain medications may also impact vitamin levels.

In regions like Germany, natural synthesis is typically only possible from March to October, leaving the body to rely on stored reserves during winter. Because both deficiency and excessive supplementation can cause health issues, medical professionals recommend blood tests to measure 25-hydroxyvitamin D levels before beginning a supplementation regimen.
