What Causes Vitamin D Deficiency? Understanding the Root Reasons
Vitamin D deficiency is increasingly common, especially among people living in urban environments. While many assume it is simply due to lack of sunlight, the reality is more complex.
Understanding the root causes of Vitamin D deficiency can help you take the right steps toward prevention and long-term health.
What causes Vitamin D deficiency?
Vitamin D deficiency is caused by limited sunlight exposure, indoor lifestyles, poor dietary intake, and inconsistent daily routines. Environmental factors like pollution and individual lifestyle habits can also reduce the body’s ability to produce adequate Vitamin D.
