What are the Risk Factors for Vitamin D Deficiency?
Several risk factors can contribute to vitamin D deficiency. These include limited exposure to sunlight, especially in higher latitudes or during winter months, having dark skin, which reduces the skinâs ability to produce vitamin D from sunlight, and certain medical conditions such as Crohn's disease or celiac disease that affect nutrient absorption. Additionally, obesity and older age are associated with lower levels of vitamin D.
