12 Unexpected Causes of Vitamin Deficiencies You Might Be Missing

9. The Seasonal Effect: How Seasons Impact Vitamin D Levels

Vitamin D, often referred to as the "sunshine vitamin," is synthesized in the skin upon exposure to sunlight. However, seasonal changes can significantly impact vitamin D levels, particularly in regions with long winters and limited sunlight. During these months, individuals may not produce enough vitamin D, leading to deficiencies that can affect bone health and immune function. To combat seasonal vitamin D deficiencies, it is important to include dietary sources of vitamin D, such as fatty fish, fortified foods, and supplements, especially during the winter months. Regular monitoring of vitamin D levels can also help identify deficiencies early and guide supplementation needs. By understanding the seasonal impact on vitamin D status, individuals can take proactive steps to maintain adequate levels year-round.
