The body can produce its own vitamin D3 when exposed to sunlight, with various studies suggesting that a small amount of daily or bi-weekly exposure can be sufficient for most individuals. The critical question of how long to stay in sun for vitamin D3 depends on several factors, including your skin tone, location, and the time of day.

An estimated 50% of the global population is at risk for vitamin D insufficiency or deficiency, despite the availability of sunlight. Our bodies produce this essential nutrient when skin is exposed to a specific type of sunlight, though many factors can influence its production.
