Vitamin D is a nutrient that is essential for many bodily functions, including bone health, immune function, and mood regulation. Vitamin D deficiency is a common problem, especially in people who live in northern latitudes or who don’t get enough exposure to sunlight. There are a number of ways to boost your vitamin D levels, including:
Sunlight exposure: The best way to get vitamin D is through exposure to sunlight. The sun’s ultraviolet B (UVB) rays trigger the production of vitamin D in the skin. Aim for 10-15 minutes of unprotected sun exposure on your face, arms, and legs most days of the week.
