Yes, the sun can give you vitamin D. Vitamin D is known as the "sunshine vitamin" because it is produced in the skin when it is exposed to the suns ultraviolet-B (UVB) rays. During exposure to sunlight, 7-dehydrocholesterol in the skin absorbs UVB radiation and is converted to previtamin D3, which in turn isomerizes into vitamin D3. Vitamin D3 is the primary natural source of vitamin D, and it is produced in animals, including humans.
However, it is important to note that too much sun exposure can have health risks, such as skin damage and skin cancer. Additionally, many people have insufficient levels of vitamin D because they live in places where sunlight is limited in winter, or because they have limited sun exposure due to being inside much of the time. Therefore, it is recommended to get vitamin D from a variety of sources, including food and supplements. Some foods that are good sources of vitamin D include fatty fish, egg yolks, and fortified milk and cereals.
