The vitamin that is converted by sunlight on the skin and found in fortified food products is vitamin D.
To understand how this conversion process occurs, we need to delve into the details. When your skin is exposed to ultraviolet B (UVB) radiation from sunlight, a precursor molecule called 7-dehydrocholesterol, which is present in your skin, undergoes a chemical reaction. This reaction converts 7-dehydrocholesterol into vitamin D3, also known as cholecalciferol.
Vitamin D can also be obtained through dietary sources. Certain food products, such as milk, cereal, and orange juice, are often fortified with vitamin D. This means that the vitamin is added to these products during the manufacturing process to increase their nutritional value.
So, to recap, when sunlight interacts with your skin, it triggers the conversion of 7-dehydrocholesterol into vitamin D3, and fortified food products are those that have had vitamin D added to them.
