In dietary supplements, vitamin D3 is commonly used for its important roles in the body. It is important to follow the recommended dosage because an overdose of vitamin D can lead to various side effects. The most important natural source of vitamin D3 is sunlight, where ultraviolet B (UVB) radiation converts 7-dehydrocholesterol in the skin to vitamin D3. Vitamin D3 is also found in foods, especially fatty fish such as salmon, sardines and mackerel, eggs, liver products and to a lesser extent in some fortified foods such as dairy products and cereals. Vitamin D3 is often used as a dietary supplement, especially in areas with limited sunlight, during the fall and winter months, or in people who spend most of their time indoors.
