Best ways to get vitamin D
Vitamin D is produced from the cholesterol in the skin when it is exposed to the Sun. The ultraviolet B (UVB) rays from the Sun provide the energy needed for the reaction to take place in the skin. This, as a result, produces Vitamin D. You can probably get all the vitamin D you need just by going outside and sunbathing a few times per week if you live in areas where there is abundant sunlight.
