Sunlight and Vitamin D Synthesis. Exposure to the sunâs ultraviolet (UV) rays is required for vitamin D3 (cholecalciferol) to be produced. Vitamin D3 is synthesized in the skin once your unprotected skin receives exposure to sunlights UV rays. The sun emits three different types of radiation, UVA, UVB and UVC.

Excess B and C vitamins are excreted in the urine. Vitamins are organic substances that are required by the body and must be consumed in the diet. The human body does not have the ability to synthesize vitamins, and a lack of dietary intake of vitamins can lead to deficiency. The body has an efficient system to absorb, metabolize, store and excrete vitamins so that it gets what it needs to function and it eliminates the excess. Vitamins B and C are water soluble and any surplus of these vitamins is excreted in the urine.
