There are two types of Vitamin D. Vitamin D3 (cholecalciferol) is produced by the skin through absorbing sunlight. Vitamin D2 (ergocalciferol) is produced from plants and mushrooms. Vitamin D3 is 87 per cent more effective in raising Vitamin D levels*. The sun’s rays provide ultraviolet B (UVB) energy. The sun-skin contact kicks off the process of producing pre-vitamin D and then in the liver and kidney to start making vitamin D.
