It differs from other vitamins in that the human body can synthesize it from sun exposure. However, due to modern lifestyles, the use of sunscreens, and less sun exposure during winter, many people do not reach optimal levels. Supplementation with vitamin D3 has become a common practice to maintain adequate levels throughout the year.\u003c\/p\u003e\u003cp\u003eThere are two main forms of vitamin D: D2 (ergocalciferol) of plant origin and D3 (cholecalciferol), which is the identical form to that produced by the skin when exposed to the sun. Vitamin D3 is the most recommended due to its greater effectiveness in raising and maintaining blood levels of vitamin D.\u003c\/p\u003e\u003ch2\u003eHealth benefits of vitamin D\u003c\/h2\u003e\u003cp\u003eAccording to the European Food Safety Authority (EFSA), vitamin D contributes to:\u003c\/p\u003e\u003cul\u003e\n\n\u003cli\u003eThe normal absorption and utilization of calcium and phosphorus.\u003c\/li\u003e\n\n\u003cli\u003eThe maintenance of normal blood calcium levels.\u003c\/li\u003e\n\n\u003cli\u003eThe maintenance of normal bones.\u003c\/li\u003e\n\n\u003cli\u003eThe normal functioning of muscles.\u003c\/li\u003e\n\n\u003cli\u003eThe normal functioning of the immune system.\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\u003cp\u003eIn addition, vitamin D contributes to the process of cell division.

Vitamin D3 (cholecalciferol) is of animal origin, usually sheep lanolin, and is the same molecule that human skin produces.\u003c\/p\u003e\u003cp\u003eNumerous studies indicate that vitamin D3 is more effective than D2 in raising and maintaining serum levels of 25-hydroxyvitamin D. Therefore, most high-quality supplements use D3 as the active form.
