Vitamin D is a fat-soluble vitamin that plays a crucial role in maintaining overall health and well-being. It exists in two main forms: vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Vitamin D3 is synthesized in the skin upon exposure to sunlight, while vitamin D2 is obtained from dietary sources or supplements.

Natural sources of vitamin D include sunlight exposure, fatty fish (such as salmon and mackerel), egg yolks, fortified dairy products, and fortified cereals. However, obtaining sufficient vitamin D solely through sunlight and dietary sources can be challenging, especially for individuals with limited sun exposure or dietary restrictions. In such cases, vitamin D supplements may be recommended to meet the recommended daily intake.

Vitamin D has several critical functions in the body, including calcium and phosphorus absorption, bone and muscle health, immune support, and cell growth.

Ellement includes Vitamin D3 (Cholecalciferol) which is generally considered more beneficial than Vitamin D2 (ergocalciferol) due to its better absorption, longer half-life, and more efficient conversion into the active form of vitamin D.

Vitamin D3 is more effectively absorbed and utilized by the body, raises blood levels of vitamin D more effectively, and remains in the body for a longer period. Research suggests that vitamin D3 supplementation is more effective at maintaining adequate vitamin D levels and supporting bone health compared to vitamin D2.
