Hello,
Vitamin D3 is a specific form of vitamin D. While there are several forms of vitamin D, including D1, D2, and D3, vitamin D3 (cholecalciferol) is the one most commonly associated with human health. It's the form produced in the skin in response to sunlight exposure and is also available in dietary supplements.
In summary, vitamin D3 is a type of vitamin D, and when people refer to "vitamin D," they usually mean vitamin D3 because it is the most important for overall health.
