Yes, vitamin D3 (cholecalciferol) is often sourced from lanolin, which is a type of wax found in sheep's wool. Lanolin is extracted from the wool after it's shorn from the sheep. Through exposure to UV light, chemical changes occur within the lanolin, producing vitamin D3. This form of vitamin D is widely used in dietary supplements and certain food products to enhance vitamin D content. It's a popular choice for vitamin D supplementation because it's identical to the form of vitamin D produced by our bodies when exposed to sunlight.
