Is Cholecalciferol Gluten Free?

Cholecalciferol, commonly referred to as Vitamin D3, is a fat-soluble vitamin that plays a crucial role in maintaining bone health by aiding calcium absorption. It is naturally synthesized in the skin upon exposure to sunlight, but it can also be obtained through dietary supplements and fortified foods. Traditionally, cholecalciferol is sourced from lanolin, a substance derived from sheep's wool, or from fish oil. However, vegan-friendly versions of Vitamin D3 are available, which are synthesized from algae or lichen.
