Vitamin D3, also known as cholecalciferol, is a fat-soluble vitamin. This means it dissolves in fats and oils but not in water. Because of its fat solubility, it’s more effectively absorbed by the body when consumed with fats or oils.
When vitamin D3 is taken in an oil form, such as in softgel capsules or liquid drops, it enhances its absorption because it mimics the natural environment of the vitamin in the body. The oil acts as a carrier, helping the body to absorb and transport the vitamin more efficiently through the digestive system.
Additionally, vitamin D3 is naturally synthesized in the skin in response to sunlight exposure, and it’s then transported in the bloodstream bound to carrier proteins, many of which are lipid-based. This further emphasizes the importance of consuming vitamin D3 with fats or oils for optimal absorption and utilization by the body.
Overall, encapsulating or dissolving vitamin D3 in oil ensures better absorption and bioavailability, making it more effective in fulfilling the body’s requirements for this essential nutrient.
