Gmo-free Vitamin D3

Vitamin D3, also known as cholecalciferol, is a fat-soluble vitamin that helps the body absorb calcium and phosphorus. It is naturally produced in the skin when exposed to sunlight. In food, it is often derived from lanolin, a wool grease byproduct, or from plant-based sources like lichen.

Manufacturers add Vitamin D3 to foods to increase their nutritional value, as it is essential for bone health. It is commonly found in dairy products like milk and yogurt, as well as some cereals and orange juices. Fortification with Vitamin D helps ensure consumers meet their daily requirements.

Vitamin D3 is generally recognized as safe (GRAS) by the FDA when used as a nutrient. The National Academies of Sciences, Engineering, and Medicine have established upper intake levels for vitamin D. JECFA and EFSA have also evaluated vitamin D. Adequate intake is important for bone health and immune function. Excessive intake can lead to hypercalcemia, though this is rare from food sources alone.
