Vitamin D3 Added Per Quart

Vitamin D3, also known as cholecalciferol, is a fat-soluble vitamin. It is naturally produced in human skin when exposed to sunlight and found in some animal products like fatty fish and egg yolks. For food fortification, it is typically manufactured from lanolin, a wax found in sheep's wool, though plant-based sources also exist.

Manufacturers add vitamin D3 to fortify foods, especially dairy products like milk, and plant-based milk alternatives and cereals. It helps the body absorb calcium and phosphorus, which are essential for strong bones and teeth.

Vitamin D is an essential nutrient. The FDA generally recognizes vitamin D as safe (GRAS) for use in food fortification within established limits. JECFA has evaluated vitamin D and set an acceptable daily intake. EFSA has also evaluated its safety. High intakes, usually from excessive supplementation, can lead to toxicity, but this is rare from fortified foods.
