What it is

Vitamin D3, also known as cholecalciferol, is a fat-soluble vitamin that helps the body absorb calcium. It is naturally produced in the skin when exposed to sunlight. It can also be obtained from certain animal-based foods or added to fortified foods.

Why it's used

Manufacturers add Vitamin D3 to foods to increase their nutritional value, as many people do not get enough from sunlight or diet alone. It is commonly found in dairy products like milk, fortified cereals, orange juice, and some plant-based milk alternatives.

Health notes

Vitamin D3 is considered essential for bone health and immune function. The FDA lists Vitamin D3 as Generally Recognized As Safe (GRAS) when used as a nutrient. The World Health Organization (WHO) and the European Food Safety Authority (EFSA) have also evaluated Vitamin D and its derivatives. Adequate intake is important, but excessive amounts can lead to health issues.

Allergen info

Vitamin D3 itself is not one of the 9 major allergens. However, it is often added to dairy products, which are a major allergen.
