What it is
Vitamin A and Vitamin D are essential fat-soluble vitamins. Vitamin A is important for vision, immune function, and cell growth. Vitamin D helps the body absorb calcium and phosphorus, which are crucial for bone health. They are often added to foods together as a nutrient fortification.
Why it's used
Manufacturers add Vitamin A and D to foods to increase their nutritional value, especially in products like milk, yogurt, and breakfast cereals, where they are naturally less abundant. This fortification helps consumers meet their daily recommended intake of these essential vitamins.
Health notes
In the US, Vitamin A and D are generally recognized as safe (GRAS) when used as nutrients. The National Academies of Sciences, Engineering, and Medicine have established upper intake levels for these vitamins. Both vitamins have been evaluated by international bodies like JECFA and EFSA. While generally safe, excessive intake of Vitamin A can lead to toxicity, and very high levels of Vitamin D can also cause adverse effects.
Allergen info
Not a major allergen. Vitamin A and D themselves are not derived from the major allergens. However, the food product they are added to may contain allergens.
