What it is
Retinol is a form of vitamin A, an essential nutrient for vision, immune function, and cell growth. It is found naturally in animal products like liver, fish oil, and dairy. It can also be synthesized for use in supplements and fortified foods.
Why it's used
Retinol is primarily added to foods as a nutrient to fortify them with vitamin A. It is commonly found in fortified dairy products, cereals, and infant formulas to help consumers meet their daily vitamin A requirements.
Health notes
Retinol is recognized as safe and effective by the FDA when used as a nutrient. Excessive intake of preformed vitamin A (retinol) can lead to toxicity, with symptoms including dizziness, nausea, and headaches. The WHO and EFSA have evaluated vitamin A and established recommended daily intake levels. Research is ongoing regarding the long-term effects of high-dose vitamin A supplementation.
Allergen info
Retinol itself is not a major allergen. However, it can be derived from animal sources, which may be a concern for some dietary restrictions.
