Source Of Vitamin A

Vitamin A is a fat-soluble vitamin essential for vision, immune function, and cell growth. It can be naturally found in foods like liver, fish oils, and dairy products. In packaged foods, it is often added in the form of retinyl palmitate or retinyl acetate, which are synthesized forms of vitamin A.

Manufacturers add vitamin A to foods to increase their nutritional value, as it is a required nutrient. It is commonly found in fortified products such as margarine, cereals, and dairy alternatives. It helps ensure consumers can meet their daily vitamin A needs through a varied diet.

Vitamin A is an essential nutrient, and the FDA permits its addition to foods. The National Academies of Sciences, Engineering, and Medicine have established upper intake levels for vitamin A. JECFA and EFSA have also evaluated vitamin A and its derivatives. Consuming excessive amounts of vitamin A from supplements or fortified foods can lead to toxicity, while deficiency can cause vision problems and impaired immunity.
