Vitamin A is a fat-soluble vitamin that is naturally present in many foods. Vitamin is essential for healthy reproduction, immune function, growth and development, and vision. Vitamin helps your heart, lungs, and other organs to function properly. For example, too much vitamin D can cause your levels of Vitamin to drop. A vitamin D deficiency has also been mentioned as a potential contributing factor to Vitamin toxicity. Vitamin toxicity has also been linked to birth defects, vomiting, and decreased bone density.

Preformed Vitamin (retinol and retinyl esters) and proVitamin carotenoids are the two sources of Vitamin in the human diet. Foods derived from animals, such as dairy goods, eggs, fish, and organ meats, contain preformed Vitamin. Plant pigments called proVitamin carotenoids are changed by the body into Vitamin in the intestine.

The global Vitamin A Market is estimated to surpass US$ 2,933.7 million by the end of 2027 in terms of revenue, exhibiting a CAGR of 5.9% during the forecast period (2020 to 2027).

 Beta-carotene, alpha-carotene, and beta-cryptoxanthin are the three main proVitamin carotenoids found in the human diet. Non-proVitamin carotenoids, or other carotenoids found in food like lycopene, lutein, and zeaxanthin, are those that are not converted into Vitamin  but may still have significant functions. Considering that blood samples are simple to obtain, retinol and carotenoid levels are typically assessed in plasma or serum. These levels, though, are not always accurate predictors of Vitamin status because they don't drop until the liver and other storage sites are almost completely depleted of the Vitamin nd because acute and persistent infections can lower serum and plasma retinol concentrations.

The best way to determine whether a person is getting enough Vitamin A is to measure the amount of Vitamin that is stored in their liver. Using isotope-dilution or dose-response techniques, specialised research laboratories can measure liver Vitamin reserves indirectly in clinical studies. These techniques involve monitoring plasma levels of retinol, a tracer substitute, or both over the course of several days following the administration of Vitamin
