[0002] Vitamin A, also known as retinol, is one of the nutrients necessary for the human body. Vitamin A only exists in animal foods, such as the liver of mammals and fish, and has not yet been found in plant tissues. Since 1913, when American chemist Davis extracted Chemicalbook from cod liver, the physiological functions of vitamin A have been continuously studied and discovered, mainly including maintaining normal visual response, maintaining the normal morphology and function of epithelial tissue, maintaining normal bone development, strengthening immunity, and scavenging free radicals. Lack of vitamin A can lead to a variety of diseases in vision, taste, growth and development, skin, etc.
