Application

Vitamin A is mainly used to prevent night blindness, dry eye disease, and also for local suppurative infection of the skin after burns. Vitamin A in the human body should not exceed 3 mg/day for adults and 2 mg/day for children. If you take a large dose of vitamin A, because the discharge ratio is not high, acute vitamin A hyperactivity will occur. The main symptoms are short-term hydrocephalus and vomiting, and some may have symptoms such as headache, lethargy and nausea [9]. Long-term use of large doses of vitamin A in young children, vitamin A symptoms, mainly liver splenomegaly, red blood cells and white blood cells are reduced, bone marrow growth is too fast and long bones become brittle, prone to fractures. A new Swedish study shows that middle-aged men with high levels of vitamin A in their blood have a much higher incidence of fractures in their old age than those with low levels of vitamin A in their blood. Therefore, for the human body, vitamin A is indispensable and can not be abused. As long as the diet is rich in vitamin A or carotene, it can effectively prevent vitamin A deficiency without additional vitamin A supplement.

Advantage Description

A fat-soluble vitamin that is stable to heat, acid, and alkali, and is easily oxidized, and ultraviolet rays can promote its oxidative damage. Vitamin A includes A1 and A2, and A1 is retinol. Vitamin A2, 3-dehydroretinol, has a physiological activity of 40% of vitamin A1.

Detailed Description

Vitamin A promotes growth, reproduction, and maintains various physiological functions such as bone, epithelial tissue, visual and mucosal epithelial secretion. Vitamin A and its analogues have the effect of preventing precancerous lesions. In the absence of growth, it shows growth retardation and dark adaptation ability, which leads to night blindness. Due to dryness, desquamation, excessive keratinization, and decreased secretion of lacrimal glands in the epidermis and mucosal epithelial cells, dry eye disease occurs, and the cornea is softened and perforated and blind. The airway epithelial cells are keratinized and lose cilia, making the resistance less susceptible to infection. The recommended intake of vitamin A in adults (RNI) in China is 800 ug retinol activity equivalent per day, and female is 700 ug retinol activity equivalent per day. [2] Foods containing more vitamin A include poultry, livestock liver, egg yolk, and milk powder. Carotene can be changed into vitamin A, reddish yellow and dark green vegetables in the small intestine mucosa, and contains more carotene in fruits.
