Generally speaking, nutritionists suggest that the daily intake of VE should be within 400 international units, that is, 10- 100 mg. If the single dose is too large, it should be taken under the guidance of a dietitian or doctor.
Vitamin a is also called retinol.
Vitamin A is a component of rhodopsin that feels weak light in visual cells. Rhodopsin is composed of opsin and 0- cis retinoic acid, which is related to dark vision.
Animal liver is rich in vitamin A, but human body lacks vitamin A, which affects the dark adaptation ability, such as children's developmental retardation, dry skin, dry eye, night blindness and so on.
The minimum daily vitamin A requirement of normal adults is about 3,500 international units (0.3 micrograms of vitamin A is equivalent to 1 international unit), and that of children is about 2,000-2,500 international units.
If you lack VA, you can eat more animal liver. If you lack too much, you should take some pills in moderation.

Vitamin C participates in many reactions in the body, such as redox process, and plays an important role in biological redox and cell respiration. From the tissue level, the main function of vitamin C is related to the synthesis of intercellular substance. Including collagen, the matrix of teeth and bones, and the connection between capillary endothelial cells. Therefore, when vitamin C deficiency causes scurvy, it is accompanied by collagen synthesis defect, which is characterized by difficult wound healing, tooth formation disorder, capillary injury causing a large number of blood stasis points, and blood stasis points fuse to form ecchymosis.
