Main physiological functions of benefits: 1. Promote the biosynthesis of collagen. Conducive to faster healing of tissue wounds;

2. Promote the metabolism of tyrosine and tryptophan in amino acids and extend the life of the body.

3. Improve the utilization of iron, calcium and folic acid.

4. Improve the metabolism of fats and lipids, especially cholesterol, and prevent cardiovascular disease.

5. Promote the growth of teeth and bones and prevent gum bleeding.

6. Enhance the body’s anti-stress ability and immunity to the external environment. Disadvantages 1. Taking too much VC supplements in the short term may cause side effects such as polyuria, diarrhea, and skin rashes;

3. Overdosage during the growth period of children may easily cause bone diseases.

4. Ingesting more than 2500-5000 mg of VC at one time may cause a large number of red blood cells to rupture and lead to critical phenomena such as hemolysis.

(The above question refers to traditional acidic vitamin C. If it were acid-free vitamin C, such a thing would not happen.)

Recently, Austrian scientists warned that , Abuse of vitamin C will weaken human immunity.

Professor Goldberg from the Institute of Medical Chemistry at the University of Vienna recently told the press that research has proven that the role of vitamin C in the composition of human connective tissue proteins and neurotransmitters such as adrenaline cannot be underestimated. . When the human body is infected or has other inflammations, its need for vitamin C also increases, but you must be very cautious when using large doses of vitamins. ?

Professor Goldberg warned that increasing the dosage of vitamins to multiple times a day is not only meaningless, but may also be counterproductive. Because too much vitamin C around white blood cells not only prevents white blood cells from destroying germs, but also protects germs and cancer cells. Excessive vitamin C not only fails to enhance the body's immunity, but will weaken it. Professor Goldberg especially reminds us not to take vitamin C casually like eating jelly beans.

But if you eat more vitamin-rich vegetables and fruits such as oranges, peppers, tomatoes or potatoes, you don’t have to worry about overdose of vitamin C.

At the same time, American researchers have found that abuse of vitamin C may accelerate arteriosclerosis.
