Vitamin b2 -- involved in sugar, protein, fat metabolism. The main treatment of vitamin b2 deficiency caused by keratitis, uveitis, keratitis, colitis, colitis, scrotum, optic neuritis, conjunctivitis, etc.

Vitamin pp -- involved in sugar and fat metabolism, anti-arrhythmia, dilation of blood vessels, lipid-lowering can be used to prevent and control pellagra, coronary heart disease, viral myocarditis, rheumatic heart disease, vascular spasm, embolism, atherosclerosis, etc.

Vitamin b6 -- involved in amino acid and fat metabolism. Used for vitamin b6 deficiency prevention and treatment of vomiting prevention and treatment of anti-tuberculosis drug isoniazid caused by nerve excitation peripheral neuritis, etc.

Vitamin C

Main physiological functions

1, promote the biosynthesis of collagen. Faster healing of tissue trauma;

2, promote the metabolism of tyrosine and tryptophan in amino acids, prolong 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, to prevent cardiovascular disease.

5, promote the growth of teeth and bones, prevent bleeding from the dental bed.

6, enhance the muscle's ability to resist stress and immunity to the external environment

Vitamin D mainly has the following physiological functions:

1, improve the muscle's absorption of calcium and phosphorus, so that plasma calcium and plasma phosphorus levels to reach the saturation level.

2, Promote growth and calcification of bones and sound teeth;

3, Increase absorption of phosphorus through the intestinal wall and reabsorption of phosphorus through the renal tubules;

4, Maintain normal levels of citrate in the blood;

5, Prevent loss of amino acids through the kidneys.

Vitamin E has the following health effects:

1. Prevention of cardiovascular and cerebrovascular diseases Vitamin E can reduce plasma cholesterol levels, inhibit the proliferation of smooth muscle cells, inhibit platelet adhesion and aggregation, reduce the synthesis of leukotrienes, and intensify the release of prostacyclin, etc. The overall effect of these actions is to prevent atherosclerosis, including coronary arteriosclerosis and cerebral arteriosclerosis.

2. Anti-tumor The anti-tumor effect of vitamin E is related to its antioxidant properties, regulation of immunity, and induction of apoptosis.

3. Prevention and treatment of diabetes and its complications Although large doses of vitamin E does not have a hypoglycemic effect, it can reduce lipid peroxidation, clear free radicals, correct lipid metabolism disorders, and improve platelet and endothelial function, which can prevent and treat the chronic complications of diabetes.

4. Delay Alzheimer's disease and central nervous system dysfunction. 5. Delay aging.

6. Beautify the skin.

There are risks associated with too much vitamin E, including an increased risk of brain hemorrhage.
