Vitamin B2, also called riboflavin,
1. Promote development and cell regeneration.
2. Participate in cell growth and metabolism.
3. Cooperate with other substances to participate in various metabolism.
4. Promote growth and development, and maintain the integrity of skin and cell membrane.
5. Prevention and elimination of oral reproductive syndrome.
6. Promote the normal growth of skin, nails and hair.
7. Promote the body's absorption of iron, which can prevent anemia.
8. Improve eyesight and reduce eye fatigue
Lack of vitamin B2 can lead to ulcers.
When B2 is deficient, the human body can't produce enough skin and mucosal cells to replace the cells that have been metabolized, and a gap is created, which is an ulcer.
It happens in the esophagus, which is an esophageal ulcer.
It happens in the stomach, which is a gastric ulcer.
It happens in the intestine, which is an intestinal ulcer.
If the ulcer surface can't heal for a long time, it will be infected by bacteria and produce inflammation. Simply using anti-inflammatory drugs can only temporarily control the proliferation of bacteria and can't heal the ulcer.
Vitamin B2 has a wide range of functions
1. Treatment of angina pectoris and coronary heart disease: Patients with myocardial ischemia and angina pectoris take 75mg of vitamin B2 three times a day, and the frequency of angina pectoris is reduced after 2-3 months.
2. Relieve migraine: Migraine is caused by decreased energy reserves of brain cells or strong cerebral vasospasm. Taking 200 ~ 400 mg of vitamin B2 every day according to the doctor's advice can effectively prevent and treat migraine, at least reducing the frequency and degree of attacks.
3. Improve sexual life: Therefore, women (especially during the growth period) should pay attention to supplementing multivitamins, including not only vitamin B2, but also folic acid.
4. Prevention and treatment of prostatic hyperplasia: Pharmacological research shows that vitamin B2 has diuretic and detumescence effects, which is beneficial to eliminate symptoms such as dysuria. Patients with benign prostatic hyperplasia can take 50 mg of vitamin B2 every day, and their symptoms can be improved after half a year.
5. Enhance cold tolerance: Vitamin B2 combined with vitamin E and iron can enhance the cold tolerance of human body.
Vitamin B2 is so important, how can we supplement enough vitamin B2?
Foods containing vitamin B2
1. You can choose milk and its products, animal viscera (liver, kidney and heart, etc.), egg yolk, and a variety of fish (especially eel and crucian carp, etc.).
2. Vegetables such as spinach, carrots, mushrooms, laver, eggplant, celery and tomatoes, and fruits such as oranges and tangerines.
3. Some people who are seriously deficient in vitamin B2 should be supplemented with pharmaceutical-grade vitamin B2 tablets or vitamin B complex tablets under the guidance of doctors and pharmacists.
4. It is harmful to the body to master the dosage of medicine badly. There is a natural B vitamin. It is a perfect vitamin supplement. Look at the function of B vitamins!
People often come into contact with B vitamins, such as vitamin B 1, vitamin B2, vitamin B6, vitamin B 12, pantothenic acid, nicotinic acid and folic acid. In addition, choline and inositol are also regarded as members of this big family.
B vitamins are essential nutrients for all human tissues and the key to energy release from food. They have many characteristics in common, such as:
Are water-soluble vitamins;
Can not be stored in large quantities in the body;
The retention time in the body is only a few hours, and it must be supplemented every day.
In addition, B vitamins are all coenzymes, which participate in the metabolism of sugar, protein and fat in the body, so they are classified as a family.
So, what are the main physiological functions of B vitamins in the human body?
B vitamins can regulate human metabolism and participate in energy release. Any physiological activity of the human body is the result of the interaction of various nutrients. The metabolism of any productivity nutrient, whether carbohydrate, fat or protein, needs the participation of B vitamins.
Maintain the health of skin and mucosa
B vitamins can maintain the health of skin and mucous membrane, and serious lack of B vitamins may cause health damage to skin and mucous membrane. Such as:
Lack of vitamin B2 can lead to oral and reproductive system syndrome, typical manifestations include map tongue, angular stomatitis, oral ulcer and so on.
Nicotinic acid deficiency refers to the damage to the metabolism of poultry caused by the simultaneous deficiency of nicotinic acid and tryptophan, and the main symptom after the deficiency of nicotinic acid is furuncle.
Lack of vitamin B6 may lead to seborrheic dermatitis.
Maintain the normal function of the nervous system
B vitamins can maintain the normal function of the nervous system. If it is lacking, it will bring bad influence. For example, the lack of vitamin B 1 is easy to cause beriberi, which is usually manifested as weakness of lower limbs, anorexia, anorexia, constipation, indigestion and other central and peripheral nervous system damage, and heart failure may occur in severe cases, which is called beriberi heart disease;
"beriberi" ≠ "beriberi, athlete's foot"
"beriberi" is a symptom of peripheral neuritis caused by vitamin B 1 deficiency, while "beriberi and athlete's foot" is a fungal infectious disease.
Prevent anemia
If the human body lacks B vitamins, it will lead to anemia. For example, if the human body lacks vitamin B6, it will cause small cell anemia, and lack of vitamin B 12 and folic acid will cause megaloblastic anemia.
Prevention of arteriosclerosis
Now scientific research has confirmed that the increase of plasma homocysteine concentration is directly related to atherosclerosis. Therefore, from this perspective, B vitamins are beneficial to prevent arteriosclerosis and maintain cardiovascular health.
Prevention of fetal neural tube malformation
Folic acid is closely related to the differentiation and development of fetal nervous system, which occurs in the early pregnancy. Often at this time, pregnant women themselves may not know that they are pregnant, so they may ignore folic acid supplementation and affect the normal differentiation and development of the fetal nervous system. Therefore, it is suggested that female friends should pay special attention to the adequate supplement of folic acid when preparing for pregnancy.
Therefore, supplementing B vitamins is equivalent to supplementing all water-soluble vitamins. It can't be stored in large quantities in the body, and it stays in the body for only a few hours, so it must be replenished every day.
