Vitamin B2, also known as riboflavin, is slightly soluble in water and widely distributed in nature. It is an essential nutrient for mammals. Its coenzyme forms are flavin mononucleotide and flavin adenine dinucleotide. What are its common functions and functions? The following editor will introduce it to you.

　General effects of riboflavin

　　1. Promote development and cell regeneration;

　　2. Promote the normal growth of skin, nails and hair;

　　3. Help prevent and eliminate inflammatory reactions in the mouth, lips, tongue and skin, collectively referred to as oral reproductive syndrome;

　　4. Improve vision and reduce eye fatigue;

　　5. Affect the body's absorption of iron;

　　6. Combine with other substances to affect biological oxidation and energy metabolism.

　　The special effect of riboflavin

　　1. For the treatment of angina pectoris

　　For people suffering from coronary heart disease, myocardial ischemia and angina pectoris, if they take vitamin B2 75 mg each time, 3 times a day, after one month of medication, the frequency of angina pectoris can be reduced or even disappeared. This is because vitamin B2 improves the blood supply to the heart.

　　2. Used to prevent migraine

　　Researchers in Belgium and Luxembourg found that high-dose vitamin b2 supplementation can reduce the frequency and duration of migraine headaches. Migraines are caused by reduced energy reserves in brain cells. Vitamin B2 can improve the potential of mitochondria in brain cells. Therefore, taking vitamin B2, 400 mg once a day, can effectively treat migraines.

　　3. Prevention and treatment of cancer

　　Scientists have found that lack of vitamin b2 can enhance the carcinogenic effect of chemical carcinogens. Therefore, supplementing more vitamin B2 in daily life can prevent and treat cancer. The usual amount of vitamin B2 supplementation is: 10 mg each time, orally 3 times a day.

　　Food Sources of Riboflavin

　　Vitamin B2 is a water-soluble vitamin that is easy to digest and absorb. The amount excreted increases or decreases with the needs of the body and may increase or decrease with the loss of protein; it does not accumulate in the body, so it is often supplemented with food or nutritional supplements . It only exists in dairy products and the liver and kidney of animals. In addition, egg yolks, seaweed, carrots, lettuce, shiitake mushrooms, and eels that we usually eat are also rich in vitamin B2.

　　People who need riboflavin

　　1. During pregnancy and lactation, women who take contraceptives need more vitamin B2. 1.6 mg is required during pregnancy, 1.8 mg for the first 6 months and 1.7 mg for the following 6 months during breastfeeding;

　　2. People who do not often eat lean meat and dairy products should increase the intake of vitamin B2;

　　3. People who are in a state of mental stress for a long time need to supplement the dosage of complex vitamin B2;

　　4. People who have long-term diet control due to ulcers or diabetes are more likely to have vitamin B2 deficiency (if a person is suffering from a special disease and is receiving treatment, if he wants to change the diet prescribed by the doctor, he must discuss it with the doctor) ;

　　5. The recommended daily intake for adults is 1.7mg.

　　Symptoms of Riboflavin Supplementation

　　Excessive intake may cause itching, numbness, nosebleeds, burning sensation, tingling, etc. If you are taking anticancer drugs, such as methotrexate, excess b2 will reduce the effectiveness of these anticancer agents.
