Vitamin B2 is a trace element, and the human body has little demand for it. According to the dietary nutrition guidelines of China residents, adults need 1mg- 1.2mg of vitamin B2 every day. Vitamin B2 is widely found in animal viscera, milk and dairy products, whole grains, egg yolk, green vegetables and other foods, with the most content in dry yeast. Therefore, people who can eat normally do not need to supplement vitamin B2. However, it should be noted that frequent consumption of polished rice and white flour and lack of miscellaneous grains will lead to insufficient intake of vitamin B2 and unhealthy living habits such as high-sugar and high-fat diet, smoking, drinking and drinking coffee. This will lead to excessive intake of vitamin B2 and improper cooking methods such as frying and frying, which will lead to a large loss of vitamin B2 in food. If these people have symptoms related to the mouth, eyes and external genitalia, they can be properly supplemented with vitamin B2 under the guidance of a doctor.
Vitamin B2 has strong water solubility, and can be quickly excreted with urine through the kidney after taking it. Urine is yellow, safe and well tolerated. However, taking a large amount of vitamin B2 for a long time will cause eye side effects, such as eye pain, photophobia, blurred vision, corneal opacity, corneal swelling, punctate keratitis and progressive keratoconus. And even induce serious side effects such as ulcerative keratitis. Therefore, it is recommended that you remember to use vitamin B2 according to the doctor's advice, and don't take it at will.
Vitamin B2 is water soluble. If taken before meals, the drug will be absorbed quickly after reaching the intestine, and the blood drug concentration will rise rapidly. Before vitamin B2 is fully utilized, it will be excreted with urine through the kidney. If taken after meals, food can delay the absorption of vitamin B2 in the intestine, and drugs can be absorbed and utilized more fully, so it is recommended to take vitamin B2 after meals. In addition, vitamin B2 has a short half-life, so it is recommended to take 1-2 tablets (5mg- 10mg) once, three times a day, and the maximum daily dose should not exceed 6 tablets.
Vitamin B2 participates in cell growth and metabolism, is an essential nutrient for tissue metabolism and repair, and can promote the regeneration of healthy cells, which may be helpful for the treatment of cancer, but it cannot replace conventional treatments such as radiotherapy and chemotherapy. Vitamin B2 has no obvious regulating effect on human immune function, nor can it fight against cancer cells. In addition, studies have found that vitamin B2 has antioxidant activity, which can inhibit oxidative damage, prevent oxygen free radicals from attacking human protein, fatty acids and genetic material DNA, and help to prevent cancer. However, it is often necessary to take large doses of vitamin B2 for a long time, and taking large doses of vitamin B2 will obviously increase the burden on the kidneys and may also induce eye side effects, which is not worth the candle.
Vitamin B6 is also a water-soluble B vitamin, also known as pyridoxine, which is widely found in eggs, milk, animal liver, chicken breast, lean beef, tuna, peanuts, bananas and other foods. Adults need about 2 milligrams of vitamin B6 every day. Vitamin B6 is also a component of coenzyme, which participates in the metabolism of sugar, protein, fat and folic acid, promotes the synthesis of white blood cells and hemoglobin, and maintains the normal hematopoietic function of the body. It can also participate in the synthesis of neurotransmitters and genetic materials to maintain the normal nervous function of the body. Lack of vitamin B6 can lead to chapped lips, seborrheic dermatitis, insomnia, anemia and other diseases.
Vitamin B6 and vitamin B2 are both water-soluble B vitamins, and their differences mainly lie in their indications. Vitamin B6 is mainly used to prevent and treat vitamin B6 deficiency, such as chapped lips, seborrheic dermatitis, insomnia, anemia, depression and anorexia. It can also be used to relieve vomiting during pregnancy, peripheral neuritis, leukopenia, anemia, lactating women, hyperhomocysteinemia, Parkinson's syndrome, dysmenorrhea and urinary calculi. Vitamin B2 is mainly used to prevent and treat vitamin B2 deficiency, such as glossitis, angular stomatitis, chapped lips, conjunctivitis, bursitis and seborrheic dermatitis. It is also suitable for adjuvant treatment of progressive keratoconus, corneal swelling after refractive surgery, migraine and lactic acidosis.
