Excessive use of these four vitamins or poisoning

　   B vitamins

　　B vitamins include 9 kinds of vitamins B1. B2. niacin, pantothenic acid, folic acid, B6. B12. biotin and choline, which mainly participate in various synthetic and catabolic processes in the body in the form of coenzyme.

　　It is closely related to the release of energy and the formation of blood cells.

　　Taking a large amount of B vitamins may also cause restlessness, fatigue, loss of appetite, occasionally skin burning, itching and other side effects.

　　vitamin A

　　Excessive intake of vitamin A can be divided into acute poisoning and chronic poisoning.

　　If vitamin A is ingested and overdosed in a short time, it can form a kind of acute vitamin A poisoning symptoms, such as dizziness, lethargy, headache, vomiting, diarrhea, etc;

　　Chronic poisoning refers to the symptom of taking too much vitamin A in a long period, but the excess is not serious, and vitamin A is slowly accumulated and displayed.

　　The symptoms are bone pain and joint pain, swelling, skin itching, fatigue, limb weakness, excitement, abdominal pain, female menstruation, etc.

　　vitamin E

　　Vitamin e, also known as tocopherol, inhibits the oxidation of fatty acids, thereby reducing the formation of lipofuscin and protecting cells from free radical damage.

　　The recommended daily intake for adults is 14 mg of total tocopherol, while the elderly need to increase the intake of vitamin e to less than 300 mg.

　　The toxicity of vitamin E is relatively small. Adults take 100~800mg of vitamin E orally every day, without obvious poisoning symptoms and biochemical changes.

　　However, long-term intake of 1000 mg/day of vitamin E may lead to severe poisoning symptoms, such as thrombosis, hypertension, pulmonary embolism and other symptoms.

　　vitamin D

　　Vitamin D can be supplemented by sun exposure (rather than glass exposure), which is usually low in food content, including cod liver oil, high-fat fish, fish eggs and animal liver.

　　If vitamin D is taken in large quantities for a long time, the intestinal absorption of calcium and phosphorus will increase, which will easily lead to high blood calcium concentration and even lead to vitamin D poisoning.

　　If vitamin D poisoning occurs, there will be abnormal thirst, skin itching, anorexia and other symptoms, which must be treated in time.

　　reminder

　　In life, we can extract vitamins by taking food supplements as far as possible to ensure balanced intake of nutrients, but we must not use too much. It is more effective to take symptomatic supplements.
