3, children take too much during their growth period, which is prone to bone diseases.
4, a one-time intake of VC2500-5000 mg or more, may lead to a large number of red blood cells rupture, hemolysis and other critical phenomena.
(The above question refers to the traditional acidic vitamin C. ..
If it was acid-free vitamin C, such a thing would not have happened.

Recently, Austrian scientists have warned that the abuse of vitamin C will weaken human immunity.
Professor Goldberg of the Institute of Medicinal Chemistry of the University of Vienna recently told the press that studies have proved that vitamin C plays an important role in the composition of neurotransmitters such as protein and adrenaline in human connective tissue.
When people are infected or have other inflammations, the demand for vitamin C also increases, but we must be very cautious when using large doses of vitamins.
Professor Goldberg warned that increasing the dose of vitamins to more than once a day is not only meaningless, but also likely to backfire.
Because there is too much vitamin C around white blood cells, it can not only prevent white blood cells from destroying germs, but also protect germs and cancer cells.
Excessive vitamin C can not only enhance human immunity, but also weaken it.
Professor Goldberg specially reminded us not to take vitamin C casually like eating jelly beans.
But if you eat more vegetables and fruits rich in vitamins, such as oranges, peppers, tomatoes or potatoes, you don't have to worry about taking too much vitamin C.
At the same time, American researchers have found that the abuse of vitamin C may accelerate arteriosclerosis.
What is the function of VC sugar, which is very popular in Korea? I believe many people have taken pills containing vitamin C when they have a cold, but do you know what vitamin C is? What effect does it have on the human body? Next, let the author unveil the mystery of vitamin C for you.
Vitamin C is acidic in aqueous solution, so it is also called ascorbic acid.
It is an essential trace substance for human body. As an efficient reducing agent, it plays an important role in many biochemical reactions of human body. When it is oxidized, vitamin C will become dehydrovitamin C. If it continues to be oxidized, it will lose its physiological effect.
It is such a substance with a small demand, but it has a great effect on the human body, so let's look at the "power" of vitamin C.
Vitamin C is a reducing agent and dehydrovitamin C is an oxidizing agent, both of which exist in the body.
Therefore, vitamin C and dehydrovitamin C can help a series of redox reactions, such as: 1, and treat and prevent iron deficiency anemia and megaloblastic anemia (diseases caused by folic acid deficiency or vitamin B 12) respectively by promoting the absorption of iron and tetrahydrofolate.
The mechanism of the former is that vitamin C can promote the reduction of trivalent iron ions to divalent iron ions, which is beneficial to the body's absorption of iron.
The mechanism of the latter is to promote the reduction of folic acid to tetrahydrofolic acid, thus preventing and alleviating megaloblastic anemia.
2. By reducing the cystine of protein in food to cysteine, it can promote the production of antibodies in vivo, thus improving the immune environment in vivo and enhancing immunity.
When people catch a cold, their metabolism is fast, so they need a lot of vitamin C to participate in the reaction, and their immunity needs to be enhanced. It is not difficult to understand why people who have a cold need to supplement vitamin C.
But children are small eaters and picky eaters, and it is quite difficult to achieve enough VC intake.
Therefore, today I recommend a popular VC candy in Nidong, Korea-MyNi vitamin C chewable tablets.
Sweet and sour, excellent taste, deeply loved by adults and children.
What effect does Korean vc film have on people's health? One tablet of vc a day can supplement vitamin C. If it is used to treat vitamin C deficiency, take two tablets a day. If you take a large dose of vc every day, you can't reduce it at once, and you are prone to scurvy, so you should gradually reduce it.
How long is the shelf life of Jeju Island vc film? Generally 1-2 years.
There are many vitamin C products on the market, including vitamin C tablets and vitamin compound preparations. Generally, the shelf life is about 1-2 years.
However, the shelf life of specific products is still based on official product data, so when purchasing vitamin C products, we must pay more attention to its production date and shelf life.
Its main function is to maintain normal metabolism, promote collagen tissue synthesis, participate in hematopoiesis and antioxidation.
Clinically, it is generally used as an antidote (lead compounds, arsenic compounds, benzene, bacterial toxins, etc. ), vitamin C (lowering blood cholesterol) is also given in the clinical treatment of coronary heart disease.
Excessive oral intake will lead to diarrhea and abdominal distension, and excessive intake will cause excessive absorption of iron, reduce the bactericidal ability of white blood cells, destroy red blood cells and form urinary calculi.
The recommended intake of vitamin C for adults is 1000mg/ day (diet+supplement), and the maximum tolerable intake is1000 mg/day.
Vitamin c must not be synthesized by the human body and must be supplemented from the diet. If you can't take 5 servings of fruits and vegetables every day, you can take a small amount of vitamin C nutritional supplements.
Vitamin C can reduce the oxidative stress in the body, enhance the ability of the immune system and prevent colds. It is suggested to supplement vitamin C, especially for certain specific groups, such as the elderly, people with weak immune system, smokers, people with heavy life pressure, athletes and pregnant women.
If you take a large dose of vitamin C products for a long time and suddenly stop taking them, there will be symptoms of deficiency, which will lead to vitamin C deficiency.
It is suggested that those who take large doses of vitamin C for a long time can switch to food-grade multivitamins for continuous maintenance and gradually stop using them.
No matter which country's vitamin C efficacy is exactly the same, it mainly depends on whether the intake is appropriate. The product you mentioned has been tested to show that the content of vitamin C is 3.2%, and one tablet contains about vitamin C48mg. Therefore, combined with your daily diet, 1-2 tablets is almost enough for adults.
A healthy adult only needs 100 mg of vitamin C every day, which can basically meet the needs of the body to maintain normal functions. Adults eat more than 250 grams of grain, 125 grams of meat and fish eggs, more than 300 grams of vegetables and more than 200 grams of fruit every day, which can basically ensure all kinds of vitamins needed by the human body.
Except for special groups (infants, pregnant women, lactating women, etc.). ) people who may need extra small doses of vitamin c supplement, food supplement takes precedence over medicine supplement.

The main components of bones promote the formation of collagen, which is indispensable for strong bones of infants.
4. Vitamin B 1 is a nutritional source to get energy from carbohydrates and save skin and mucous membranes.
Vitamin B 1 is called a mental vitamin, because vitamin B 1 has a good influence on nervous tissue and mental state; Vitamin B 1 deficiency can easily cause various beriberi.
5. Will vitamin B2 be phosphorylated after entering the human body? _ _ 涑涑浶涑涑涑涑涑涑涑涑涑涑
Dehydroalcohol is an important substance to maintain the respiration of tissues and cells.
Without it, the metabolism of substances in the body is disordered, resulting in angular stomatitis, dermatitis, glossitis, seborrheic dermatitis, conjunctivitis and keratitis.
6. Vitamin B6 is a nutrient source that can get energy from protein to save skin and mucous membrane.
Vitamin B6 is a coenzyme of many important enzyme systems in the body, which participates in physiological processes such as amino acid decarboxylation, tryptophan synthesis, sulfur-containing amino acids and unsaturated fatty acid metabolism, and is an essential nutrient for the normal development of animals and the reproduction of bacteria and yeast.
Lack of vitamin B6 can easily lead to anemia, seborrheic dermatitis and glossitis.
7. Folic acid is a nutritional source for normal fetal development.
8. Nicotinic acid, also known as vitamin B3, is a water-soluble vitamin and belongs to vitamin B group.
Nicotinic acid is converted into nicotinamide in human body. Nicotinamide is a component of coenzyme I and coenzyme II, which is involved in lipid metabolism, oxidation of tissue respiration and anaerobic decomposition of sugar.
Vitamins B 1, B2, B3, B5, B6, B7, biotin and folic acid can improve children's metabolism and have a good effect on the development of children's nervous system.
A story about venture capital.
1536, French explorer JacquesCartier went upstream to Quebec for the winter after discovering the St. Lawrence River.
Twenty-four people in the expedition died of scurvy, and many others were seriously ill.
An Indian taught them to drink a kind of tea soaked in Thujaoccidentalis and cured them.
Later, it was found that the leaves of this tree contained 50 mg of vitamin C per100g.
1747, James Linde, a British naval doctor, made this famous experiment on board. 12 sailors with severe scurvy eat exactly the same food, and the only different medicine is the prescription that was said to be scurvy at that time.
Two patients eat two oranges and a lemon every day, the other two drink apple juice, and the other two drink dilute sulfuric acid, sour vinegar, seawater, or other drugs that people thought could cure scurvy at that time.
Six days later, only two people who ate fresh citrus fruits got better, and the others were still sick.
Linde continued his research, and in 1753, he published the book ATreatiseonScurvy.
Vc is in China
The people of China play a key role in the fight against the virus.
China, with a large population and dense population, is the area where the virus is most likely to spread, and it is also the area most affected by the virus.
For example, many influenza viruses originated in China, SARS virus first appeared in China, and 90% of people who died of SARS came from China.
Vitamin C has high application value in resisting virus and preventing viral infectious diseases.
At present, China has gradually become a leading position in vitamin C production. However, the average dose of vitamin C taken by China people is far lower than that of Europe, America and Japan.
If we generally recognize the principle of vitamin C in preventing virus infection and take it in moderation, we can prevent the spread of many viruses.
The real role of vitamin C will be manifested in more serious viral infectious diseases such as avian influenza, SARS and AIDS.
Suitable for people:
1, people who get tired easily.
2. People who work in polluted environment.
People with high vitamin C content in the body hardly absorb harmful elements such as lead, cadmium and chromium.
3. People who like smoking.
Smokers eat more foods containing vitamin C, which helps to improve the resistance of cells, maintain the elasticity of blood vessels and eliminate nicotine in the body.
4. People who engage in strenuous exercise and high-intensity labor.
These people will lose a lot of vitamin C due to excessive sweating and should be supplemented in time.
5. Patients with scurvy.
This disease is due to the lack of vitamin C in diet, which leads to poor formation of hoof tissue and increased brittleness of capillary wall. We should eat more foods rich in vitamin C.
6. People with spots on their faces.
Vitamin C has antioxidant effect, and vitamin C supplementation can inhibit the formation of pigment spots and promote their regression.
7. People who take drugs for a long time.
Take aspirin, sleeping pills, anticancer drugs, tetracycline, calcium products, birth control pills, antihypertensive drugs, etc. , will reduce the body's vitamin C, causing other adverse reactions. Vitamin c should be supplemented in time.
8. Cataract patients.
Vitamin C is a nutrient element of intraocular lens, and insufficient intake of vitamin C is one of the factors leading to cataract, so patients should take more vitamin C.
Management method:
Children take 1-2 capsules daily; Adults take 1-3 capsules a day.
Storage method: room temperature storage.
Precautions:
VC can't be eaten with pig liver, milk and shellfish.
Vc has the functions of detoxifying, protecting liver, resisting allergy, promoting wound healing and increasing body resistance, and can be used for many diseases.
1, pig liver
Vc is easily destroyed by oxidation when it meets trace metal atoms, especially copper ions.
Pig liver is a food rich in copper, and the copper content per100g is about 2.
6 mg, if taken with Vc at the same time, copper ions in pig liver can make Vc lose its original biological function, as well as sheep liver and bovine liver.
2。
milk
Vc is easily oxidized, acidic and highly reducing.
Milk is rich in vitamin B2, which has a certain oxidation effect. When taken at the same time, Vc is easily oxidized by vitamin B2, while vitamin B2 decreases and loses its function.
3。
Shellfish aquatic products
There are many arsenic compounds in shellfish aquatic products, but these arsenic compounds exist in pentavalent form and will not have any influence on human body. However, taking Vc while taking these products, the interaction between them can convert pentavalent arsenic into trivalent arsenic, which may be poisoned if eaten! ! !
