What happens when you eat more vitamin C?

We all know that vitamin C has a great effect on the health of the body. Vitamin C can promote bowel movements, but large doses can cause diarrhea, hyperacidity, and reflux of gastric juice. Let's learn about it together.

What happens when you eat more vitamin C?

Vitamin C eats more, and the side effects are still quite large. Research shows that when the daily amount of vitamin C is between 1 and 4 grams, it will cause all kinds of adverse reactions: If the amount exceeds 5 grams, there will be hemolysis and even life. Danger. Pregnant women taking it in large quantities may also suffer from miscarriage or stillbirth. Too much vitamin C intake can have the following side effects:

1. Vitamin C is an acidic substance, which can cause a decrease in the pH of urine after taking it in large amounts. Urine has an obvious increase in oxalate and urate, and it is easy to form kidney stones.

2. Vitamin C can promote bowel movements, large doses can cause diarrhea, hyperacidity, reflux and other gastric juices.

3. Intravenous injection of large doses of vitamin C can cause venous thrombosis, hemolysis or coagulation in the blood vessels, and severe cases can be life-threatening. Injection can also cause allergies, injections of local pain or tissue necrosis.

The role of vitamin C

Involvement in hydroxylation

Hydroxylation is an essential step in the synthesis or decomposition of many important substances in the body. Vitamin C must be involved in the hydroxylation process.

1. Promote collagen synthesis. In the absence of vitamin C, collagen synthesis is impaired, resulting in scurvy.

2. Promote the synthesis of neurotransmitters (5-hydroxytryptamine and norepinephrine).

3. Promote steroid hydroxylation. Patients with high cholesterol should supplement sufficient amounts of vitamin C.

4. Promote the hydroxylation and detoxification of organic substances or poisons. Vitamin C can increase the activity of mixed-function oxidases and enhance the detoxification (hydroxylation) process of drugs or poisons.

Reduction

Vitamin C can be oxidized or reduced in the body, so it can be used as a hydrogen donor or hydrogen acceptor, and plays an important role in the process of redox in vivo.

1. Promote antibody formation. A high concentration of vitamin C helps the cystine in food proteins be reduced to cysteine, which in turn synthesizes antibodies.

2. Promote the absorption of iron. Vitamin C can reduce the hard-to-absorb trivalent iron to easily absorbed ferrous iron, which promotes iron absorption. In addition, sulfhydryl groups such as ferrous iron complex enzymes can also be made active in order to effectively function, so vitamin C is an important auxiliary drug for the treatment of anemia.

3. Promote the formation of tetrahydrofolate. Vitamin C can promote the reduction of folic acid to play a role in tetrahydrofolate, it also has a certain effect on megaloblastic anemia.

4. Maintain the activity of the sulfhydryl enzyme.

Other functions

1. Detoxification. After adding a large amount of vitamin C in the body, it can alleviate the toxic effects of heavy metals such as lead, mercury, cadmium, and arsenic on the body.

2. Prevent cancer. Many studies have shown that vitamin C can block the carcinogen N-nitroso compound synthesis and prevent cancer.

3. Remove free radicals. Vitamin C can be converted into hemi-desoxy ascorbic acid and dehydroascorbic acid by step-by-step feeding of electrons to remove radicals such as super-negative oxygen ions, hydroxyl radicals, organic radicals, and organic peroxy groups; and to restore tocopherol radicals Into tocopherols, the ascorbate free radicals produced by the reaction can be reduced to ascorbic acid by NADH2 system enzymes under certain conditions.

What fruit contains vitamin C

Vitamin C has the functions of decompression, strengthening immunity, and anti-cancer. When subjected to strong psychological stress, the body will consume 8 times more vitamin C than usual, so, as much as possible, daily intake of vitamin C-rich fruit. What vitamins do you need for vitamin C supplements?

There are many fruits rich in vitamin C, such as fresh dates, red fruits, grapefruit, oranges, oranges, lemons, strawberries, persimmons, mangoes, kiwifruit, longan, etc., some fruit vitamin C content is many times higher than ordinary fruits, such as: Oranges are also rich in vitamin C. An orange can almost satisfy the daily amount of vitamin C needed by the body. Oranges contain more than 170 plant compounds and more than 60 flavonoids, most of which are natural antioxidants.
