It has been reported that people who take large amounts of vitamin C for a long time, the vitamin C content in the body does not increase but decreases. Why is that? The so-called “three poisons of medicine”, all medicines have certain toxic and side effects. Vitamins are no exception.
Kaizong Mingyi——Vitamin drugs are mainly used for the prevention and treatment of vitamin deficiency and certain diseases. For patients who do not lack vitamins, taking vitamins is not meaningful. Therefore, in addition to the need to take vitamin C as adjuvant therapy in some special circumstances, vitamin C should not be taken for a long time.
Vitamin C, also known as ascorbic acid, participates in the body’s metabolism, protects the body from the threat of free radicals, and plays a very important role in enhancing the body’s resistance.
However, we must not misunderstand that vitamin C is more beneficial. Especially young friends who want to rely on vitamin C to achieve whitening effect, remember not to take too much.
We all know that vitamin C is low in toxicity, but in large doses, common adverse reactions such as diarrhea, nausea and vomiting, and stomach cramps still occur. If the daily amount exceeds 4 ~ 12g, long-term use will bring burden on the liver and kidneys, acidify the urine, reduce the solubility of uric acid and cystine and precipitate directly from the urine, resulting in uric acid stones or cystine stones.
In addition, oxalic acid is a metabolite of vitamin C. After long-term overdose of vitamin C, oxalate in the urine will increase sharply to form oxalate stones. If you take too much vitamin C to your child, you may experience side effects such as drowsiness, fatigue, restlessness, insomnia, dreams of indigestion and urticaria.
It has been reported that people who take large amounts of vitamin C for a long time, the vitamin C content in the body does not increase but decreases. Why is that? In fact, it is precisely because of this large dose that the regulation mechanism of vitamin C in the body is changed, which accelerates metabolism and excretion. Sudden withdrawal may cause temporary vitamin C deficiency, swollen gums, loose teeth, and scurvy symptoms such as follicular keratosis.
Therefore, it is recommended that patients who take large doses of vitamin C for a long period of time should gradually reduce the dose to withdrawal.
Vitamin C cannot be synthesized in the body, so food is its best source, and the amount in food alone can meet our daily needs.
In vegetables, pepper, bitter gourd, beans, spinach, potatoes, leeks, tomatoes and other vitamin C content is rich. However, as plant tissue contains an ascorbase enzyme, vitamin C in vegetables is easily destroyed after long storage; in addition, vitamin C is easily destroyed in environments that are too acidic, salty, or too hot. Eat the best, vegetable salad is a good choice.
Among fruits, the vitamin C content of winter dates, strawberries, citrus, lemon, kiwi and so on is more. In addition, the animal’s internal organs also contain a small amount of vitamin C.
Based on the needs of each body type and vitamin C, the specific way of taking it is to consult a physician, pharmacist or nutritionist according to the actual situation.
