What will happen if you eat too much vitamin C?

　　Experts said: It was previously believed that vitamin C has very little toxicity. Even if it is taken orally in excess, only mild nausea, vomiting, diarrhea wait. But in recent years, according to clinical Observation and animal experiments have proven that long-term overdose of vitamin C will cause a series of adverse reactions. The author consulted a variety of domestic and foreign information, which is summarized as follows:

　　(1) Research by foreign authoritative institutions shows that anyone who wants to increase cold People who have long-term and excessive intake of vitamin C because of their resistance will have the content of vitamin C in their body reduced. This is because taking large doses changes the regulatory mechanism of vitamin C in the body and accelerates its decomposition and excretion. Therefore, once the drug is stopped, it may lead to drug withdrawal reaction and early symptoms of scurvy (including swelling and bleeding of gums, loose teeth).

　　(2) Children taking large doses of vitamin C during the growth period can make children susceptible to bone diseases in the future, because large doses of vitamin C can damage the formation process of osteoblasts.

　　(3) Taking more than 4 grams of vitamin C daily can cause urinary tract calcium oxalate stones and kidney stones after one week. In severe cases, it can cause hematuria and renal colic. Oxalate stones occur because excessive vitamin C makes urine acidic.

　　(4) Large doses of vitamin C can resist the anticoagulant effects of heparin and dicoumarol, leading to thrombosis, which makes people with existing cardiovascular and cerebrovascular diseases more susceptible to cerebral infarction (stroke).

　　(5) Ingesting large doses of vitamin C can increase urinary excretion, and its reducing properties can produce false positive reactions in urine sugar, which hinders the diagnosis and treatment of diabetic patients and the accurate control of the dosage of hypoglycemic drugs.

　　(6) Large doses of vitamin C can reduce women’s fertility and affect embryo development. Because large doses of vitamin C can easily form an "acidic constitution" in the body, which is not conducive to the development of reproductive cells.

　　(7) When the daily dose of vitamin C exceeds 3 grams, it can increase intestinal peristalsis and cause abdominal cramps and diarrhea in some people.

　　(8) Taking vitamin C and foods containing vitamin B12 at the same time can destroy a considerable amount of vitamin B12.； After a large amount of vitamin B12 is destroyed, people are susceptible to anemia。
