Is there any side effect for taking lots of vitamin C supplement?

Vitamin C is basically easy to absorb. It was previously believed that the toxicity of vitamin C is very small, and even if it is taken orally, only mild nausea, vomiting, diarrhea, etc. will occur. However, in recent years, according to clinical observations and animal experiments, it has been proved that excessive intake of vitamin C will cause a series of adverse reactions.

1. Research by foreign authoritative institutions has shown that people who want to increase their resistance to colds and take vitamin C for a long time and overdose will reduce the content of vitamin C in their bodies. This is because taking large doses changes the regulatory mechanism of vitamin C in the body, accelerating the decomposition and excretion. Therefore, once the drug is discontinued, it may lead to a withdrawal reaction and early symptoms of scurvy (including swollen and bleeding gums, and loose teeth).

2. High-dose vitamin C can counteract the anticoagulant effect of heparin and dicoumarin, leading to thrombosis, which makes people with existing cardiovascular and cerebrovascular diseases more prone to cerebral infarction (stroke).

3. Taking large doses of vitamin C in growing children can make children susceptible to bone disease in the future, because large doses of vitamin C will damage the formation process of osteoblasts.

4. The simultaneous intake of vitamin C and foods containing vitamin B12 can destroy a considerable amount of vitamin B12; and after a large amount of vitamin B12 is destroyed, people are susceptible to anemia.

5. Ingestion of large doses of vitamin C can increase urinary excretion, because its reducibility can produce false-positive reactions of urine sugar, which hinders the diagnosis and treatment of diabetic patients and the precise control of the dosage of hypoglycemic drugs.ascorbic acid 500mg supplier -NhSquirrel

To sum up, although vitamin C is an essential substance to maintain human metabolism and has important clinical value in the prevention and treatment of various diseases, excessive intake is useless or even harmful to the human body.
