The University of California reported that people who want to increase their resistance to colds and take vitamin C for a long time will have a decrease in the content of vitamin C in their bodies. This is due to the fact that taking a large dose of vitamin C changes the regulatory mechanism of vitamin C in the body, accelerates the decomposition and excretion of vitamin C, and once stopped, it can cause a withdrawal reaction and early symptoms of scurvy, such as swollen gums, bleeding, loose teeth, etc.
High doses of vitamin C in growing children can predispose children to bone disease later in life.
Trials have shown that urinary tract calcium oxalate stones and kidney stones may occur after one week of oral administration of vitamin C4 grams daily.
High-dose vitamin C counteracts the anticoagulant effects of heparin and dicoumarin, leading to thrombosis.
Intake of high-dose vitamin C can increase urine excretion, and its reducing nature can produce a false-positive reaction to glucose in the urine, which hinders the diagnosis and treatment of diabetic patients and the accurate control of the dose of hypoglycemic drugs.
High doses of vitamin C can reduce fertility in women and affect embryonic development. The results of animal experiments show this phenomenon very clearly.
Doses of vitamin C exceeding 3 grams per day can lead to increased bowel movements, causing abdominal cramps and diarrhea.
Vitamin C can destroy a considerable amount of vitamin B12 when ingested at the same time as foods containing vitamin B12, and when vitamin B12 is destroyed in large amounts, people are susceptible to anemia.
Intravenous administration of vitamin C in high concentrations can produce severe hemolytic reactions.
To sum up, although vitamin C is a substance necessary for maintaining human metabolism and has important clinical value for the prevention and treatment of a variety of diseases, excessive intake is not beneficial to the human body, and even harmful, so it must be remembered: do not abuse it.

1. Milk.
Vitamin C is acidic and highly reducible, and is highly susceptible to oxidation. Milk is rich in vitamin B2 with a certain oxidizing property, and vitamin C is easily oxidized by vitamin B2 when taken at the same time, and vitamin B2 is reduced, both of which lose their effectiveness at the same time, and cannot achieve the purpose of vitamin supplementation.
2. Aspirin.
The combination of aspirin and vitamin C will reduce the absorption of vitamin C in the intestine, but vitamin C does not affect the efficacy of aspirin, so when both drugs are to be taken, vitamin C should be taken first, at least 1 hour apart before taking aspirin.
3. Certain nutrients.
Vitamin C can affect the absorption and utilization of vitamin B12, resulting in vitamin B12 deficiency and can increase the need for vitamin B1, so it needs to be taken at least 2 hours at a staggered time. Folic acid and vitamin C are easy to undergo redox reaction when taken at the same time, and folic acid decomposes faster in an acidic environment, resulting in the weakening of the effect of the two drugs.
4. Other drugs.
Long-term use of large amounts of VC can cause oxalate binding, and if it is taken with calcium tablets for a long time, it has more chance of causing stones and should be avoided. In addition, vitamin C has an anticoagulant effect against heparin and warfarin, which can cause a shortening of the prothrombin time and weaken the effect of anticoagulant drugs. Both drugs must be taken at least 2 hours apart.
