Overuse of vitamin C can lead to kidney stones.

Vitamin C is absorbed very quickly into the body. Once saturation is reached, any excess is excreted in the urine. If you consume 1 gram of vitamin C daily for an extended period, you risk developing kidney stones.

In addition, there are many harmful effects if you supplement your body with too much vitamin C.

It will not cause harm if the dosage is correct. Remember these dosages: Normal working adults need 75mg/day; pregnant women need 100-120mg/day.

When used in high doses to treat infections or prevent cancer, the recommended dose is 150mg/day. Those engaged in strenuous labor, smokers, and patients recovering from injuries may require 200mg/day.

The daily vitamin C requirement for infants up to 3 years old is 25-30mg, for those aged 4-18 years old it is 30-40mg, and for adults it is an average of 45mg per day.

For pregnant women, the daily vitamin C requirement is 50mg, and for breastfeeding women, it is 70mg. To ensure the body has enough vitamin C, it is necessary to provide sufficient amounts in the diet every day.

If, for any reason, your diet doesn't provide enough vitamin C, you should find ways to supplement it, but avoid overconsumption. Exceeding the recommended dosage can be harmful to your body.

Many people, upon seeing a doctor's prescription for vitamin C supplements to boost immunity, buy them and take them daily instead of water. Women, in particular, overuse vitamin C, taking large amounts frequently because they believe it protects against ultraviolet rays, resulting in fairer, rosier skin and fewer wrinkles.

Some people even claim that intravenous injections of vitamin C or preparations containing "C" will beautify the skin. All forms of vitamin C misuse are very dangerous; there have been cases of death due to vitamin C injections.

Do not overuse skin creams, or even worse, inject vitamin C intravenously in the hope of "changing dark skin to light," as there have been serious consequences in medical history, including deaths from vitamin C injections.

Note that when taking vitamin C, you should avoid eating pork liver because vitamin C is a substance with an ethylene alcohol structure, which is easily oxidized and destroyed. When it comes into contact with trace metals (such as copper, iron, and other ions), oxidation accelerates even faster, especially with copper ions; even if trace amounts are present, copper ions oxidize more than 1,000 times faster. Liver is a substance with a high concentration of copper. 100g of pork liver contains 2.3mg of copper. If you eat pork liver and vitamin C together, they will both oxidize, rendering them ineffective.
