As the saying goes: “There must be a degree in everything.” Vitamin C tablets are the same, too much good food will also cause problems.

What happens if I eat too much vitamin C?
If you take too much vitamin C, it may cause some effects on your body. The most common is digestive system disorders, because vitamin c is an acidic substance. If you take 1 to 4g of vitamin c daily, it will cause absorption disorders of the gastrointestinal tract, which will cause It can cause acid reflux, heartburn, nausea, vomiting, etc. in the gastrointestinal tract. In severe cases, the stool may not be formed, or the mucus pus bloody stools, loose stools, etc.

- Kidney stones: A case study from the International Journal of Kidneys reported that a woman who took 4 grams or more of vitamin C a day developed kidney stones after 4 months. This is because vitamin c is an acidic substance, which can cause the pH value of urine to decrease after being taken in large amounts, and the oxalate and urate in urine are significantly increased, and kidney stones are easily formed.
- Hemolysis or coagulation: If vitamin C is taken orally for 2.5 to 5 g at a time, or even higher, it may cause a large number of red blood cells to rupture, causing serious phenomena such as hemolysis; if intravenous injection of large doses of vitamin C can cause venous thrombosis, causing intravascular Hemolysis or coagulation, severe cases can be life-threatening. It can also cause allergies, local pain during injection or tissue necrosis during injection.
- Scurvy: If vitamin C is always taken in large amounts, vitamin C withdrawal will occur once the vitamin C is suddenly stopped, and the withdrawal reaction will cause people to suffer from scurvy. For example: pregnant women taking vitamin C in large quantities will make the fetus dependent on the drug. After birth, if they do not take a lot of vitamin C to the baby, scurvy can occur, such as lack of energy, bleeding gums, bleeding under the skin, There are even symptoms of gastrointestinal tract and urinary tract bleeding.
- Liver and kidney failure: Vitamin C supplementation will also increase the burden and load on the liver and kidneys, because vitamin C is mainly digested by the liver and excreted by the kidneys. If excessive vitamin C supplementation will lead to increased work of the liver, the workload of the kidney’s glomeruli and renal tubules will also increase, and long-term vitamin supplementation will cause chronic liver and kidney dysfunction.
In summary, although vitamin C is a nutrient element required by the human body, the supplementation of any nutrients must be moderate. Once excessive, it will cause physical burden, gastrointestinal adverse reactions, scurvy, kidney stones, hemolysis or blood coagulation, Negative effects such as liver and kidney failure can also threaten life and health in severe cases.
