Effects Of Overdose Of Vitamin-C


Vitamin C is considered an essential nutrient for the proper functioning of our body: it promotes the production of collagen, increases our defenses and prevents the appearance of some diseases such as anemia, among other benefits. For all this, it is necessary that we consume daily foods that contain a good content of vitamin C.tablets

However, it is important that we take the correct dose of vitamin C since like its deficiency can bring some health problems, the excess of this vitamin too.

What is vitamin C for?

Vitamin C, also known as ascorbic acid , is an essential nutrient for our body, as it collaborates in some of its functions. Among the benefits of vitamin C for health we find the following:

  • Produces collagen : ascorbic acid is necessary for the production of collagen, a protein that is responsible for accelerating the healing process of the skin in the case of wounds and rashes.
  • Prevents premature aging : it is a nutrient with a high content of antioxidants, which protects us from the formation of free radicals, which are the main causes of the oxidation of skin cells. In this way, it prevents premature aging of the skin.
  • It helps to absorb minerals : vitamin C is an essential nutrient for the correct absorption of minerals such as iron, especially if the sources are of vegetable origin.
  • Improves the immune system : ascorbic acid also has properties that improve the functioning of the immune system, as it increases the defenses of our body.

Consequences of excess vitamin C – common diseases

The excess of vitamin C is not a phenomenon that usually occurs because it is a water-soluble nutrient, that is, it does not remain accumulated in the body, since it is expelled through the urine . Therefore, its excess is usually caused due to an intake of ascorbic acid that considerably exceeds the appropriate daily dose.

Below, we tell you some of the problems and diseases caused by the excess of vitamin C in the body:

Gastrointestinal disorders

Excessive daily consumption of vitamin C can cause different problems in the gastrointestinal system. Among the most common digestive problems that occur when we have consumed a very concentrated dose of ascorbic acid are: diarrhea, discomfort and stomach cramps and nausea , among others.

In addition, continued excessive consumption can cause other problems such as an alteration in our intestinal flora.


Another disease caused by an excess of vitamin C is hyperoxaluria. This condition, which affects especially the infant population , consists of the accumulation of calcium oxalate in the urine, a compound that is formed when vitamin C is oxidized (oxalate) and then binds to calcium (calcium oxalate).

The accumulation of this substance in the body can lead to more serious problems, such as the formation of kidney stones in the kidney.


Another disease caused by the excessive consumption of ascorbic acid is hemochromatosis. This condition occurs when more iron accumulates than normal in the body, which can damage your tissues .

In addition, you may have other symptoms such as abdominal pain, joint pain, fatigue and weight loss , among others.

Other health problems

In addition to the above diseases, excess vitamin C can cause some of the following problems:

  • Gout attacks : high consumption of ascorbic acid in cases where the person has high uric acid levels can aggravate gout attacks.
  • Scurvy : if a person eats very concentrated doses of this vitamin and suddenly stops taking it, he may suffer from scurvy.
  • Increase in diuresis : a high concentration of this nutrient can decrease the effects of some treatments, because diuresis is increased.
