Too much vitamin C

Too much vitamin C can be harmful to your health. But when are you taking too much of this nutrient? What are the associated symptoms? And what causes them? This article discusses various topics and answers questions related to this.

Too much vitamin C

Taking too much vitamin C is rare, as it's a water-soluble vitamin. This means the vitamin dissolves in water, and any excess is not absorbed by the body as is the case with fat-soluble vitamins. Consequently, the body excretes the excess vitamin through urine. However, taking too much vitamin C for a long period of time can put a strain on the kidneys.

Symptoms of too much vitamin C

Several symptoms can occur with a prolonged excess of more than 2000 mg of vitamin C per day. Again, this only occurs in exceptional cases. The most common symptoms of too much vitamin C are:

  • Suffering from nausea
  • Suffering from diarrhea
  • If you have a predisposition to kidney stones, you are more likely to develop kidney stones
  • A deficiency of the G6PD enzyme can lead to a blood disorder. It is therefore advisable to avoid high doses of vitamin C.

Causes of too much vitamin C

Besides the various symptoms of too much of the nutrient, the cause is solely related to long-term intake of too much vitamin C. This involves using a supplement in combination with a diet rich in vitamin C.


How much vitamin C per day?

To avoid consuming too much vitamin C per day, it's important not to exceed the recommended daily intake of this nutrient. The maximum daily intake of vitamin C is 2000 mg. This intake is achieved through a combination of diet and supplements. Because 85% of the Dutch population doesn't consume enough fruits and vegetables, a deficiency is much more common than a surplus.
