Can excess vitamin C harm immunity?

It is often said that the better is the enemy of the good. When it comes to supplementation, the effects of under-supplying certain ingredients are just as dangerous as overdoing it. Can excess vitamin C harm immunity? How can you tell if ascorbic acid is being supplied in too large quantities?

The role of vitamin C for the human body

Vitamin C has an incredibly important function for human health. The substance called ascorbic acid is primarily an important element for the proper functioning of immunity. Therefore, its additional supplementation is recommended during the season of lowered immunity in autumn and winter, among others.


The antioxidant properties of vitamin C are particularly important in protecting cells from free radicals and the adverse effects of oxidative stress. Especially since ascorbic acid supports the regeneration of vitamin E, which has strong antioxidant properties.


The role of vitamin C is not just limited to immunity. Ascorbic acid has a number of other important functions in the body. Among these are:

  • help reduce feelings of fatigue and tiredness
  • maintenance of normal energy metabolism
  • support of iron assimilation from food, reducing the risk of iron deficiency
  • influencing the correct production of collagen - a protein that supports the correct function of bones, cartilage, skin, teeth, mucous membranes and blood vessel walls

How can excess vitamin C harm immunity?

The consumption of too many products rich in vitamin C - both foodstuffs and dietary supplements - can harm the body. Excess of each ingredient sooner or later turns out to be the cause of many irregularities. The main consequences of excessive amounts of ascorbic acid are nausea, skin changes in the form of rashes and troublesome diarrhoea. High levels of vitamin C may also lead to the development of kidney stones. This may be the result of excessive excretion of uric acid and oxalates from the body, which is a common result of ascorbic acid overdose.
