Also known as: Ascorbic acid

Generally non-indispensable in dogs and cats, it is important to provide vitamin C in the food when the animal’s liver cannot produce enough. It helps prevent or treat diseases related to ageing, cell stress induced by physical effort and joint degeneration (arthritis)…

A little background information

While scurvy – vitamin C deficiency – has been known since the dawn of time in humans (sailors consumed lemons to prevent it), ascorbic acid is not an essential vitamin in the strict sense of the word in dogs and cats, which can synthesise it in normal conditions.

Its role in the body

Ascorbic acid is responsible for various vital bodily functions, such as:

  • neutralisation of free radicals (anti-oxidative stress effect): vitamin C permits the regeneration of vitamin E, a powerful natural antioxidant itself;
  • metabolism of iron;
  • selected anti-infection immune reactions.

Natural sources

Vitamin C is very common in nature and all vegetables contain it, especially citrus fruits (lemons, oranges), berries (blackcurrant), kiwis and strawberries. In dogs and cats vitamin C is synthesised in the liver from glucose.
