Vitamin C is an important nutrient for the health of dogs. It is involved in many metabolic processes, strengthens the immune system and protects against oxidative stress. But how much vitamin C does your dog need? And are there risks associated with too high or too low an intake? In this article, you'll find out everything you need to know about vitamin C for dogs.

What is vitamin C?

Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that is found in many plant and animal foods. It is primarily known for its antioxidant effect, i.e. it intercepts free radicals that can cause cell damage. Vitamin C is also involved in the formation of collagen, an important structural protein for skin, bones, tendons and cartilage. Vitamin C also supports the function of white blood cells, which are responsible for the defense against infections.

How much vitamin C does my dog need?

Unlike humans, dogs can produce vitamin C themselves in their liver. This means that they normally have no additional need for vitamin C as long as they receive a balanced diet. The recommended daily dose for dogs is around 40 mg per kilogram of body weight. However, this amount can vary depending on age, health status and stress factors.

When can an additional dose of vitamin C be useful?

There are some situations in which an additional dose of vitamin C can be useful for dogs. For example:

  • In older dogs whose ability to synthesize vitamin C decreases
  • In dogs with chronic diseases such as arthritis, diabetes or renal insufficiency
  • For dogs with acute infections or injuries
  • Dogs that are under a lot of stress, for example due to traveling, moving or training
  • For dogs undergoing a change of diet or suffering from malnutrition

In these cases, an additional dose of vitamin C can promote the health and well-being of the dog and speed up recovery. However, the dosage should always be discussed with a vet to avoid overdosing.

Are there risks associated with too high or too low an intake of vitamin C?

Too high an intake of vitamin C can lead to diarrhea, vomiting, stomach problems or kidney stones. A long-term overdose can also lead to a reduced absorption of other nutrients such as copper or iron. You should therefore always ensure that your dog does not receive more than the recommended daily dose.

Too low an intake of vitamin C can lead to scurvy, a disease characterized by bleeding, inflammation of the gums, joint pain and weakness. However, this is very rare as dogs can normally produce enough vitamin C themselves.

Which foods contain vitamin C?

Vitamin C is found in many plant and animal foods. The best sources include:

  • Fresh fruit such as oranges, strawberries or kiwis
  • Fresh vegetables such as broccoli, peppers or Brussels sprouts
  • Offal such as liver or kidney
  • Meat such as beef or poultry

These foods can be given as a supplement to the normal food or as part of a home-prepared meal. However, care should be taken not to overheat the food, as otherwise some of the vitamin C content will be lost.

Vitamin C is an important nutrient for the health of dogs. It has many positive effects on the immune system, skin, bones and cells. Dogs can normally produce vitamin C themselves, but in some situations it may be useful to give them extra. However, the correct dosage should always be observed and a vet should be consulted to avoid side effects. Vitamin C is found in many foods that can be used as healthy snacks or as part of a balanced diet.
