What Are The Best Vitamin C Sources For Dogs?

Vitamin C is a vital organic compound that is necessary for maintaining a healthy life for your dog.

Even though vitamin C is naturally produced by your dog’s body, it is always great to give them a bit extra since it can benefit their health and immune system.

What is Vitamin C and Why it is Important for Dogs?

Vitamin C is a natural nutrient found in your dog’s body and it does not only provide the necessary nutrients to improve muscles functionality, collagen, and cartilage but also works as an antioxidant to protect the body from free radicals.

Free radicals are molecules that can be found in the body with negative characteristics that are potentially harmful and can cause damage to DNA codes, which results in health problems down the line.

Since Vitamin C is a water-soluble vitamin, it doesn’t require fat cells for storage or absorption. Instead, it dissolves in water and can be easily absorbed by cells in the body.

Vitamin C comes with many benefits for your dog, but unlike humans, dogs don’t require a Vitamin C boost in order to reach their daily dose. As we mentioned, dogs produce vitamin C on their own and they use raw ingredients from their diet to synthesize vitamin C in their liver.
