Common questions about vitamin c
Is Vitamin C good for dogs?
Yes, we grade it as a good ingredient: recognisable and nutritionally useful, so it lifts a product’s score. Bear in mind that no single ingredient decides quality; the whole recipe and its balance matter more.
Why is vitamin C added to dog food?
Vitamin C, also labelled as ascorbic acid, is sometimes added to dog food as an antioxidant and to help stabilise other nutrients. Dogs can produce their own vitamin C, so it is usually included as a supplementary ingredient rather than an essential dietary addition.
Is vitamin C safe for dogs?
Vitamin C is generally recognised as safe in the small amounts used in commercial dog foods. Some dogs may be sensitive to it, particularly those prone to urinary issues, so speak to your vet if you have concerns.
