What Is In Leeks For Guinea Pigs

Leeks are rich in various nutrients, and that is why people like to eat them in different dishes. Here is a list of the nutrients that are found in this vegetable:

Vitamins: Leeks contain vitamins K and C, which are suitable for them because vitamin K helps with blood health and vitamin C prevents infections. Vitamin K promotes heart health and keeps the blood from clotting. Vitamin C keeps guinea pigs safe from infections and builds the immunity system.

Moreover, guinea pigs cannot synthesize vitamin C in the body, meaning these rodents require a dose of this vitamin daily. Pet parents must feed supplements if the food does not contain reasonable amounts of this vitamin.
