Guinea pigs are small pets that many people love. They are gentle and fun to watch. But to keep them healthy, you must feed them well. One very important thing for guinea pigs is Vitamin C. They cannot make this vitamin by themselves. So, you must give it to them through their food.
Why Do Guinea Pigs Need Vitamin C?
Vitamin C helps guinea pigs in many ways. It keeps their immune system strong. This means they do not get sick easily. It also helps their skin and fur stay healthy. If they do not get enough Vitamin C, they can get sick with a disease called scurvy. Scurvy makes them weak and can cause pain in their joints.
Because guinea pigs cannot make Vitamin C in their bodies, they need it every day from food. This is very different from humans and some other animals. So, feeding them food with Vitamin C is very important.

Best Foods With Vitamin C For Guinea Pigs
There are many foods that have Vitamin C. Some are fresh fruits and vegetables. Others are special pellets made for guinea pigs. Here are some good options:
| Food | Vitamin C Content (mg per 100g) | Notes |

Fresh Vegetables Are Very Important
Guinea pigs love fresh vegetables. They help provide Vitamin C naturally. Always wash vegetables before giving them. Remove any bad or soft parts. Cut into small pieces so your pet can eat easily.
Try to give different types of vegetables. This keeps their diet balanced. Do not feed only one kind every day. Variety is good for health.
Fruits Can Be a Sweet Treat
Fruits have Vitamin C too. But fruits have sugar. Too much sugar can hurt guinea pigs. So, give fruits only once or twice a week. Small amounts are enough. Good fruit choices are strawberries, oranges, and kiwi.
Guinea Pig Pellets With Vitamin C
Pellets are dry food made for guinea pigs. Many brands add Vitamin C to their pellets. This helps make sure your pet gets enough. Always choose pellets that say “with Vitamin C” on the package.
Do not give pellets only. Guinea pigs need fresh foods too. Pellets are part of a balanced diet, not the whole diet.
