Vitamin C is a critical component of a guinea pig’s nutritional needs. In order to compensate for their inability to synthesize Vitamin C on their own, Guinea pigs require a supplement of Vitamin C in their diet. As a result, providing our guinea pigs with a diet high in Vitamin C is extremely important.An average guinea pig requires between 10 and 30 milligrams of Vitamin C per pound of body weight on a daily basis. In order to recover from illness or to avoid suffering from a Vitamin C deficiency, a guinea pig will require approximately 50mg of Vitamin C every day or as directed by a veterinarian.

Because the requirement for Vitamin C varies depending on the growth rate, age, and a variety of other factors, it is always a good idea to be on the safe side and supplement with a higher dose (30-50mg). In contrast to calcium, any excess vitamin C will be excreted by the guinea pigs through the urine system. As a result, it is advisable to give sick guinea pigs an extra dose of Vitamin C.

What is the reason that guinea pigs require vitamin C in their diet?

Our guinea pigs’ growth and development are dependent on their intake of vitamin C. The fact that it aids in the formation of collagen makes it a critical nutrient. Collagen is essential for the maintenance of blood vessel integrity, bone formation, and other functions.

Moreover, it aids in the regeneration of tissue in all parts of the body. As a result, it is an absolutely necessary vitamin for our guinea pigs.

What can I give my guinea pig to supplement its vitamin C intake?

We must provide our guinea pigs with a varied diet in order to meet their daily requirement for Vitamin C in their bodies. However, even though hay is the staple diet for guinea pigs, it does not contain a significant amount of Vitamin C. A wide variety of leafy vegetables, fruits, and pellets are therefore included in their diet to ensure that it is well-balanced.

Several leafy vegetables and pellets that have been fortified with vitamin C are available, and these can be a good source of this vitamin. Alternatively, if your guinea pig is suffering from vitamin C deficiency, there are a variety of other supplement medications that you can administer to him.

Is it possible for guinea pigs to die from a lack of vitamin C?

Yes, guinea pigs can die unexpectedly if they do not receive enough Vitamin C in their diet. In guinea pigs, a vitamin C deficiency can cause internal bleeding and organ malfunction, which can result in an uncertain death.

It is recommended to feed at least 20-30mg of Vitamin C per kilogram of body weight per day through a variety of nutrient-dense foods so that their bodies can develop and function properly.

Dealing with guinea pigs that are deficient in Vitamin C

Guinea pigs require vitamin C, which should never be found in their drinking water!

If your guinea pig exhibits any signs of Vitamin C deficiency, you must schedule an appointment with your veterinarian right away. Your veterinarian will be able to diagnose your guinea pig’s condition and determine the most appropriate treatment for it.

If the veterinarian determines that the symptoms your guinea pig is exhibiting are caused by a deficiency in Vitamin C, he or she may recommend that you supplement the diet with Vitamin C-fortified food as well as some other medical supplement to address the problem.

You should think about including some vitamin C-rich vegetables and fruits in your guinea pig’s regular diet. During this stage, consuming an excessive amount of vitamin C-rich foods will not be detrimental.

If your guinea pig is suffering from a severe lack of vitamin C, he or she may be reluctant to eat vitamin-rich food or even treats in order to avoid further suffering. In that case, you must use liquid vitamin C and administer it to your guinea pigs via a syringe to ensure that they receive enough.

It is possible to obtain the recommended dose of Vitamin C from your veterinarian and administer it to your pet for a couple of weeks until you notice signs of recovery.

If syringe feeding does not work, you may need to take your guinea pigs to the veterinarian on a regular basis to have the Vitamin C supplement injected into their bodies.

Stage of Recuperation

Once the treatment has begun, your guinea pig should begin to show signs of improvement within a week or two. Maintain close observation of your guinea pigs to determine whether or not the symptoms are subsiding and whether or not they are becoming more active.

If your guinea pig does not show any signs of recovery after a few days, contact your veterinarian so that he can adjust the vitamin C dosage accordingly. Once you have determined that your guinea pig is recovering, it is time to turn your attention to external wounds.

If your guinea pig is suffering from severe scurvy, you will notice some scabbed skin and bleeding wounds on his or her body. It is now necessary to clean the injury on a regular basis and, if necessary, to seek external medication from your veterinarian.

The majority of the time, once the wound’s Vitamin C requirements are met, the wound will heal on its own. It may be beneficial to have your guinea pig prescribed pain medication if you notice that he or she is suffering and in a great deal of pain, for example. Consult your veterinarian about the appropriate dosage and, if necessary, obtain one for your guinea pig.

Is it necessary to give guinea pigs vitamin C tablets?

No, it is not recommended to give your guinea pigs a Vitamin C tablet until and unless they are suffering from a Vitamin C deficiency in the first place.

In general, if you feed your guinea pigs a balanced diet that includes fruits, vegetables, and pellets high in Vitamin C, they are unlikely to suffer from a deficiency in Vitamin C.

You can, on the other hand, supplement their Vitamin C intake by giving them a quarter of a chewable Vitamin C tablet every day if they are suffering from a lack of it. Vitamin C tablets are typically available in 100mg dosages. As a result, your guinea pigs will receive nearly 25 mg of Vitamin C from a quarter feeding.

Quick Tips for feeding Vitamin C tablets to your guinea pigs:

  • Some guinea pigs are intrigued by the smell of the tablet and consume it, believing it to be a treat. Break the tablet to the appropriate size and place it in their cage. Alternatively, if your guinea pigs are accustomed to being fed by hand, you can hand-feed them the tablet.
  • Crush the tablet into a powdery texture and sandwich it between some green leafy vegetables that they enjoy eating. For instance, romaine lettuce, spinach, and so forth.
  • You can also make a groove in their favorite fruit, such as a grape, strawberry, or other similar fruit, and insert the crushed tablet into it.
  • If none of the above methods are successful, you may need to syringe feed the tablet by dissolving it in water and injecting it with a syringe as soon as it is mixed.

Is it safe for guinea pigs to consume human vitamin C tablets?

Yes, guinea pigs are capable of consuming a human Vitamin C tablet. You may need to feed it only partially depending on the size of the container it comes in. Also, make sure you get a vitamin C tablet rather than a multivitamin, as the latter will be ineffective for your guinea pigs’ health.


What amount of vitamin C should I give my guinea pig is up to you.

An average guinea pig requires between 10 and 30 milligrams of Vitamin C per pound of body weight per day, on average. The young and nursing guinea pig, on the other hand, may require as much as 40mg/day for every pound of their body weight. The requirements for guinea pigs may differ depending on the breed, size, and age of the animal.

You should always feed your guinea pigs a diet that is high in Vitamin C. When it comes to vegetables and fruits, guinea pigs are extremely picky. Consequently, continue experimenting to determine which foods are effective and which are ineffective so that you can provide them with a nutritious and well-balanced diet.

It is important to note that you should never add any Vitamin C supplements to their water. If guinea pigs don’t like the taste of water, they may not drink as much as they should. It has the potential to lead to starvation and death.
