Guinea Pig Vitamin C Food List (Dosage, Serving Size & More)

It is a known fact that guinea pigs, unfortunately, can suffer from a vitamin C deficiency and without a proper daily dosage of this vitamin they can develop serious health problems. Therefore, it is highly important to feed your guinea pig with the right types of vitamin C rich foods or supplements because they cannot produce vitamin C by themselves.

So, what are the most recommended vitamin C rich foods for our guinea pigs? To make your life easier, we have compiled not only a guinea pig vitamin C food list but we also added the proper dosage and serving size for every food on the list.

Vitamin C can be found in nature in the form of fruits and vegetables but even when you are feeding your guinea pig with enough healthy foods, they can still suffer from vitamin C deficiency.

Supplements, in this case, play a vital role as they can instantly boost the vitamin C levels of your guinea pig, this is why we also made a list of the best vitamin C supplements you can buy on Amazon for guinea pigs.

When guinea pigs lack vitamin C, they can develop a disease known as scurvy. The symptoms for this disease are hair loss, bleeding, weakness, pain in the joints, and all-around feeling weak. In order to prevent this terrible disease, you have to treat your guinea pig with special care. There is also scientific research that shows how vitamin C deficiency impairs early brain development in guinea pigs.

Health Problems Caused by the Lack of Vitamin C – Scurvy

The main reason why guinea pigs can suffer from a vitamin C deficiency is that they cannot produce this vitamin by themselves. It is therefore important that they have a correct and balanced diet! Vitamin C deficiency can cause the following symptoms:

  • Swollen joints
  • Poor hair dullness (mainly dullness and fallout)
  • Sores on the lips or mouth
  • Diarrhea
  • Difficulty in moving
  • Little to no appetite
  • Lack of energy (lethargy)
  • Wounds take longer to heal

On average, a guinea pig requires from 10 to 30 mg/kg of the vitamin C each day in order to stay in good health. Guinea pigs that are deficient in vitamin C require a daily dose of up to 52 mg/kg.

We recommend that you feed your guinea pig with extra vitamin C in case they get sick. Still, if you are thinking of giving them more than 100 mg of vitamin C daily you should first consult with the veterinarian. Remember that excess amounts of vitamin C are released through urine and is not absorbed within the body.

Ways to Provide Your Guinea Pigs with Enough Vitamin C

There Are Three Ways to Give Your Guinea Pigs Vitamin C:

  • Fresh fruit and vegetables
  • Formulated pellets
  • Supplements in the form of drops or tablets

Tablets usually have 100 mg of vitamin C. This is not a problem as the tablet can be divided into quarters of 25 mg and administered directly to your guinea pig. Vitamin C drops can also be a valid alternative, as long as you follow the instructions on how to dose the drops (do not mix them with water). Also, do not purchase or use multi-vitamin supplements for your guinea pig.

Here Are Some Tips on How to Give Your Guinea Pig a Vitamin C Tablet:

  • Make sure you break the tablet so it can release its aroma. Place the piece near your guinea pig’s food so it also understands that it is edible. Otherwise, you can take off a smaller piece and offer it directly to your pet.
  • Crush the tablet, place it on a piece of lettuce, and roll it up.
  • Cut a groove within a carrot, apple or grape and insert the tablet inside.

Do You Prefer Vitamin C Drops Instead?

  • Do not mix vitamin C drops with water and leave it for too long because the bacteria can build up and make the water a health hazard.
  • You can, however, mix it with water and syringe feed your guinea pig as soon as possible. The vitamin C will not break down and your guinea pig will still be able to benefit from it.

List of Best Vitamin C Rich Foods for Guinea Pigs

Food Weight Vitamin C The amount required for 25 mg of vitamin C/day
Kale 70 g chopped (1 cup) 80 mg 1/3 cup or 5 tablespoons
Broccoli 90 g chopped (1 cup) 81 mg 1/3 cup or 5 tablespoons
Cauliflower 13 g (1 piece) 6 mg 4 pieces
Green pepper 150 g chopped (1 cup) 120 mg 4 tablespoons chopped
Papaya 145 g (1 cup) 87 mg 1/3 cup
Peas 60 mg (1 cup) 60 mg ½ cup
Cilantro 3 g (1 tablespoon) 10 mg 3 tablespoons


This list contains the most optimal foods for guinea pigs that have vitamin C. They may not have the highest percentage of this vitamin but the food on this list can be fed often. Fruits that are higher in the vitamin such as oranges and kiwis have high levels of acid and sugar and if fed often to your guinea pigs they can cause health problems. Cabbage, mustard spinach, and beetroot greens are also an option but they must be limited to once or twice a week because they are high in calcium. Too much calcium can lead to bladder or kidney stones.

Vitamin C Supplements vs Vitamin C Rich Food for Guinea Pigs

After reading all of this you may be asking yourself “Do I buy fruits and vegetables or opt for the supplements?”. Well, that depends mostly on you.

Fruits and vegetables are the natural and healthy source of all vitamins, fibers, and minerals. They can be purchased or grown at home. There is a large variety of food for your guinea pig to experiment on as well, maybe it prefers sweet over savory or vice versa.

On the other hand, fruits and vegetables, even if given in abundance, will not always give your guinea pig the right amount of nutrients, including the vitamin C. Therefore, there is still a considerable risk when feeding guinea pigs solely with plants and fruits. This is where vitamin C supplements can play an important role and are not to be underestimated. Whether in the form of tablets, drops or seeds, there should be a perfect fit for your guinea pig.

Drops may be beneficial but they can also make the water unappealing for your pet to drink. Use and follow the instructions with caution. Tablets are more feasible and don’t have considerable downfalls. Seeds may be your best bet as they are natural and can tempt the guinea pig into eating them. Plus, they encourage the pet’s natural feeding habits.

The real deal-breaker could be the cost involved in each option. You may want to introduce a balance between foods and supplements, just to be on the safe side. Better safe than sorry!

  • Are There Any Risks for Guinea Pigs from Taking Vitamin C Supplements?

This depends on you and how you dose or serve the vitamin C supplements to your guinea pig. By putting too many drops in the water you can discourage your pet from drinking, resulting not only in vitamin C deficiency but also dehydration. Tablets and seeds have high quantities of fibers and with the wrong dosage could actually harm your guinea pig and cause internal problems such as bloating and stomach pains. Watch out! With the right dosage, nothing can happen to your cute guinea pig pet.

Remember that guinea pigs are overall very active and playful if you notice your pet is always sleeping or hiding away this could indicate a health issue. Always check up on your guinea pig if you notice a new behavior!
