Swiss chard is an excellent source of Vitamin A and Vitamin K. These Vitamins are essential for the proper functioning of the body.

While Vitamin A is needed for the proper operation of the liver, kidney, and heart.

Vitamin K is essential for quick recovery of injuries and preventing excessive bleeding from an injury.

Chard is also a great source of Vitamin C, which is another crucial vitamin for the body. Vitamin C is needed for maintaining a robust immune system, prevention of diseases, and other vital functions of the body.

Apart from all these Vitamins, chard also provides calcium, phosphorus, iron, magnesium, carotene, polyphenols, etc. that are needed by the body.

So, now that you know what the nutrients present in chard is let us learn about which of them are good and which are bad for our guinea pigs.

Is chard bad for guinea pigs?

No, chard is good for guinea pigs until fed in moderation. As I always say, “Anything in excess is bad for health,” the same applies to guinea pigs as well.

Leafy vegetables like spinach, beet greens and chard are excellent sources of nutrients for our guinea pigs. However, these greens are rich in oxalic acids as well, and excessive feeding of the same is terrible for our guinea pig’s health.

As per the studies, a guinea pig should not have more than 50 grams of oxalic acid daily. That means their diet should be well-balanced, and the oxalic acid should not go beyond that limit.

Let us look at some common health issues that guinea pigs can have if you overfeed them chard:

  • Stone formation: Bladder stones are one of the most commonly diagnosed diseases among guinea pigs. These stones are mostly formed due to calcium binding with oxalate acid in their bodies. Thus, overfeeding a diet rich in calcium and oxalate acid is a terrible choice you can make.
  • Diarrhea: Diarrhea is also prevalent in guinea pigs & sometimes it can be fatal for your guinea pig’s life as well. Guinea pigs have a sensitive digestive system, and overfeeding any food can set it off balance leading to severe diarrhea.
  • Renal system failure: Guinea pigs can only take a limited amount of oxalic acid at once. If you overfeed oxalic acid to your guinea pigs, then they can suffer from renal failure, sometimes leading to death. Thus, make sure you only feed chard in small quantities to your guinea pigs.

Chard is good for humans as well as guinea pigs. However, overfeeding the same can lead to a lot of health issues in guinea pigs. Thus, you must ensure that you are feeding them the right diet.

Benefits of chard for guinea pig’s health?


Swiss chard or even chard, in general, is a great leafy vegetable for your guinea pigs. If we feed chard in moderation, then guinea pigs can have a lot of health benefits from the same. Here are some to begin with:

  • Prevention of scurvy: Chard contains a lot of Vitamin C in it. Guinea pigs need 30mg of vitamin c daily to prevent diseases like scurvy. Thus, adding vegetables like chard, cilantro, or even kale can help reach that mark easily. It would be best if you focused on providing guinea pigs with a diet rich in Vitamin C as they cannot produce vitamin c on their own.
  • Smooth and healthy coat: Chard is an excellent source of beta carotene, which helps the body in absorbing other nutrients. It also helps guinea pigs in maintaining a smooth and healthy coat. Thus, I would recommend adding some fresh chard into your guinea pig’s diet.
  • Quick recovery of wounds: Vitamin K and Vitamin A can be found in abundance in chard. Providing your guinea pigs with a diet rich in these vitamins can improve their immune system and also help in quick recovery of wounds or any other disease they may have.
  • Improving eyesight: Guinea pigs have poor vision, and it keeps getting worse as they age up. Throwing some food rich in Vitamin A can help guinea pigs in keeping up with good eyesight. At least it can slow down the process of degeneration, which is good for our guinea pigs.

There are countless more benefits of chard for guinea pigs. However, the fact is your guinea pigs can only take the benefits if you feed it in the right quantity and at the proper schedule. So, let us learn more about how often you should feed them swiss chard and how much?
