Electrolyte balance

There is also potassium in the leaves, which helps with the proper balance of electrolytes in the guinea pigs’ bodies.

With the help of potassium, the guinea pigs will improve the state of salts in relation to the water in their body.

If guinea pigs do not have sufficient amounts of potassium they will have the following signs of problems:

  • dizziness

  • fatigue
  • low blood pressure

Tooth growth

When guinea pigs’ teeth grow they feel a certain level of pain.

But by eating leaves they get vitamin C which helps to reduce such pain and encourage the growth of teeth.

So give them leaves and spare the guinea pigs from unnecessary pain when they grow their ever-growing teeth.

Cancer protection

If guinea pigs eat moderate amounts of leaves they will have better protection against cancer.

There are many antioxidants in the leaves, such as vitamin A, which is a very known antioxidant.
