Guinea pigs share a unique quality with human beings: the inability to synthesize (create) Vitamin C for their bodies. Because this is true, Vitamin C must be supplied to guinea pigs through food or supplement intake. Guinea pigs failing to receive adequate levels of Vitamin C will develop the disease, that in people, is known as scurvy.
What causes scurvy?
In human history, scurvy was common among sailors who traveled long distances without access to fruits and vegetables containing Vitamin C. In 1747, James Lind, a Scotsman, discovered that sailors suffering from scurvy were cured by eating oranges and limes. Science has since shown that it was the Vitamin C in the fruit that made the difference. Similarly, Guinea Pigs need vitamin C supplemented in their diet to prevent this disease.
Symptoms of scurvy in your guinea pig
Indicators of a Vitamin C deficiency in guinea pigs include loss of appetite, bleeding from the gums, joint stiffness, general lethargy, weight loss, poor tooth development and nasal discharge.
Avoiding Vitamin C deficiency
To help guinea pigs avoid a deficiency, premium food manufacturers often add Vitamin C to food pellets at the time of manufacture. Under normal conditions the Vitamin C in food pellets remains active for up to three months. Under adverse conditions - too much heat or humidity for example - Vitamin C may lose its effectiveness in much less time. Buying food pellets one month at a time and properly rotating fresh food into the guinea pig's diet will help ensure that the Vitamin C in the diet is at adequate levels.
Foods high in Vitamin C
Feeding a guinea pig a diet with Vitamin C rich fresh fruits and vegetables is also important. The following fruits and vegetables contain high levels of Vitamin C:
