What nutrients does my guinea pig need?
Vitamin C. Vitamin C. Vitamin C. Get the idea? This may be the most important thing that you as a guinea pig owner need to know. Guinea pigs cannot manufacture or store vitamin C and are very susceptible to scurvy. Anywhere from 15-30mg per day are required depending on whether you have an adult, pregnant or nursing guinea pig. It is important to learn as much as you can about vitamin C supplements and your guinea pig.
Naturally, guinea pigs need a whole host of nutrients for proper health (vitamins, minerals, proteins, etc.) just as any animal needs. A correct amount of prepared pellets mixed with fresh food containing vitamin C will give your guinea pig a balanced diet. Vitamin C breaks down rapidly in the prepared pellets, it must be added back in your guinea pigs diet with fresh foods or supplements in his food or water.
