Vitamin C




Vitamin C is of utmost importance to guinea pigs, as they are unable to manufacture their own (much like humans). Without enough vitamin C in their diets, guinea pigs can become very ill with scurvy. The amount of vitamin C required varies somewhat depending on the reference source used, but most guinea pigs probably need about 10-30 mg/day. Pregnant, nursing, young and ill guinea pigs need more.
If you feed a good selection of vegetables high in vitamin C along with a good, fresh guinea pig pellet, you can probably meet the vitamin C needs of the average guinea pig. Many guinea pig pellets have vitamin C added but unfortunately vitamin C is quite unstable and will degrade over time. Keeping the pellets in a cool dark place helps preserve the vitamin C. You can also get pellets with a stabilized form of vitamin C. The best way to supplement with additional vitamin C is to use vitamin C tablets. You can buy vitamin C tablets specifically for guinea pigs (e.g. Oxbow's GTN-50C), or buy human chewable 100 mg tablets (note: make sure you are getting just vitamin C rather than a multivitamin formula). A quarter of a 100 mg tablet daily is a recommended dose for most adult guinea pigs. The guinea pig tablets are 50 mg, but since vitamin C is a water soluble vitamin, small excesses over that daily requirement are easily excreted. Many guinea pigs will take the tablets like a treat and eat them, or they can be crushed and sprinkled on vegetables or pellets.
