Pampered Pets: Should you give your guinea pig vitamin C? – Express.co.uk
When fed on fresh hay, alongside good quality guinea pig pellets, deficiency is unlikely. In addition spinach, broccoli, dandelion leaves, peppers and tomato fed in small quantities all offer high levels of vitamin C.
With a good diet, supplementation is not necessary, unless the guinea pig stops eating, in which case a veterinary examination is required.
As you have only recently acquired them, I would advise a check-up anyway which would include a physical examination, with particular attention paid to the teeth and general advice on diet.
