Vitamin C?

[bpdfs]

What is the best source of Vitamin C I can give my boy?

 

[Bailey]

A good guinea pig food should have Vitamin C added to it, if you're in the UK there's Supreme Science Selective, Burgess Excel, Oxbow Cavy Cuisine.
Plenty of fresh vegetables too.

If you feed a good quality diet there's no need to add a supplement to the water.
