I use almost daily this product:

each drop has 6mg vit C. I give the piggies 2 drops (=12mg). Just a little supplement. A bottle costs 5-6€ and lasts 1 month (3 piggies)
In UK you have this supplement which is even cheaper

here the dosage is different... you have to calculate it.
Drops can be diluited in 3 drops of water or something else (I use pure cranberry juice+water+vit C). Then you will use a syringe... Vit C must be stored in dark and far from the air. hence, when you mix the drops you have to give them immediately.
The piggies will jump and climb on you... the taste is very good. There is no difficulty at all. (maybe only the first day when they don't know the taste...)
