I think most of the ratty members around here use Viral Guard Junior syrup now since this thread was started too, or at least that's what has become the most popular vitamin supplement of choice. Especially since it has some nice ingredients to help fight off sickness too, besides being a multivitamin
It's also available from most pharmacies, Clicks, etc. The following is based on an average adult +-300g rat, so adjust accordingly for smaller or larger furkids:
0.1ml a day per rat for two weeks, then one week break
The break is because it has echinacea, so this helps to prevents any resistance buildup to it's effectiveness, a common side-effect.
Booster dosage - for sick ratties:
0.2ml per rat per day
