What supplements/vitamins are you giving your toddlers?

Personally I don't like to give supplements too much for my kids because it may be too much for their liver. I prefer to have a balanced diet for them, that is still the best way to have all the necessary nutrients. However cod liver oil is something which I will give. In my opinion multi vitamins or vitamin c tablets are unnecessary if the kids have a balanced diet, active lifestyle and sufficient exposure in the sun. A lot of multivitamins and supplements have sugar contents in them to make it more palatable for the kids which I don't like .
