Yep, I do too. Pretty much all of the multivitamin supplements around contain at least some D3 but I can't imagine the frogs getting enough to cause hypervitaminosis and the other vitamins are nice to have I definitely wouldn't rely on supplements to get adequate amounts of any vitamin let alone D3 though, much better to concentrate on a varied, well gut loaded diet and UVB and use supplements as a safety net. The problem in some circles is that a culture of feeding (usually one) easy to obtain feeder insect and throwing powder at it has developed. To me, that's a bit like giving a human a multivitamin pill and nothing but cheese sandwiches. You wouldn't die, but your health wouldn't exactly be optimum either.
