I keep seeing stuff on here about overdosing on D3? It seems like a rabbit hole....does anyone know what the safe amounts are to give my 3-4 month old dragons? I have Tetrafauna Reptocal with D3 and the National Geographic reptile multivitamin powder. Should I be dusting 5 times a week? Less? More? I have been using the calcium 5 times a week and the multivitamin twice a week. After all this reading I'm afraid that's not correct.
