You know, there is so much research in herpetology now (thank goodness!). We're finding out that iguanas cannot absorb D3 supplements and oversupplementation taxes their kidneys. UV Lights are so important to their overall health. I've read a study that showed that dietary D3 and exposure to sunlight demonstrated equal blood levels of previtamin D in monitors. I've heard stories of people of who do not use UV lighting on their beardies and supplement instead. I must say that the Reptiles mag article made me wonder 1)how much UV these lizards are actually receiving in captivity 2)if I need to go ahead and invest in a good UV meter.

Anyway, I don't pass judgement on others' husbandry because we all have to gather info and make our own decision. In the past year, I've decided to supplement my beardies more than I used to, but I still use UV lights. Like you, Paradon, I think it stimulates a natural appetite and photoperiod along with the vit D3 benefits.
