Dusting questions

[Juce23]

So I've read in a few places about dusting your insects with a calcium/vitamin mix.. I'm not a scientist but basically it said that it was not a good way to do it, because the calcium was "cancelled out" when used In tandem with viatamins and that they should be offered separately .. I use Repashy cal plus that had calcium and essential vitamins and nutrients.. I know Repashy is a respected name and was wondering if it was okay to still use it.. My dragon is almost 12 months old and is about as healthy as he can be from what I see.. He gets daily salad consisting of collards or turnip greens, endive , green beans and squash.. And is fed crickets dusted with the Repashy twice a day.. I only dust the crickets once a day of the two Daily feedings and only 5 days a week ( 2 days of no dusting)
