For the past year and one half, I have been offering my adult male gecko a cap full of Rep-Cal w/ D3 in his enclosure at all times.

Have I been incorrect in supplying him with the formula containing D3? Should I be using the calcium only powder? I am guessing that I would need to dust the mealworms and crickets with the D3 formula and leave pure calcium in the bottle cap if this is the case...

What do you all think?

You should only give calcium with D3 once a week. The dish in the tank should be calcium only (no D3). Also, dust the food once week with gecko vitamin powder. Hope this helps Fran

This is always a thing I never understood, supposedly vitamins and minerals will degrade each other if combined right? Well why do the same brands that preech this supply a mix combo of both?

I use a dish of calcium and I dust my feeders with vitamins for this reason.

I haven't done any research that has led me to validate the idea that some combinations of vitmains and minerals negate each other (at least not calcium and the vitamins included in products we use supplement our reptiles' diets) but I DO know now that vitamin D3 can be toxic at high doses (it can cause kidney and liver damage in humans). However, I am not sure what consititutes a "high dose."

I have changed my routine--I now keep a supply of pure calcium in the enclosure and dust the food twice a week with calcium containing D3.
