Is this what you have always used? If so this may be part of the issue. Exoterra does not put vitamin A in their multivitamin. They use beta carotene instead which has not been proven to be able to convert in their system to usable Vitamin A. Now it does have D3. With what your Vet is recommending with so much D3 intake she will be overdosed on D3 which can cause many other issues. When you overdose them on D3 they can start pulling calcium from their bones instead to try to balance it out and it can compromise organ function. Not to mention with a female that needs plain calcium without D3 for egg production this could cause some very serious issues along with full decline in health.Exoterra multivitamin and a calcium+d3 powder. The multivitamin a few times per week and the calcium+d3 could be used at nearly every feeding according to the vet.
I would use a plain calcium without D3 for all feedings and then replace your exoterra supplements and buy Repashy Calcium Plus LoD version. This is a multivitamin with vitamin A and D3 this would only be given 2 times a month say the 1st and the 15th.
