Calcium Globionate is absorbed by the body as needed. It will not be over-absorbed and will not damage organs. It's great for treating MBD. You just have to administer orally.
I agree with most everything that has been said on this thread with the exception of the fact that you cannot overdo the calcium globionate.
Any oral calcium will not be overdone if the body is regulating its own D3 sythesis. Natural sunlight and/or the UVB bulbs. However, if supplementation is being given of the D3, (and many breeders recommend the rep-cal with D3 2-3 times a week when they are young and those that are pregnant) the body will not be able to turn off the negative feedback mechanism. More calcium will be absorbed putting the animal into hypercalcemia.
A number of cc's of calcium globionate in a baby veiled is way too much. The only reason you are getting away with that is that they are not being oversupplemented with D3, and the excess Calcium is passing right through the gut and getting excreted.
Those chams that have secondary nutritional hypeparathyroidism (a form of MBD) will respond to calcium supplementation to resolve their deficiencies, but not too much too fast, or you can go the other way...
Good luck,
