In my personal opinion, you are better off simply using Rep-cal than the supplement you mentioned. Rep-cal is an organic calcium based compound, produced by grinding oyster shells into a fine powder. I believe it is far easier for the tortoises to absorb and utilize the calcium in this form than from a sterile powder of pure calcium. This does not even address the question of the magnesium you mentioned. I have no idea what a tortoise's magnesium requirements may be (if any), but if not the same as what a human needs, the ratio of the two will be skewed for the tortoise in all likelihood. Oyster shells being a bonelike material are far more likely to have the primary and trace elements necessary for tortoise shell growth (and in the proper ratios to form healthy bone) than a powder of pure calcium or the calcium and magnesium powders if you used both of them from those capsules (I wasn't sure if you intended to use one or both of the powders in the capsules from your post).
