Due to the above-mentioned reason, in the present study the erosive potential of the soft drinks was evaluated after their supplementation with CaGP, which theoretically could be a source both of calcium and phosphate. However, in the CaGP molecule, phosphate is covalently bound to glycerol and is not expected to be released from the formulation in vitro in the absence of phosphatases. Despite this, phosphate might have played a role on the reduction of the erosive capacity of the soft drink due to its buffering capacity, as can be inferred from the pH
