It has been shown that the decomposition reaction takes place on a definite boundary between the undecomposed …

Calcium carbonate is not a substance of concern and fulfils the conditions set in point 5.1 of Annex II to Regulation (EC) No 1107/2009. It is therefore appropriate to renew the approval of calcium carbonate as a low-risk substance. Implementing Regulation (EU) No 540/2011 should therefore be amended accordingly.

A serum calcium concentration exceeding 2.6 mmol per liter (10.5 mg per 100 mL) is considered a hypercalcemic condition. Withholding additional administration of calcium and any other medications that may cause hypercalcemia usually resolves mild hypercalcemia in asymptomatic patients, when patient renal function is adequate. …
