Questions about calcium malates
Is calcium malate harmful?
The JECFA database (the FAO/WHO expert committee) records an evaluation from 1979: an ADI of “not specified” (no numerical ADI is needed) for calcium DL-malate, included in the group ADI for DL-malic acid and its sodium, potassium and calcium salts.
Is DL-calcium malate permitted in Vietnam?
