What essential characteristic of mined limestone powder dictates its suitability classification, such as Industrial Grade versus Food Grade?

Answer

The grade defines its suitability and potential health impact due to contaminants like silica or iron oxides.

The term 'limestone powder' is highly variable because the material can be processed for vastly different applications, necessitating a classification known as 'grade.' This grading system is essential because it reflects the safety profile derived from the source material's purification level. Industrial grade limestone, used in bulk applications like construction aggregate, often contains various trace elements—such as silica or iron oxides—that are inert or acceptable for environmental/structural use. However, these same trace elements can transform the material into a genuine hazard if consumed orally or inhaled chronically, meaning the grade is the determining factor separating safe supplement material from industrial byproduct.
