What actionable step should a consumer take when considering any mineral powder from a geological source for internal use?

Answer

Seek certification of analysis, specifically looking for labeling like 'Food Grade' or data detailing heavy metal testing.

When dealing with mineral powders derived from geological extraction, the primary consumer concern shifts from the presence of calcium carbonate to the absence of harmful components. The recommended actionable tip for ensuring safety for internal consumption is to demand verification of quality. This verification should come in the form of a certification of analysis (COA). Consumers must actively look for specific classifications such as 'USP Grade' or 'Food Grade,' which imply a higher level of processing and quality control. Crucially, the analysis must include specific testing results for undesirable trace elements, such as lead or arsenic, ensuring that the calcium intake is not coupled with unwanted mineral baggage acquired during extraction.
