Document Summary

Essential minerals are classifies as macro (major) or micro (trace) elements based on their abundance in body tissues and, therefore, daily requirements. Trace elements are present in body tissues at concentrations. Enzyme activation (most essential minerals catalyze one or greater cell reactions.
