Monoamine precursors (contained in EM-BALANCE) besides being converted to tyrosine, can be converted to phenlyethylamine (PEA). This phenlyethylamine is an endogenous stimulatory or anti-depressive substance. As we age the body produces less PEA. Low urinary PEA levels are found in stressed and depressed individuals. The ingredients in EM-BALANCE are formulated to increase urinary PEA output and central nervous system PEA concentrations.
