Compositions are shown having high ORAC scores correlating with antioxidant capabilities. On one surface of the first circuit board, there are flash memories and a controller. Further, the RFID tag can be formed with a second substrate that can have any number of components, for example a strap, a processor, a blade and a coupling mechanism mounted thereon. Then, changes in the nominal calibration characteristics induced by the living tissue are calculated and a subject-specific calibration is formed by correcting the nominal calibration with the changes.
