Recent work indicates the very real possibility of sources for interference in the metabolism of the potassium ion within the human body (potassium levels that are too low in the body may present medical difficulties such as heart failure, fatigue, muscular weakness and depression). This interference is based upon the detection of continuous and apparently artificial ELF (Extremely Low Frequency) propagation at 4Hz multiples. The fifth harmonic of this radiation, detected at 20Hz, corresponds to the cyclotronic frequency of the potassium ion in the mid latitude ranges of the globe. Readers are referred to a previous Carnicom article on this topic titled ’POTASSIUM INTERFERENCE IS EXPECTED’ (dated May 15, 2005), and to the work of Dr. Robert Becker for additional information on this subject. Upon further inquiry by Clifford Carnicom on the attempt to increase potassium levels in the diet has revealed some unexpected findings. It might be considered reasonable for an individual to seek out a potassium supplement, in addition to the investigation of changes in the diet. Such a search has been conducted by Carnicom...upon examining all potassium supplements at the local health food store, regardless of brand, Clifford soon noticed that no products were available that provided a level of potassium greater than 3% of the recommended daily allowance for potassium.
