I've been on the Rich von K protocol for 10 days (exactly following the last version he wrote). Haven't noticed much, although I seem to be handling thiol foods better (I'm chelating mercury, & these have caused me big problems in 2012). No side-effects. The protocol's doses are low, I think, plus I am not on methyl B12 (he thought it best to start more gently, with hydroxocobalamin). So could I now consider either: 1. Switching to the methyl B12? or 2. Upping the dosages of the supps? Or both?
