The issue isn't shortage but charge, no one is ever short Lithium. Oxidation occurs instantly if not paired with histadine. All in the links I posted already:
A freshly cut chunk of lithium is silvery, but tarnishes in a minute or so in air to give a grey surface. Its chemistry is dominated by its tendency to lose an electron to form Li+
The rest of the issues are already shown by Drug interaction. Remove Nickel and supplement L-Carnosine and you will never be Lithium deficient.
Li+ is not a cure for BioW Encephalitis nor Borna Disease, it also does not fix the lack of methylation to SAMe or Gaba and does nothing for Hg toxicity of the brain.
