Russ, tingling sensations ringing of the ears, and brain fog are all often caused by a vitamin B12 deficiency.
I understand what you're saying but just for clarity...
These symptoms are all caused -- at the root -- by mercury. It just happens that poor mercury excretors often have trouble methylating B-12 and therefore don't produce much glutathione (via the homocysteine-methionine pathway), hence they have poor mercury excretion. Hence we have a symptomatic association between B-12 deficiency and these symptoms.
No big surprise then that most autistic kids have trouble methylating B-12; They don't produce much glutathione and are -- therefore -- poor mercury excretors.
Raising B-12 only helps if the person is capable of utilizing methylating B-12. Better would be methycobalamine -- pre-methylated B-12. This helps in the utilization of homocysteine (lowering levels) and increasing glutathione production.
Unfortunately, B-12 also contributes to the methylation of mercury.
So, which evil do we choose?
It would be nice if we could all just work together to stop our governments from continuing policies and programs that promote mercury exposure (chemtrails, amalgam fillings, vaccines, tattoos, coal-burning power plants, etc.)
