I have reviewed some information on B12 supplementation that can be found it relates to autism. I found it to be very helpful so I thought I would share that. Not that any of us need more information to review.
I with some study apply the principle of Gestalt psychologist Kurt Koffka: "The whole is other than the sum of the parts." I use this principle to develop my ever evolving understanding of B12 deficiency and my self treatment.
I use the checkbox/algorithm principle when applicable. I do not expect that being applicable to my B12 deficiency in the immediate future and no reason to believe it ever will be. I understand that is the medical model and that model in practice does not lend itself to designing treatment by symptoms/results.
