I would like to discuss this matter of schizophrenia and bipolar disorder. If we jump into our way-back machine and read up on the studies of liver extract concentrate, before b12 was misidentified for a Nobel Prize, we will see some never duplicated results. Based on what I read in historical articles, back in the 70s, the studies carried out were done in the mental institutions just as earlier studies for b-vitamin deficiencies were done. Women hospitalized for post partum depression (that is severe) were able to be sent home in a single day after administration. Schizophrenics were able to be sent home after three days of treatment with the extract.
Then there were two shoes to the disaster. First Thorazine and another major antipsychotic drug were invented. Then the sanctified by Nobel prize Cyanocobalamin totally failed to replicate the results of the liver extract in many studies besides high MCV.
I know of several people hospitalized who were quite hallucinatory and whatever else is required for hospitalization who have had a family member feed them, MeCbl and AdoCbl who have had the hallucinations stop within 48 hours and released within a couple of more days..
I and many with B12 CNS deficiency symptoms have had multisensory hallucinations, potentially including every sense, that are basically noise in the circuit, like static or digital scramble on the TV. I could smell the clam flats in my basement changing suddenly to hot linen and other less pleasant things. My sense of taste was similarly afflicted as was my hearing. So if I were so inclined I could have made it into anything. I made it into meaningless noise that pointed to areas of damage of some sort. They all healed. I could once again taste strawberries, odors were normal, not changed and strengthened in weird ways and completely random at times. The visual and auditory hallucinations went away. Some changed in days, some specific things took months.
Also, during healing for me and others, which was running many symptoms in reverse, volatile emotional changes were common.
The thing is the deadlock quartet, as well as containing the real human active cobalamins, carnitine, and human active folate, l-methylfolate and it does appear to replicate the entire spectrum of effects of the concentrated liver extract. Good luck.
