I did a trial of 1.5 mg methylcobalamin 4 times a day and that was positive. I then increased physical activity and had 3 days of a downturn and recovered. I then reduced to .75 mg with no decline. I increased physical activity for three days and had a downturn. I then added .06 mg of methylcobalamin and recovered in one day.
This is consistent with my understanding gained from the many trials that I have done over the last 3 years.
I also take adenosylcobalamin orally 6 mg orally with each injection. This is consistent with my understanding of sublingual administration of all forms of Cobalamin.
Hydroxocobalamin for me is effective, Methylcobalamin with Adenosylcobalamin is more effective than Methylcobalamin alone and more effective than Hydroxocobalamin. The three together are the most effective. Specifically for mucusy, lack of appetite, anxiety, brain fog, and energy levels, effectiveness of sleep, and tooth pain. I like being me more.
I only have a vestige of peripheral neuropathy which was debilitating before I administered Pyridoxal 5 Phosphate. B6 deficiency is rarely diagnosed and usually in conjunction with other deficiencies and treatment is for life. Reasonable to assume that my peripheral neuropathy would have been permanent had I not self-diagnosed and self treated my B6 deficiency. My damage is not permanent although it was declared to be. Diagnosis is typically made clinically by the administration of B6.
I have come across in my reading "Some people who experience transcobalamin issues seem to benefit from megadoses of B12." The only study I have come across was from China and people were prescribed 5 mg of hydoxocablim. I wonder if some clinicians are referring to people like me to try larger doses.
I am not prone to regret. I do lament the 2.5 years I tried to conform to the current understanding of B12 deficiency. I did improve but slowly and experienced the roller coaster of using up my B12. The B6 was easy as I needed to be in less pain and was successful.
It is emotionally difficult for me to self-treat the way I do. Getting easier as it is easier to be me.
