Dreambirdie, good luck. I'll be looking for you on the methylation train.
Cloud, it's possible that your lack of response to methylcobalamin has to do with the brands you chose to try. Freddd has done some surveys on brands and there are only a couple that seem to work for most people. This isn't necessarily a reflection on the brand; there's at least one company whose quality is really good, but their SLmb12 doesn't seem to work well for most of us.
You are probably responding more to the hydroxycobalamin because cyanocobalamin is pretty close to totally inactive until our bodies convert it - if they are able to. Some of us could never make the conversion; others (like myself) no longer can. You might want to read the first 3 pages of this thread, where Freddd lays out his understanding of the different types of vitamin b12 and the dosages your body actually receives, as opposed to the dosage on the syringe or bottle. He believes the sublinguals he recommends are actually more effective than hydroxycobalamin injections. Rich thinks differently, or at least that's how I read it. I think we're actually lucky to be a part of Freddd and Rich's debates and the experiments around them; different perspectives allow us to see further, and with more depth.
Hi Cloud, dreambirdie et al,
I think it's a good time to go over a few basics of what I did, and did not do, and what is conjecture versus results just to clarify things. I admit that sometimes I get frustrated that I have trouble communicating what I see so clearly see, but that is a probelm I have had for a long time. I sometimes take logical shortcuts that others don't follow.
I and 4 other hypersensitives to active b12s did comparative testing of 10 brands of sublingual methylb12.
Jarrow 5mg and 1mg and Enzynamatic Therapy 1mg came out as 5 stars, superior and able to make a difference over all other brands and no other brands were able to have a differential effect over them. Reporting only the unanamous results, those two were equal. In my experience, unduplicated by the other 4 , the Enzymatic Therapy was very slightly better. During the first year of most rapid healing I took both brands daily just to be sure. Country Life Dibencozide, the only sublingual adenosylb12 tested was fully equal to the 5 star brands of mb12 judging purely on it's dramatic effectiveness by all 5 testers. No other brands of methylb12 exceeded 1.5 stars when considering the size of the performance differences. One brand was ZERO stars, totally indetectable by all 5 testers allowing full and rapid return of all symptoms.
As I inject methylb12, with my doctor's cooperation I did a series of injections titrating for effect. I found that 1-6mg per subcutaneous injection were all about the same except for urine coloration. At 7.5mg something different happened and there was a dramatic central nervous system effect. From 7.5mg to 25mg SC in a single injection there was no additional difference except for urine color. Others have duplicated this.
Furthermore adenosylb12 and methylb12 each had their own specific effectiveness at the 7.5mg dosage. Others have duplicated this.
In adjusting frequency I found that 4x7.5mg sc daily or 3x10mg sc daily maintained maximum CNS effectiveness in causing healing of CNS damage. Others have duplicate this and some have found that 2x15mg works as well for them.
In another series of tests in calibrating subligual absorbtion under lip and/or tongue, 45-120 minutes of tissue contact of 50/51mg of sublingual tablets as a single dose produced the same CNS effectiveness and urine coloration as 7.5mg - 12.5mg injection. This corresponded with 15-25% absorbtion of the sublingual in 45-120 minutes.
For ME. due to the hypothecized rare genetic condition, I find cycbl and hycbl virtually totally ineffective. It only takes a few minutes of light exposure of injectable methylb12 to change enough of it to hycbl that it gives me acne type lesions and allows neurological deterioration to resume reversing previously made gains. Other people have duplicated this. This happens in way too many people to account for it via some hypothetical rare genetic cause
In another situation I recruited persons who were sensitive to b12 but not hypersensitives. They were never tested on any but 5 star methylb12 and adenosylb12 or both. They did no comparitive testing of brands. I gave them free bottles of b12, when needed, which they took for a month and then we tried challange doses of the other variety. There was no control over whether they took cofactors or anything else of the sort. It was done very early in learning about these things and needs to be redone properly.
In dozens of people tested, those having separate responses to methylb12 and to adenosylb12 after equilibrium is reached on the other methylb12 or adenosylb12, in almost 100%. This happens in way too many people, almost everybody, to account for it via some hypothetical rare genetic cause.

Obviously there is one set not yet tested, looking for differential effectiveness of hycbl over equilibrium mb12 and adb12.
My testers were pretty sick of me and all the setbacks they kept having after trying these other things. They went on strike. I was sick of the setbacks too and out of money. At this point we just set out to elliminate setbacks and keep healing continuous which has not been nearly as easy as it might seem.
I am making the best progress I have ever made on reversing the numbness in my feet the past few months and have had no setbacks in that time for the first time ever. I am controling light exposure all along the course of the mb12 including the draw into the syringes and I am taking oral Metafolin with each injection. Each little increment of improve,ment has made a difference.
Of those who have tried suprathreshold doses of 7.5mg-15mg (50/51mg sublingual), not everybody finds a difference.
Those that do find that it makes a difference in things, find that is is generally in damage that they have generally been told to expect to be "permanent".
In ALL of these various things with all forms of b12, cofactors such as Metafolin can make a huge difference in overall perfomance.
