Hmm.. this thread looks quiet... maybe I'm posting at the wrong place, but I had a question for Freddd: Does he recommend a pharmacy for the methyl B12 shots? and does he recommend a dosage per syringe?
Thanks,, this has been a fascinating read. I come from the lyme borrelious camp (many overlaps with ME/CFS imo...)
I just want to add to SaraM and anyone else relevant,
I tried out my glutathione and built up gradually as Freddd advised. I reached the point where it was making me feel very ill. It took two months to reach this point, building up the dose. This is exactly what Freddd predicted.
Either it does not agee with me at all or, as Fredd said, I am good with some, but the dose is critical. It definitely made me feel better for several weeks at the beginning.
For the time being I am holding off and I may resume at a later stage, but build the dose up very slowly. Fredd warned me about all this and I thought that two months was slow enough to tell how I was doing, but clearly it wasn't. Next time I will stay on a very low dose for longer and build up VERY slowly.
My recomendation to everyone is to follow Freddd's advice very carefully. this guy SERIOUSLY KNOWS WHAT HE IS TALKING ABOUT!!!
I hope Fred is around to comment.
My neuropathy is steadily getting worse in the past few months. I have lyme and co-infections (finally diagnosed in 2005 after no diagnosis for 9 years). I have been on intermittent antibiotics x 5 years.
The only thing different since the worsening neuropathy has been the addition of Jarrow methylcobalmin 5mg SL at bedtime and about 4mg 3x/week of SLC Univ Pharm meB12 sq injections. Also have added Metafolin 1-2 once/twice a day.
I take a bunch of other supps: MultiVit, B complex (both with meB12 and methylfolate); E, C, fish oil, zinc, Molyb, Vit K, magnes.
I have also added more calcium citrate and Vit K2 MK7 in the past two months as I have been diagnosed w/ osteoporosis.
Could the meB12 be methylating mercury?
thank you!
Dear Freddd,
I will keep my message short not to overload the current conversations. I don't suffer from many of symptoms you described but have had ME for 20yrs. Since you are knowledgeable about b12 and folates I'm wondering if you could give me some insight as to why my MCV is always in 95-97 range and my MMA is in the upper normal range. I don't have any reaction whatsoever with mB12 by Jarrow or hydroxy B12 injections, I've taken it in combo with different folates over the years. Currently I am taking Thorne #12 B-complex which contains the adenB12 + mB12 and 5 Methyl- tetrahydrofolate but will switch to the protocol you rec'd for better absorption.
My question(to save myself confusion, more expensive testing and shooting in the dark with supplements) is this, if I were to take your rec'd protocol and feel no obvious difference in my symptoms, would a lowered MCV result be a good indication that something is working?
I need to have some sort of indicator that I'm moving in the right direction because at this point the most debilitating part of my illness is stamina, PEM and the whole automonic dysfunction. More energy would certainly be a good sign but how long on these supplements that you rec'd do I continue to take them if nothing is changing.
Thanks!

Hi, Freddd.
I've been giving some more thought to the question of why glutathione supplementation was so disastrous for you, when ordinarily it is such an important and beneficial substance in the body, and in fact, as I think you know, the depletion of glutathione is what I have hypothesized as being the initial biochemical cause of the development of ME/CFS.
How about this:
It's known, and is in published research, that glutathione will react rapidly with other forms of B12 to form glutathionylcobalamin. This form has been detected as normally present inside cells, and this is part of the basis for thinking that glutathione acts as a protector of B12 at an intermediate stage of its metabolism inside the cells.
In your case, you are putting in the two coenzyme forms of B12 sublingually, and are apparently depending on them to diffuse into your cells, independently of the normal transcobalamin transport and importation processes.
What if glutathione reacts with these coenzyme forms before they enter the cells, and what if your cells are not able to convert glutathionylcobalamin back into the coenzyme forms? I think that would explain your observations, in the light of your report that you do have an inborn error of metabolism in the intracellular B12 processing enzymes. This may also be true of others whose cells are not able to make this conversion.
Best regards,
Rich
Hi Rich,
I do agree that the conversion of active b12s to glutathionylcobalamin is apparently occurring at a great rate and I certainly can convert it back to active at anything like the rate I need. I can't get enough b12 to my cells without diffusion.
For me mb12 made no difference in that but Metafolin did and glutathione demonstrated it's adverse effects by causing the increase in MCV by somehow decreasing the folate effectivness to which there are 3 clues; increased MCV, angular cheilitis and very much increased b12 visible in urine continuing every day until enough Metafolin is taken lowing it back immediately in the same way it did the first time I took it.
This is quoted from a couple of posts above. The question is why does it affect these folate specific items in me and those undergoing "glutathione detox reaction" which is moderately common. More and more people on this set of forums are posting their negative reactions to glutahione. In a more thorough piece I am preparing for you I am putting together I am including descriptions of "glutathione detox reaction" and comparing it directly to those symptoms and signs listed specifically for folate deficiency of which I have a number. This more complete list might very well point at what the biochemistry is for someone who knows and could see possible connections.
So why does Metafolin reduce urine output of b12 substantially? So why does glutathione increase excretion of b12 in the urine very substantially and maintains it? Why does glutathione cause angular cheilitis in a few days? Why does glutathione increase MCV and MCH and possibly other blood measures. Why does glutathione increase inflammation throughout the body. Why does glutathione increase asthma? Why does glutathione increase allergic responses and MCS. Why does Gltuathione increase the peeling and raggedness of skin around the nails and finger tips. I can duplicate all of these merely by not taking enough Metafolin each day. Though by merely not taking it the things don't start so hard or fast. I do get dietary folate and folic acid so it normally never gets as intensely bad as it got on glutathione and afterwards. Why does the "anti-folate" effect of glutathione start within 2 hours of first dose and last for at least 2 years afterwards for some people. The b12 deficiencies came on much slower.
Hi, Freddd.
Thank you for this very thought-provoking post!
Here's what I suggest might have gone on when you added the glutathione or glutathione precursors:
I suggest that the glutathione reacted with the methylB12 to produce glutathionylcobalamin. I suggest that your cells were not able to convert glutathionylcobalamin back to methylcobalamin because of a genetic mutation in the intracellular B12 processing enzymes, which you have reported having. This caused your cells to become deficient in methylcobalamin, which is a necessary cofactor for the enzyme methionine synthase, which links the methylation cycle with the folate cycle. This caused a partial block in both. In the folate metabolism, the result of this is a buildup of methylfolate, because it is not being utilized as a reactant in the methionine synthase reaction at a rate as high as normal. Because methylfolate does not have a glutamate tail, as other forms of folate in the cells do, it does not carry a negative charge, and thus is able to leak through the plasma membranes of the cells, into the blood plasma. The cells therefore become deficient in folates as well as methylcobalamin. This is called the "methyl trap" mechanism in folate research.
Since one of the roles of folate is to assist in the pathways for synthesizing purines and thymidine, and hence in the pathways for making new DNA and RNA, the deficit in intracellular folate in the cells in the bone marrow results in difficulty in making new red blood cells, which require DNA in the initial phase of their synthesis. The result is that fewer of them are made, so the available hemoglobin is put into fewer red cells, causing them to become larger than normal. This is the origin of the macrocytic anemia that is produced by either low folate, or low B12, which causes low folate by the methyl trap mechanism.
I suggest that when the cells have become low in folate as a result of the methyl trap mechanism (in the case we are discussing, this was initially brought on by methylcobalamin deficiency as a result of reaction of glutathione with methylcobalamin, and inability to retrieve the cobalamin from the glutathione binding) then if methylcobalamin is again added, the cells will not be able to utilize it properly, because methionine synthase will be partially blocked due to lack of enough methylfolate in the cells. The result is that the excess methylB12 will be excreted in the urine.
When methylfolate is then added in amounts large enough to restore the methionine synthase reaction, the cells will then be able to utilize methylcobalamin more efficiently again, so less of it will be excreted in the urine.
I don't think I can answer all the other good questions you posed, but I suspect that the above mechanism gives rise to the other symptoms you discussed as well. Some of them appear to involve the immune system. When folate goes low in the cells (which I suggest occurs as a result of the methyl trap mechanism in response to "trapping" of B12 by glutathione, in an irretrievable way in your case) this also particulrly affects the immune system and the gut, both of which depend on making new cells rapidly, and thus both of which need a generous supply of new DNA (This, by the way, is the reason why cancer chemotherapy agents that deplete folate particularly cause depletion of the red and white blood cells and unpleasant symptoms involving the gut). A partial block in the methylation cycle, which also results from this process, as discussed above, may also have effects on the immune system. It could be that glutathione actually becomes depleted in this process as well, even though adding it initially is what caused the problems in your case. Glutathione depletion definitely impacts the immune system, especially the cell-mediated immune response and controlling inflammation, which involves production of oxidizing species by the immune system.
The reason why glutathione becomes depleted is that a partial block in the methylation cycle appears to cause draining of sulfur-containing metabolites down the transsulfuration pathway, through sulfoxidation, and into excretion in the form of sulfate in the urine. This depletes the sulfur metabolism, and this in turn lowers glutathione. However, in your case, even though this occurs later in the process, a vicious circle mechanism has been set up, and the only way to break it is to add both methyfolate and methylcobalamin together, which you did, and it worked. This vicious circle mechanism, by the way, is the reason why the methylation treatments for ME/CFS all contain both B12 and folate together. Taking one of these two individually will not break the cycle. Both are needed. This is the real breakthrough that you discovered experimentally on your own, and that was also discovered in autism research by S. Jill James and coworkers, published in late 2004. The same is true in both ME/CFS and autism.
Anyway, I suggest that glutathione did not impact folate directly in your case, but rather indirectly, by lowering the availability of methylcobalamin, therefore shutting down methionine synthase, therefore provoking the methyl trap mechanism, which drained folate out of the cells, and thus resulted in symptoms of folate deficiency.
The remaining puzzle, to me, is why this process affects quite a few other people as well, according to what you have reported. Do they also have genetic mutations in their intracellular B12 processing enzymes? How common are these, actually? I don't know the answers to these questions.
Hope this helps.

Could the meB12 be methylating mercury?
thank you!
I just wanted to throw heavy metals into the mix. If you have hidden heavy metal toxicities, the Metafolin may be causing the problem...
I got a lot worse back in Oct-November after some of the methylation supplements were overprescribed by my doctor. I was prescribed 2 kinds of b12, and 3 different types of the active folates (from the simplified list).
The end result was severe anxiety, cramping, cold extremities, neuropathies, etc., all of which were a result of heavy metals (mainly mercury and arsenic) being dumped too quickly. I had to stop the methylation supps, and haven't restarted them yet, although I hope to soon...maybe in the next month. As both Freddd and Rich say, one needs these nutrients not only for detoxification, but for rebuilding the body.
So even though I had almost the worst possible reaction to the simplified protocol, I'm grateful for it in a weird way -- it proved once and for all that I have carried a serious burden of stored heavy metals, and need to slowly chelate them out. I've restarted the Cutler protocol to do this as safely as possible.
By the way, Cutler says that methylb12 does not methylate mercury. I don't have the exact quote here, but he said something like if it did, we wouldn't have problems that some of us do. The mercury in fish is in the methylated form, that's why they can handle it with no problem. Again, not an exact quote, but something along those lines.
Best regards,
Dan

Hi, Dan.
Here's a repost from another thread that addresses methylB12 and mercury.
Rich
My concern about methylB12 is related only to its possible potential for methylating inorganic mercury that may be in the body, primarily from exposure to mercury vapor, as is released continuously from amalgam fillings in the teeth. Methyl mercury is readily able to cross the blood-brain barrier and enter the brain, where it apparently then reacts with enzymes containing selenium (and to a lesser extent, sulfur) and acts as a neurotoxin, with a residence time in the brain measured in years.
I do not have proof that this will actually occur in humans with the inventories of inorganic mercury that are actually present and the dosages of methyl B12 that are used in treating ME/CFS.
My concern comes from the fact that there are published papers indicating that methyl B12 is able to react and donate a methyl group to inorganic mercury, and in fact, it is one of the only substances in biological systems that is able to do this. The reason is that inorganic mercury exists as a doubly positive mercuric ion (Hg++). In order for a substance to donate a methyl group to it, the substance must be negatively charged. methyl B12 forms a carbanion, which is able to do this.
It is known that the way methylmercury enters fish is that bacteria in aquatic environments use methyl B12 and other similar substances to methylate mercury, and then are eaten and travel up the food chain to the larger fish. Apparently the bacteria methylate the mercury as a means of exporting it to their outer surfaces and so protecting themselves from its toxicity. It can have some toxic effects on fish (see first abstract below) and when people eat fish containing methylmercury, it can be toxic to them, especially if their bodies are low in selenium (see second abstract below). Methylmercury dumped as waste into the ocean in a fishing area was responsible for the Minimata disease disaster in Japan in the late 1950s, and methylmercury used to treat grain seed that was unfortunately later eaten by people caused a disaster in Iraq as well.
There have been experiments in guinea pigs in which it was found that methylation of mercury occurred in their bodies. It is not clear whether this methylation occurred within their own metabolism, or whether it was carried out by bacteria in their gut.
As far as I'm concerned, this is an issue that has not yet been resolved. I'm aware that people with certain polymorphisms will benefit more in terms of helping their methylation cycle by taking methyl B12 rather than hydroxo B12. I know that there are people who are taking dosages of methyl B12 of several milligrams per day, sublingually, and some are reporting benefits. I don't know what their body burdens of inorganic mercury might be. Unfortunately, there is no good way of evaluating it, short of doing autopsies, which isn't very helpful for people who want to keep living for a while!
It may be that supplementing with selenium will give sufficient protection from methylmercury toxicity. This approach is actually used by marine animals and birds, who eat seaweed, containing selenium, together with fish containing methylmercury. Some whales have been found to have large deposits of selenium-mercury compound in their livers. This is very chemically stable, and makes them both non-bioavailable. It should be noted, however, that selenium is toxic in large amounts as well, and the Institute of Medicine has placed a recommended upper limit on selenium supplementation of 400 micrograms per day. Some have argued that this limit is too conservative. The safe upper limit for an individual probably depends on a number of factors, the body burden of mercury being one of them, but it is difficult to determine what it should be on an individual basis. The Institute of Medicine attempts to set a limit with a safety factor that will apply to the general population.
I wish I could give you a more definitive answer to your question, but that's as much as I know. It's possible that I am being overly cautious in raising this issue, but I really do not want people to be harmed.
Best regards,
Rich

Reproductive, developmental, and neurobehavioral effects of methylmercury in fishes.

Abstract
In the decades since the Minamata tragedy in Japan, there has been a considerable body of research performed on effects of methylmercury in fishes. The studies have revealed that some of the most sensitive responses seen in fishes are reminiscent of the symptoms experienced by the Minamata victims. This article reviews the literature, with a focus on mercury's effects on fish reproduction (hormone levels, gametogenesis, fertilization success), embryonic development (morphological abnormalities, rate), the development of behavior, and neurobehavioral effects in adults. Both experimental exposures and epidemiological approaches are included. There have been many studies demonstrating delayed effects of mercury exposure in that exposures during one life history stage can produce effects much later during different life history stages. For example, exposure of maturing gametes can result in abnormal embryos, even though the embryos were not themselves exposed to the toxicant. Exposures during sensitive embryonic periods can produce long-lasting effects that can be seen in adult stages. The existence of these manifold delayed effects renders the practice of short-term toxicity testing particularly unhelpful for understanding the effects of this (and other) toxicants.

Dietary selenium's protective effects against methylmercury toxicity.

Abstract
Dietary selenium (Se) status is inversely related to vulnerability to methylmercury (MeHg) toxicity. Mercury exposures that are uniformly neurotoxic and lethal among animals fed low dietary Se are far less serious among those with normal Se intakes and are without observable consequences in those fed Se-enriched diets. Although these effects have been known since 1967, they have only lately become well understood. Recent studies have shown that Se-enriched diets not only prevent MeHg toxicity, but can also rapidly reverse some of its most severe symptoms. It is now understood that MeHg is a highly specific, irreversible inhibitor of Se-dependent enzymes (selenoenzymes). Selenoenzymes are required to prevent and reverse oxidative damage throughout the body, particularly in the brain and neuroendocrine tissues. Inhibition of selenoenzyme activities in these vulnerable tissues appears to be the proximal cause of the pathological effects known to accompany MeHg toxicity. Because Hg's binding affinities for Se are up to a million times higher than for sulfur, its second-best binding partner, MeHg inexorably sequesters Se, directly impairing selenoenzyme activities and their synthesis. This may explain why studies of maternal populations exposed to foods that contain Hg in molar excess of Se, such as shark or pilot whale meats, have found adverse child outcomes, but studies of populations exposed to MeHg by eating Se-rich ocean fish observe improved child IQs instead of harm. However, since the Se contents of freshwater fish are dependent on local soil Se status, fish with high MeHg from regions with poor Se availability may be cause for concern. Further studies of these relationships are needed to assist regulatory agencies in protecting and improving child health.
