While healthy people need just a tiny trace of Methylcobalamin to avoid a frank deficiency, a massive body of evidence powerfully supports the conclusion that supplementing with megadose levels of Methylcobalamin - and not regular B12 - can protect brain and nerve cells against toxins, help the healing of damaged neurons, and even provide powerful nutritional support in neurodegenerative diseases.
Paralyzing Viruses
Several groups of scientists have investigated the use of Methylcobalamin in Bell's palsy, and they have uniformly found that Methylcobalamin speeds the recovery of normal nerve function. In two separate human trials, patients were given either prednisone alone (a steroid anti-inflammatory drug commonly used to treat Bell's palsy), Methylcobalamin alone, or the drug and the coenzyme together. Both trials found that the time required for complete recovery was significantly shorter for people who took Methylcobalamin (whether in combination with prednisone, or even by itself) than for those who took the steroid drug alone.
Multiple Sclerosis (MS)
In a pilot trial, six people with degenerating MS received 60 milligrams of Methylcobalamin a day. The scientists compared the changes which took place in the patients' nerve function over the course of up to two years before the trial began, to the changes which happened during the six months in which the patients took Methylcobalamin. They found that there was a significant improvement in nerve function while patients took Methylcobalamin. Before Methylcobalamin, about one fifth of all measurements of nerve function suggested that the nerves were degenerating. While the patients were supplementing with Methylcobalamin, however, only half as many nerve measurements showed signs of degeneration. And while, in the time before the trial began, just 4% of the nerve measurements suggested that the nerve in question had improved, it was found that 18%, or four-and-a-half times as many nerve readings, showed signs of improvement while patients were taking Methylcobalamin.
Lou Gehrig's Disease
In a randomized, double-blind, controlled trial, 24 patients with Amyotrophic Lateral Sclerosis (ALS), better known as Lou Gehrig's disease, took megadoses of Methylcobalamin through intramuscular injection for just under a month at one of two doses (25 milligrams or 500 micrograms a day). While no results were seen in the lower dose, patients who took the higher dose of Methylcobalamin experienced increases in measurements of their nerves' ability to trigger responses in the muscles. Two patients' gaits were also noted to improve in the higher-dose group.
Alzheimer's Disease
Two trials have between them found that giving Methylcobalamin to people with Alzheimer's disease or related dementias (like Pick's disease) leads patients to have better interaction with other people and with the world around them, while improving mood and relieving neurological symptoms. The evaluation by the patients' familes and physicians was also improved. The findings in these trials on intellectual functioning were inconsistent: some scales showed improvements, but others did not. Both of these trials, however, used relatively low doses of Methylcobalamin.
A Good Guess: Parkinson's Disease
There's good reason to believe that Parkinson's disease is caused and/or accelerated by "excitotoxicity" resulting from overstimulation by the neurotransmitter glutamate. Drugs which lower glutamate levels, or which "tune down" its receptor, improve many of the symptoms of the disease, while drugs which stimulate the receptor make them worse.
So if Methylcobalamin protects neurons from the toxicity of glutamate, might it provide support for people with Parkinson's disease? Unfortunately, no clinical trials have yet been run to test this idea. But granted how safe Methylcobalamin supplements have proven to be, and its clear benefits in other neurodegenerative diseases, this essential coenzyme holds out hope as a potential way to prevent, and perhaps even to treat, this debilitating disease.
Caramelized Nerves
A string of clinical trials have reported that Methylcobalamin improves nerve function in people with diabetic neuropathy as demonstrated by things like improvements in the ability to detect gentle vibration, reduced tingling, numbness, and pain in the extremities, less feelings of "heaviness" in the legs, and the restoration of neurons' ability to efficiently transmit a signal and to properly regulate the heartbeat. Trials which have looked at the overall improvement of patients' neuropathic symptoms and signs have also reported remarkably positive results.
Eyes Under Pressure
In a controlled study, 14 patients with normal-tension glaucoma were treated with Methylcobalamin, and their progress was compared with that of 22 other normal-tension glaucoma patients who did not take Methylcobalamin supplements. While 59% of the people not taking Methylcobalamin experienced worsening sight, 86% of patients taking Methylcobalamin experienced no loss of function.
The Squeezing Spine
Lumbar spinal stenosis is the compression of the nerves in the lower spine caused by arthritis, spinal degeneration, injury, or sometimes unfortunate genes. The squeezing of the nerves leads to pain on exertion in the lower back or buttocks, which is relieved by shifting position. In a single-blind, randomized controlled trial, 152 people with lumbar spinal stenosis were given the current standard care (physiotherapy, standard drugs, and education on managing their disease), and additionally either did or did not take Methylcobalamin. For whatever reason, the dose chosen for the trial was very low (half a milligram) compared to what has been used successfully in most trials pitting Methylcobalamin against nerve disease. At this low dose, there was no improvement in pain or in the doctors' evaluations of the appearance, sensation, or function of their nerves; however, despite the clearly inadequate dose, those people who took Methylcobalamin found themselves able to walk further distances without experiencing pains than people who were not taking it.
The Question of Dose
In general, most trials in which Methylcobalamin has been used to help people with various forms of diabetic neuropathy, non-diabetic neuropathy associated with uremia, peripheral facial paralysis (including Bell's palsy and Ramsay Hunt Syndrome), normal tension glaucoma and dementia (including Pick's disease and Alzheimer's disease) have used doses ranging from1.5 to 5 milligrams. On the other hand, trials involving victims of ALS (Lou Gehrig's disease) and multiple sclerosis (MS) have used much higher doses, such as 25 milligrams per day for ALS and 60 milligrams daily for MS.
Note that in some cases only one trial has ever been performed, with only a single dose used, and the results are often preliminary; it's therefore possible that higher (or lower) doses might be more effective. Because of the well-established safety of Methylcobalamin, many nutritionally-oriented physicians are working with their patients using doses considerably higher than those used in the relevant trial. There are some cases where this has seemed especially prudent to some physicians.
For instance, the evidence suggests that Methylcobalamin is much more effective against Bell's Palsy when taken within days of the initial attack; at later times, a higher dose might be more appropriate. Likewise, the only trial of Methylcobalamin in patients with lumbar spinal stenosis used only 0.5 milligrams per day - and achieved only very minor results. It seems reasonable to speculate that a higher dose might have been more effective, granted the fact that nearly all successful trials in other neurological disorders have used minimum doses of 1.5 milligrams, and many have been higher. Discuss these issues with your doctor.
There are also several neurological disorders in which there is reason to believe that Methylcobalaminmight make a good supplement choice if your physician approves, but in which no clinical trial has been performed. These would include Parkinson's disease, tinnitus, Spinal Muscular Atrophy (SMA), and people suffering with environmental illnesses who suffer with neurological signs and symptoms. In such cases, because we don't have formal human trials to use as a guideline, your physician will have to rely all the more strongly on his or her judgement.
A range of Methylcobalamin sublingual supplements are now available, making customizing your dose more convenient and affordable than at any time in the past.
