Here is interesting information about the vitamin B12. This vitamin is thought to help EHS sufferers .

THE BLOOD BRAIN BARRIER (BBB)
Because the BBB is compromised with EHS, Methylcobalamin B12 injection protocol is essential for patients with environmental sensitivities. (This is different to Cyanocobalamin B12 that is commonly available) For those who cannot stomach injections, a sublingual form is available at health food stores but will not be as effective.
The blood-brain barrier is created by the cells which line the small blood vessels (capillaries) of the brain, called endothelial cells. These cells form tight junctions between each other, which are not generally present in most organs, and stop a free exchange of substances occurring between the blood and the brain. This barrier protects the brain and creates its unique environment. (Begley, 2005) (6)
Methylcobalamin is the active form of vitamin B12 and triggers regeneration of the nerves without adverse side effects. It facilitates methylation, the process that creates and maintains nerves and brain chemicals.
“…… Ultra-high doses of methylcobalamin even promote nerve regeneration in experiments.” (The Journal of Neurological Science, April 1994)
(Recommended by the doctors at the Environmental Health Clinic at The New Women’s College Hospital)
The Methylcobalamin Protocol for patients with environmental illness is:
Methylcobalamin injection 25,000 IU/cc (preservative free)
5cc vial X6R
0.1cc subcutaneously daily or 2-3x per week or as directed.
It is best to use an Insulin syringe 3/10cc (painless)(#30)
Keep refrigerated and discard after expiry date
(Kathleen Kerr MD, 2005)
You must purchase Methylcobalamin at a Compounding Pharmacy. Your regular pharmacist can help you find one near you. Although this is most likely not covered by your insurance company, (it is not very expensive)
