1 ) So you are saying I should take Metafolin + Jarrow Methylb12 5mg + Enzyamtic Therapy 1mg B12 infusion + Source Naturals Dibencozide daily ?? Should I take the dose mentioned on the bottles ? Metafolin daily, Jarrow mb12 5mg daily, the ET 1mg can wait until you see if you need a little more help, Source Naturals Dibencozide, half a tablet twice a week is probably fine. Things may need adjustment later after everything is running smoothly. 2) You mention that one should also take potassium. We do not get plain potassium supplements here so could you tell me which one I can order from iherb? Really? What about Salt Substitute (LoSalt) at the supermarket? That would do fine. I take the NOW Potassium Gluconate. As each tablet is only 99mg and I take 12-18 tablets a day (you may not need anywhere near that) I go through a lot. That makes it heavy and bulky for actually very little. The powders below would be a MUCH less expensive and much lighter for shipping. The potassium chloride powder is 730mg per 1/4 teaspoon. You would have to mix it in a large glass or water or whatever the instructions are. http://www.iherb.com/Now-Foods-Potassium-Gluconate-100-Pure-Powder-1-lb-454-g/13939?at=0 http://www.iherb.com/Now-Foods-Potassium-Chloride-Powder-8-oz-227-g/777?at=0 3 ) What about the other co-factors you mention - should I do that later - for eg Sam-e , L-carnitine fumarate ?? Those are for later unless you are a vegetarian, then the l-carnitine fumarate is needed now. http://www.iherb.com/Doctor-s-Best-Best-L-Carnitine-Fumarate-855-mg-180-Veggie-Caps/4939?at=0 is the best buy right now. 4) Is this protocol ok to do even though one has regular b12 blood levels ? Is there a danger of too much ?? Regular blood levels can leave a person with hundreds of deficiency symptoms. 5) Is it ok to take LDN while on your protocol ? I don't know but I don't see why not. 6) Could tender or poky feelings in the scalp be related to b12 ? ( I did read the list of symptoms you listed and it seems this could be one ) I'm not sure what you mean, but could be.
