Hi there, I have attempted methylation protocol once with disastrous results. At first we thought it was potassium deficiency, but now that I'm looking at the ingredients on all the suggested supplements they all have fructose or sweetener of some sort (xylitol, sorbitol, etc etc) or something else I can't have (rice flour, soy, gluten, etc). I have severe fructose malabsorption and can't tolerate any amount of that stuff. Is my only option injections or does anyone know of B12 supplements that are free of all typical allergens/sugars? I have SEVERE leaky gut and react to gluten, soy, corn, rice, sugar, fructose, eggs, dairy. It seems impossible to find a supplement that is free of ALL these things. I found a spray ( http://n4hresearch.com/nutritional_supplements/B-12-MC-Spray.html ) but you can't divide the dose as easily, and I am so sensitive to everything that I have to start at super low doses of everything. Any thoughts would be appreciated.
