Hello I am on this forum for a couple of months because of a b12 deficiency. When I started the protocol I had startup effects but they went away after 2-3 days. Then I felt wonderful , my b12 symptoms improved, my hair and nails got very shiny,.. Then I got a potassium deficiency and stopped because I didn't know what it was. 2-3 months after that I started the protocol again. The problem is that it suddenly stopped working. My symptoms didn't improve, my hair didn't get shiny again, I didn't got the low potassium. I take 2,5 mg b12 a day with 1mg folate. I also take zinc, magnesium and fish oil. I'm trying 2 months now and still nothing happens. I started a b-complex again because I thought maybe that was the cause. (I tried taking a b-complex before but it made me feel jittery and depressed) But still nothing changes and the b-complex makes me very depressed. I also have high potassium now for more than a month because I was potassium loading without having low potassium. I don't know what is going on and why the b12 doesn't work anymore. I tried increasing folate but it doesn't change anything. Or maybe the high potassium stops the b12 from working? I am so hopeless and depressed. Does anyone have any idea?
