I have had B12 checked, it was very high because I was atcually supplementing it at the time! So we cannot know how its my real status.
I was defficient in almost every other vitamin though, from B6 to A. I know I have intestinal inflammation, candida and malabsorption. The worst its that these late years I cannot even sleep, this is slow death wtf!
How its that cleanse? I have done from daily coffee enemas to water fasting. ALthough both are helpful and interesting, given time the two caused my intestines to flare up, Water Fasting the worst. I still do coffee enemas from time to time, they are valuable at detox.
