It can take years of cell making to grow enough TCR-Li as far as I experienced and have observed in others . B12 was identified in 1948 and the 1950's studies had no idea about the lithium TCR-Li as to how fluoride can disable B12. They started researching with no understanding of fluoride disabling the TCR-Li. we were disabling the B12 and didn't have any idea. Many still believe that it can't be absorbed in the mouth. I used CyanoCbl and folic acid and kept reading until I found why that may not be usable for some people. After decades of taking CyanoCb;l and folic acid and I had 200+ symptoms of B12-folate deficiency symptoms.
Five minutes after putting the first MeCbl tablet sublingually. I knew my life was changed. Instead of having lots of streps and pneumonias all my life to that point, I haven't had any of that after taking MeCbl sublingually in 2003. With methylfolate essentially everything started healing and I needed very quickly that I also needed 4000-5000 mg of potassium daily. At my internist's, each 3 weeks, as I was dying from congestive heart failure 12-13 years after first diagnosed, and everybody in the office could SEE the differences. The visible changes lasted for about a year. Healing all 200+ symptoms took 17 years.
In that period, I have had a single cold just a couple of weeks ago. The previous last illness was a pneumonia in March of 2003. And obviously I didn't die of congestive heart failure in 2003 or 2004. I lost 45 pounds of water in a month, twice. First with starting methylfolate and had another loss of another 45 pounds of water in a month. with starting L-carnitine fumarate.
I do not believe that that there is any need to get rid of your fillings. When I went deficient of Boron, I had as the dentist called it "Wild fire" decay. and all my uppers were removed. I had started boron that week. When I went back 2 weeks later for the lowers and the "wildfire" decay stopped with the 3 weeks of boron supplement with MeCbl, and methylfolate and a B-complex without CyanoCbl and/or folic acid.
In the course of things they were replaced as the teeth eroded or removed for cause of more decay and the "wildfire" decay stopped cold with a Boron supplement with the MeCbl, AdoCbl and methylfolate. I have had 2 lowers removed 20 years after starting the Boron.
