Why is vitamin B-12 as a supplement or additive dangerous?
Many Universities have published articles on the ability of Vitamin B-12 to convert mercury vapor into the much more deadly “Methyl mercury”. Methyl mercury knows no barriers, and creates far more havoc than other mercury chemicals, because of its ability to travel anywhere in the body without inhibitions. Sometimes the effects of high doses of Vitamin B-12 (over 50 micrograms) take months to correct.
Glutathione is not usually well absorbed from the G.I. tract, but it binds mercury, so taking a dose immediately before the dental procedure and another dose immediately afterward can bind mercury that may get swallowed.
