Vitamin C: metals are usually locked into the brain cells, after they have been oxidized (= loose their electron(s) of the outer orbits) by the intracellular enzyme catalase. In this form they are firmly bound to proteins or peptides. Vitamin C delivers free electrons to the intracellular environment. Metal ions become reduced and return to their metallic form. For example mercury returns from it's Hg + or Hg ++ back to Hg0. In this form mercury becomes a gas at body temperature and crosses cell membranes and tissues with no problem. It can therefore leave the cell and get in contact with extracellular proteins, where it loses its electrons again. From here it is easier for the body to eliminate Hg by using the sulphhydryl-group containing aminoacids, peptides or proteins (such as glutathion or cysteine) or by using porphyrin-compounds. Hg can be exchanged in the mucous membrane of the gut into vegetable fiber residues inside the fecal matter etc. Intravenous Vit C is far superior to oral Vit.C in accomplishing this task.
