These are based on thousands of injections, sublingual and large oral doses and the visible variations in coloration dependent upon folate effectiveness. ARBITRARY SCALE – excretion of cobalamins influenced by folate effectiveness state based on observed cobalamin excretion in urine at 30mg/day injected in 3 doses. 128 - Methyltrap, Glutathione – extreme levels of cobalamin seen in urine, up to maximum excretion rate if sufficient cobalamin available 64 - Partial methylation block, Folinic acid – noticeably increased levels of cobalamin in urine 32 - Partial methylation block, Folic acid – noticeably increased levels of cobalamin in urine 16 – Partial methylation block, Folic acid with 400mcg of l-methylfolate, noticeable levels of cobalamin in urine 8 - Partial methylation block, Folic acid with 16 mg of l-methylfolate, noticeable levels of cobalamin in urine 4 - Partial methylation block, L-methylfolate, some donut hole deficiency, minor visible amounts of cobalamin 1 - Adequate l-methylfolate, basically no visible cobalamin with dose sizes that usually produce visible cobalamin under all other circumstances. In addition, there is a maximum amount of cobalamin that can be excreted. Based on ultra high dose such as the 5 grams or more as is used for cyanide poisoning as well as 500mg + infusions in private trials and some other high dose (180mg injections) trials with puzzling results.. The maximum execrable cobalamin by kidney appears to be in the range of 5 to 20mg per hour and the results are no longer puzzling. So now I know why Country Life Dibencozide caused so much more visible cobalamin than does Anabol Natural; folic acid.
