... To my understanding:
There are three forms of B-12 available.
- Cyanocobalamin
- Hydroxycobalamin
- Methylcobalamin
The prefixes cyno, hydro, and methyl refer to the delivery method the cobalt (B12) is attached, allowing the element to pass through and allow methylation in the liver, converting the element cobalt into its vitamin form. Of these three forms, cyanocobalamin is considered the lowest grade. It is possible that, as the liver breaks down the cobalt and separates it from the cyano agent, the liver "may" convert the agent into a form of cyanide and possibly causing the liver to stop and control the toxicity first, disregarding the cobalt and it's methylation into B-12, or at least a loss of efficiency in its translation to B-12.
If true, this leaves methyl and hydroxy forms. The most "natural" would be Methylcobalamin, as this is closest to the liver's methylation process. However, I've read one doctor favored Hydroxycobalamin to allow the liver to methylate in a way most natural to that individual.
My explanation is rudimentary. If someone knows more on methylation in the liver and cobalt forms, please offer more insight. Would like to know more myself on this.
Perhaps Stewie...
