Regarding the different forms of Vitamin b-12, there is this from Wikipedia:
http://en.wikipedia.org/wiki/Vitamin_B12
The part about producing cyanide is interesting. I'm not sure if it's relevant or not, but have never seen that before.
So in most cheap supplements you tend to see cyanocobalamin. The more expensive and "active" version, methylobalamin is typically found in more expensive supplements. I believe it is this process of converting Cyanocobalamin to the active methyl form that some people have a problem with. Without B12, you have bad Methylation, which can lead to all sorts of health problems.
The same is true with vitamin B6 and folic acid. Those are both needed for proper methylation along with various other processes in the body.
The active form of B6 is pyridoxal 5'-phosphate, but in cheap supplements it is usually in the form of pyridoxine. Again, like with b12, some people have a problem making this conversion.
Folic acid, same thing. Methyl tetrahydrofolate is the active form (and more expensive), while folate is the form typically found in supplements.
These "active" b-vitamins are not "natural" from my understanding. They are just forms that bypass a process that is often broken in the body, thereby delivering these vitamins in a more efficient manner.
Some people do just fine with the cheap forms of these vitamins, but others can't seem to utilize them. I noticed a big difference when I switched to using the active form of b-vitamins, these were recommended using the UltraMind Solution quizzes. So here we have an example where the "naturally occurring" form of a vitamin isn't always the best one to take.
Keep in mind, Dr. Mercola runs a very large internet business and he does have to market what he sells. I have and still buy some of his products from time to time, but it pays to understand what you're buying, OSIT.

A common synthetic form of the vitamin, cyanocobalamin, does not occur in nature, but is used in many pharmaceuticals and supplements, and as a food additive, due to its stability and lower cost. In the body it is converted to the physiological forms, methylcobalamin and adenosylcobalamin, leaving behind the cyanide, albeit in minimal concentration. More recently, hydroxocobalamin (a form produced by bacteria), methylcobalamin, and adenosylcobalamin can also be found in more expensive pharmacological products and food supplements. The utility of these is presently debated.
