A quick question:

"Though there are many forms of active folic acid, there is only 1 specific form of conjugated and reduced folic acid that the body can attach B 12 to."

And that form is...?

Thanks in advance!

Hi, Dan.

I'm guessing that they are referring to 5L-methyltetrahydrofolate. B12 is used as a coenzyme by methionine synthase to transfer a methyl group from 5L-methyltetrahydrofolate to homocysteine.

Best regards,

Rich

Thanks Rich -- as always. Really appreciate your help. :)

(I'm assuming that's the same as metafolin...)
