I was on it for a while. Found it to work best for me; tried cyano-B12 and hydroxo-B12 and neither worked ok for me. I think one reason the methyl-B12 works so well is that the methylation cycle in many with Lyme is suppressed or low. This means that they need to intake more methyl- than a "normal/healthy" person to meet their metabolic needs. There is a methyl version of Folic Acid that can be very helpful also.
