The Right Kind of Vitamin B12 is Methylcobalamn — Kerri Knox


Once someone has overcome all of the hurdles to get appropriate testing and is told that they have vitamin B12 deficiency, there is still a problem to overcome- getting the right KIND of vitamin B12.

There are several kinds of vitamin B12 that are all CALLED vitamin B12, but only ONE, methylcobalamin, is the form that should be used in the vast majority of cases. Yet few doctors use methylcobalamin, favoring using their prescription pads and tradition over good science in their decision to supplement this vital vitamin.

When talking about vitamin B12, this is actually a generic term for a class of compounds called the Cobalamins, and indeed when one has vitamin B12 deficiency, it is more scientifically called Cobalamin Deficiency. This makes perfect sense when you understand that the various formulations of Vitamin B12 all end with the suffix Cobalamin.

While there are MANY `Cobalamins`, only three are generally used as dietary supplements, namely:


All three types are considered `Vitamin B12`, they are NOT all the same and using the right one can be a critical decision.

Cyanocobalamin is probably the most commonly used in the medical world and is often given as `B12 Shots` in a doctor’s office for those with certain medical conditions. But cyanocobalamin is actually the WORST choice, despite the fact that doctors in the U.S. are more likely to prescribe it over any other form.

Not only does cyanocobalamin require a higher dosage for the same effectiveness of hydroxycobalamin, but it is Entirely Ineffective for several different conditions related to vitamin B12 deficiency.

As such, it has been suggested repeatedly by several researchers, starting with Dr. AG Freeman in 1970, that cyanocobalamin should be removed from the market. While Great Britain followed through with researcher recommendations and removed the inferior product, doctors in the the U.S. have no such restrictions and still use cyanocobalamin routinely.

While Japan uses methylcobalamin nearly exclusively and it is the form present in prescription vitamin B12 there, the U.S. has virtually ignored the hundreds of studies that show the benefits this simple vitamin can bring.
