What is B12 (Cobalamin)?

B12 is such an important vitamin that is critical to the energy production and metabolism of every cell in your body.  B12 is important for DNA synthesis and expression, healthy red blood cell production, white blood cell production, and the proper function of your nervous system.  B12 is plentiful in animal products, such as meat, poultry, fish, eggs, and dairy; although some non-animal products come B12 fortified.  B12 is absorbed in the intestines by “intrinsic factor,” a glycoprotein produced in the stomach, and our ability to absorb B12 is significantly limited by the amount of B12 or stomachs make.  However, with one injection our B12 levels can be elevated for up to 4 weeks, and optimized for 1 week.

Not all types of B12 are created equal!

B12 is called cobalamin, and there are 4 variations of B12 each is named by how that cobalamin is bound.

  • Cyanocobalamin is the most common B12 offered in a pill or an injection.It is also the version used in food fortification.  Cyanocobalamin is the synthetic and manufactured version of B12.  It is used because it is the most stable version of B12 that has the longest shelf life.

  • Hydroxocobalamin is a naturally occurring version of B12 and is a more activated version that cyanocobalamin.Drawbacks to this version is that injections can be more painful.

  • Methylcobalamin is a naturally occurring B12 and the most activated version of B12.When injected in the muscle methylcobalamin can be slightly painful.Methylcobalamin is an excellent choice for smokers who are unable to convert cyanocobalamin to methylcobalamin, it is also a good choice for persons with known MTHFR mutations at the C677T and A1298C genes.

  • Adenosylcobalamin is another naturally occurring and activated version of B12 that is not available for injection.
