How can one have proper B-12 in the serum with good CBC, but still be deficient? The answer is simple. There are 4 forms of b-12. The first form is cyanocobalamin which is usually found in multivitamins and can be toxic to people who do not have the ability to break down cyanocides which are toxic to the body. Second form is hydroxocobalamin which is the form which is preferred in people who have specific mutations. This form of b-12 can be broken down into the adenosylcobalamin or methylcobalamin. Adeno b-12 is used to drive mitochondrion function, CBC as well as to breakdown certain proteins. Adeno b-12 is also the form stored longest in the. Finally type of the most important b12 is the methyl b-12. This b-12 is needed to help methylate toxins from the body, formation of neurotransmitters, help cells communicate properly. Methyl b-12 is the shortest acting b-12 where as the longer active form adenosylcobalamin function can show up longer in the blood by representing the proper reading on a CBC. When a Dr looks at a CBC and see everything is normal this does not rule out a possibility of a methyl b-12 deficiency. Serum b-12 which are elevated when supplementation is not used is a representation of the body not being able to convert the b-12 into the proper forms. Elevated b-12 may also represent a Small intestinal bacterial infections.
