This vitamin is produced naturally by bacteria, and is necessary for DNA synthesis and cellular energy production. Vitamin B12 has many forms, including the cyano-, methyl-, deoxyadenosyl- and hydroxy-cobalamin forms. The cyano form, is the most widely used form in supplements and prescription drugs,.  Several pharmaceutical forms of cyanocobalamin have been developed, including the tablet, injection, and nasal spray forms,,.  This drug was initially approved by the FDA in 1942."}]
