Cyanocobalamin

<p><b>Cyanocobalamin</b> is the most common and widely produced of the chemical compounds that have vitamin activity as <a href="http://en.wikipedia.org/wiki/Vitamin_B12" title="Vitamin B12">vitamin B₁₂</a>.&nbsp;</p>

<p>

Vitamin B₁₂ is the "generic descriptor" name for any of such <a href="http://en.wikipedia.org/wiki/Vitamer" title="Vitamer">vitamers</a> of vitamin B₁₂.&nbsp;</p>

<p>

Because the body can<sup class="Template-Fact" >[<i><a href="http://en.wikipedia.org/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed">citation needed</a></i>]</sup> convert cyanocobalamin to any one of the active vitamin B₁₂ compounds, by definition this makes cyanocobalamin itself a form (or vitamer) of B₁₂, albeit a largely artificial one.</p>
