There are four types of B12: adenosylcobalamin, hydroxocobalamin, methylcobalamin, and cyanocobalamin.
<ul>
<li style="font-weight: 400;">Adenosylcobalamin: A primary form of B12 in the body that is mostly concentrated in cellular tissues.</li>
<li style="font-weight: 400;">Hydroxocobalamin: Supports natural detoxification pathways and easily converts into methylcobalamin, the most active form.&#x2020;</li>
<li style="font-weight: 400;">Methylcobalamin: A primary form of B12 in the body that is mostly concentrated in blood plasma.</li>
<li style="font-weight: 400;">Cyanocobalamin: None of our products contain this form. This is the inactive form that is paired with a cyanide molecule and is the most difficult to absorb and use in the body.</li>
</ul>
Your healthcare provider will be the best person to determine which form(s) are optimal for your health needs.
