There are four types of B12 (“cobalamin”) you’re likely to see in supplements:

•  Cyanobalamin: synthetic version; used least efficiently by the body
•  Methylcobalamin: an active form (meaning, ready to be used by the body) of B12 that supports the methylation process
•  Adenosylcobalamin: another active form of B12 that primarily supports mitochondrial function and metabolism 
•  Hydroxocobalamin: the predominant form of B12 found in foods, a precursor to the active forms of B12

This unique blend of adenosylcobalamin and hydroxocobalamin supports nerve and mitochondrial health.
Adenosylcobalamin is the major form of vitamin B12 stored in the mitochondria of cellular tissues, and is a key factor in carbohydrate metabolism. Optimal levels also support healthy synthesis of neuronal myelin, the protective sheath that protects nerves throughout the body.

Benefits of Vitamin B12

• Nerve health and protection: vitamin B12 is required for the body to produce and maintain the myelin sheath, the fatty protective layer that insulates nerves.
• Reduces homocysteine: if too concentrated in the blood, the amino acid homocysteine may contribute to chronic diseases, including cardiovascular disease; the body needs adequate B12 to convert homocysteine into a form that the body can use.
• DNA republication: without enough B12, bone marrow cannot produce enough DNA to produce white blood cells, affecting susceptibility to infection
• Supports cell and tissue growth
• Stabilizes cell membranes, allowing hormones to be used in the cells rather than staying in the bloodstream
• Needed for the body to produce healthy red blood cells
• Plays a key role in the Krebs Cycle for proper metabolism
• Helps to maintain a balanced immune system
