Vitamin B12 is a collection of molecules found in the body.

It is normally involved in the metabolism of every cell of the body, especially affecting the DNA synthesis and regulation but also fatty acid synthesis and energy production. A deficiency in B12 can also result in varying degrees of neuropathy, nerve damage that can cause tingling and numbness in the patient’s hands and feet.
