Vitamin B12

Also listed as: cyanocobalamin, methylcobalamin, cobalamin

What it is

A B vitamin needed for nerves and red blood cells. Cyanocobalamin is the common supplement form; methylcobalamin is a form the body uses directly.

Why it is in energy drinks

Added because B vitamins help the body release energy from food. It is not a stimulant.

Worth knowing

A B12 shortage causes tiredness, but extra B12 in people who are not short does not add energy.
