Vitamin B12

Vitamin B12, also known as Methylcobalamin or cyanocobalamin, is an essential B vitamin for the body. It is necessary for making red blood cells, which makes it important for people that suffer from anaemia, or that don't eat meat. Vitamin B12 is also important for our nervous system as it helps to insulate certain nerve fibres to protect them from damage. Vitamin B12 deficiency symptoms include dizziness and fatigue.
