Vitamin B 12 (Cyanocobalamin) is a chemical that comes, mainly, from red meats, dairy and eggs. 


This important vitamin plays role in synthesising human DNA, fatty acids and myelin. It is pretty obvious to everyone that DNA is a building block of our body. Without constant synthesising of DNA, our body would die pretty soon. 

Fatty acids are important in many processes in the body including the production of hormones.

Myelin is an outer layer of nerves. Without healthy myelin nerve signals cannot pass through the nerves properly. That causes all sorts of health problems including dementia, weakness, ageing and many many more.


The signs of Vitamin B12 deficiency are:

  • Pale or yellowish skin
  • Constant fatigue
  • Pins and needles felt around the body
  • Poor mobility – a person deficient in B12 becomes slow and clumsy
  • Mouth ulcers 
  • Dizziness and shortness of breath
  • Blurred and disturbed vision
  • Mood changes

Astonishingly 40% of people are Vitamin B 12 deficient.

Vitamin B12 should be tested along with Full Blood Count and Folic Acid.
