B12 is the most chemically complex of all vitamins, and is essential in making red blood cells, nerves and DNA. It is water soluble, which means it can dissolve in water and travel through the bloodstream. However, as it is not created by the body, it needs to be a consistent part of our diet to make sure we’re getting enough.

It is also known as cobalamin. Fun fact: The word cobalamin is a combination of the words ‘cobalt’ and ‘vitamin’ as B12 contains cobalt, an essential trace element, right in the middle of its structure. That’s not vital information, but it will make you sound knowledgeable at parties!

What does B12 do for the body? 

B12 plays a number of crucial functions in the body: 

  • Supporting metabolism: The metabolism of every cell depends on B12. Take your red blood cells for example. They are vital in transporting oxygen and iron around the body, and we produce millions of them every minute. B12 helps these cells to multiply correctly, and without a sufficient amount, their levels drop, which can cause anaemia. 
  • DNA production: It is also vital in the production of our DNA, and ensures the proper functioning of our nervous system. It does this by maintaining the myelin sheath, a substance which covers the nerves of our central and peripheral nervous systems. 
  • Fueling the body: B12 helps the body to absorb folic acid, which is needed within the body for energy production and release, supporting healthy energy levels and reducing fatigue. This is extra important for those of us living a very active lifestyle, as I’m sure you can imagine!
  • Boosting immune system: It supports your immune system by playing a role in white blood cell production and contributes to healthy brain function. Age related memory decline has been linked with lower levels of vitamin B12 in the brain. 
  • Fighting disease: B12 also plays a role in regulating the body’s levels of an amino acid called homocysteine. This particular amino acid is associated with Alzheimer’s, Parkinson’s disease and cardiovascular disease, so keeping it well regulated is very important. 
  • Keeping you happy: Finally, because we all love a mood booster – regular B12 supplements have been shown to increase your mood, and reduce the symptoms of anxiety and depression. 

 How much B12 do you need per day? 

The Recommended Daily Amount of B12 is between 250 – 500 mcg per day for adults. Vivo Life’s liquid B12 supplement contains 500mcg per serving of the three most active forms of B12: Methylcobalamin, Hydroxocobalamin and Adenosylcobalamin. Try saying any of those 10 times fast!
