WHY VITAMIN B12?
o After water and oxygen, vitamin B12 is the next essential micronutrient molecule vital for health o Vitamin B12 deficiency is common and can manifest at any age and is largely unrecognised o Vitamin B12 is crucial for many systems of the body to function correctly o Pernicious anaemia is just one illness related to a deficiency in vitamin B12 o It is believed that vitamin B12 deficiency is not always detectable on blood tests o Symptoms such as depression, anxiety and psychosis as well as the early onset of dementia are common with vitamin B12 deficiency o Causes of B12 deficiency include genetic disorders, poor diet, gastrointestinal illness or surgery, alcoholism and use of antacids o Vitamin B12 is non-toxic – even at really high doses
Vitamin B12 is absorbed into our tissues through the digestive tract, however this process can be disrupted from poor digestion, intestinal disease or the use of some medications etc. Main causes are due to atrophic gastritis and lack of Intrinsic Factor (IF), a glycoprotein produced by the stomach that is required for the absorption of B12. As well as from poor diet and digestion, vitamin B12 deficiencies can also be affected by a genetic condition such as:
o Pernicious anaemia o Crohn’s disease o Treatment with proton-pump inhibitors o Atrophic gastritis o Coeliac disease o Use of antacids (acid is required to release B12 from food) o Gastrointestinal surgery o Use of certain medications o Use of illegal drugs and substances including nitrous oxide
A loading dose of injections is often recommended for those with a deficiency. This is an injection each week for 4 weeks and then a monthly injection after.
o Pains in hands and feet remit
o Strength and grip improve
o Cyclical hormones such as fertility cycles normalise
o Thyroid and cortisol hormones normalise
