Vitamin B12 is an important vitamin, essential for the normal functioning of many body processes. Deficiency can lead to anaemia (poor quality red blood cells) and neurological (nerve) disorders. It is most abundant in meat products so vegetarians are more vulnerable to deficiency of this vitamin.
Pernicious anaemia develops if uptake of vitamin B12 into the blood from the gut is absent or severely impaired, and even if a diet rich in the vitamin is taken, deficiency will occur if this disease is present. Recent evidence suggests that mild deficiency is probably more common than previously thought. Mild deficiency may explain the presence of fatigue and a host of other limiting symptoms.

Utterly patient, kind and helpful, kit arrived next day, as did my results. 5 stars well-deserved.UK
Great service and product. The turn around is brilliant (mostly - there was a glitch during the early part of the Covid pandemic, but that seems to be resolved now). Tests are recognised by the medical profession so I am able to use the results to get the treatment I need without further tests.UK
I had various questions which they answered via email/webchat and the timing of getting a kit, sending it back and getting the results was good.UK
