Who Is At Risk?
They can range from fatigue and confusion to anemia or a compromised immune system. Skin rashes also can occur.
How Much To Get?
1. Fatigue
Your body’s cells need B12 to function properly.
This condition leads to the formation of large, abnormal, and immature red blood cells and impaired DNA synthesis When your body doesn’t have enough healthy red blood cells to carry oxygen to tissues, you’ll likely feel weak and tired.

B12 or folate deficiency anaemia can cause a wide range of symptoms.
Anaemia is where you have fewer red blood cells than normal or you have an abnormally low amount of a substance called haemoglobin in each red blood cell. General symptoms of anaemia may include: extreme tiredness (fatigue)
lack of energy (lethargy)
breathlessness
feeling faint
headaches
pale skin
noticeable heartbeats (palpitations)
hearing sounds coming from inside the body, rather than from an outside source (tinnitus)
loss of appetite and weight loss
Symptoms of vitamin B12 deficiency If you have anaemia caused by a vitamin B12 deficiency, you may have other symptoms, such as: a pale yellow tinge to your skin
a sore and red tongue (glossitis)
mouth ulcers
pins and needles (paraesthesia)
changes in the way that you walk and move around
disturbed vision
irritability
depression
changes in the way you think, feel and behave
a decline in your mental abilities, such as memory, understanding and judgement (dementia) Some of these symptoms can also happen in people who have a vitamin B12 deficiency but have not developed anaemia.
