Order a Vitamin B12 blood test online. Quick, private at-home kit to check deficiency, fatigue, anaemia & energy levels. UK accredited lab testing.
The Vitamin B12 Blood Test from Repose Healthcare provides a simple, accurate, and private way to measure your vitamin B12 levels without visiting a GP or clinic. Vitamin B12 (also known as cobalamin) is essential for red blood cell production, nerve function, brain health, and energy metabolism.
A deficiency in vitamin B12 can lead to fatigue, weakness, anaemia, memory problems, and neurological issues if left untreated. With our convenient at-home finger-prick blood test, you can quickly assess your vitamin B12 levels and take steps to improve your health.
Vitamin B12 is a water-soluble vitamin that plays a crucial role in many bodily functions:
Red blood cell formation – prevents megaloblastic anaemia
Nervous system function – supports healthy nerves and myelin
Brain health – linked to concentration, memory, and mood regulation
Energy metabolism – helps convert food into usable energy
DNA synthesis – vital for cell repair and growth
Since vitamin B12 is not naturally produced by the body, it must come from diet or supplementation.
Deficiency can develop gradually and cause a wide range of symptoms, including:
Tiredness, weakness, and fatigue
Pale or jaundiced skin
Numbness or tingling in hands and feet
Poor balance or coordination
Memory loss or difficulty concentrating
Low mood, irritability, or depression
Sore or swollen tongue
Shortness of breath and palpitations
Megaloblastic anaemia in severe cases
You may benefit from testing if you:
Experience unexplained fatigue or low energy
Have neurological symptoms such as numbness, tingling, or poor balance
Follow a vegetarian or vegan diet (B12 is mainly found in animal products)
Are pregnant or planning a pregnancy
Are over 50, as absorption decreases with age
Take medications such as metformin, proton pump inhibitors, or anticonvulsants
Have digestive conditions like coeliac disease, Crohn’s disease, or pernicious anaemia

Your test results will indicate if your B12 levels are:
Low (deficient) – may cause anaemia, nerve damage, and cognitive problems
Borderline – could suggest inadequate absorption or dietary intake
Normal – within the healthy range for your age and gender
High – often due to supplementation or, in rare cases, other health conditions
We provide clear explanations and guidance to help you take the next steps for your health.
If left untreated, low vitamin B12 levels can contribute to:
Megaloblastic anaemia – large, immature red blood cells that can’t function properly
Neurological damage – nerve pain, numbness, and balance issues
Cognitive decline – memory loss, confusion, and difficulty concentrating
Mood disorders – including irritability, depression, and anxiety
