FAQs

B12 is a key vitamin we get from our diets. It’s needed for a bunch of bodily functions, including red blood cell production, tissue and cell division, and nerve health.

Vitamin B12 deficiency is common, even though it’s naturally found in many animal foods like meat, fish, eggs and dairy. That’s why if you’re a long-term vegan or vegetarian, you may wish to check your B12 levels regularly.

But you don’t just have to be a vegan or vegetarian to be deficient in B12. If you have any symptoms such as tiredness, low energy, mouth ulcers, breathlessness, headaches, these may be a sign of B12 deficiency.

 

When you have low vitamin B12 levels, you may get the following symptoms:

  • tiredness
  • headaches
  • low energy
  • breathlessness

    If your B12 levels are particularly low, then mouth ulcers, pins and needles, and extreme tiredness are common. Keeping track of your levels could prevent any long-term damage to your body.


    Talk to your doctor before taking this test. Being pregnant can have a noticeable impact on your results, so make sure to check in with your GP first.
