Best for Pernicious Anaemia Sufferers

Pernicious anaemia is an autoimmune disease which causes someone to be unable to absorb vitamin B12 from food. The body’s of those with Pernicious Anaemia produce an antibody which attacks the intrinsic factor protein needed for B12 absorption in the gut.

Treatment involves B12 injections to raise patients’ levels effectively. Sublingual sprays can be used to treat pernicious anaemia between these injections. While some patients manage perfectly well on an injection every twelve weeks, most of the members of the Pernicious Anaemia Society feel a return of their symptoms long before their injection is due.

The best B12 supplement for those with Pernicious Anaemia is our Boost B12 Oral Spray which delivers a high-dose of 1,200μg for optimum absorption between injections. 

Always consult your doctor before taking supplements in an attempt to help support your Pernicious Anaemia, and ensure you continue to act upon the advice of your healthcare provider. 

How Much B12 Do You Need Daily?

Once you have the best B12 supplements for you, you’ll need to know how much B12 you need per day

According to the NHS, the recommended daily dosage of vitamin B12 is 

  • 1.5μg (micrograms) per day for adults aged 19 - 64.

When supplementing, you should pay attention to nutrient reference value guidelines, and stay within the safe upper limit. This is the maximum amount to ensure you do not exceed what is healthy. With B12, there is no safe upper limit because it is a water-soluble vitamin, so any excess will exit the body through the urine.
