We know you probably have many concerns about the tablet vitamin B12 but there is good evidence that the human body can cope adequately without B12 top ups in any form (injection or tablet) for a period of time.
When you first started having vitamin B12 injections you will have started with 6 loading doses, half of which will have been stored in the liver.
The subsequent top up doses every 2-3months are simply precautionary to stop the levels dropping again.
All people currently prescribed injectable B12 will have enough to carry them through the next few challenging months but we are issuing tablet B12 to ensure levels stay steady; this is true of all patients with previous B12 deficiency including Pernicious anaemia.
One of the things people with Pernicious anaemia worry about is that they cannot absorb the B12 through the supplements alone but there is 5% of B12 which is absorbed in different ways in the body not just through the digestive system.
So since we are simply keeping the levels topped up, this additional 5% absorption is enough for maintenance therapy until we start seeing you face to face again when it is safe to do so.
