For individuals with low B12 levels or those who have difficulty absorbing B12, more frequent injections may be necessary to maintain optimal levels
Because of that, the NICE recommendations lean towards individualised care: tailoring the dose, frequency and delivery method, following people up at around three months, and reviewing sooner if symptoms are severe or if someone is pregnant or breastfeeding
This ensures that B12 is the right fit for your current needs
However, B12 injections are not a treatment for insomnia, depression, or anxiety on their own
The 2024 NICE update was explicit on one point: do not rule out B12 deficiency just because the standard blood count looks normal
