Vitamin B12 Deficiency

Vitamin B12, also called cobalamin, is a water soluble vitamin with a key role in the normal functioning of the brain and nervous system.

Vitamin B12 deficiency: Common early symptoms are tiredness, a decreased mental work capacity, weakened concentration and memory, and irritability and depression. If left unchecked I believe that this deficiency can lead to Depersonalization. I recently just got a blood test done for something unrelated and it to showed that I was low on this vitamin.

People who have this problem due to an absorption problem (as opposed to simply having a diet that's lacking in B12) won't benefit from multivitamins containing the B-complex. To sum it up, if a person is 1.) deficient and 2.) the deficiency is due to malabsorption or a similar breakdown in B12's metabolism, that person needs injections and/or oral (or sublingula lozenge) therapy--possibly lifelong. It can take a long time--decades, sometimes--for B12 deficiency to develop.

A simple bloodtest should be able to tell if you are low on this vitamin so it isn't difficult to check (Might aswell just to make sure that this isn't the cause) but don't let your doctor tell you that you can't be B12 deficient because you're not anemic; symptoms (neurological symptoms especially) often show up a long time before the deficiency manifests itself as a blood disorder.

For me personally I am to start getting monthly injections of this vitamin on Monday. I will reply to this topic if my DP improves over the coming few months.

Simple fix: B12 and folate supplement. Fixed me right up and it has not been an issue since.
Are you saying B12 and folate cured your DP?
diagnosed with deficiencies in vitamin D, iron and B12 8 months ago (late June 2022). Diagnosed with depression & anxiety in 2019, but I think I've been disassociated since anywhere between 2018-2021. Zoloft didn't really work for me (because of B12 deficiency). Been on injections since June 2022, every month and at the start of this year, every 3 months. I still feel like I'm on autopilot, like these words aren't mine, like the only thing I'm actively controlling is my eyes but everything looks and feels weird. Worried that my B12 deficiency has caused eye problems or nervous system damage, and not sure if there's any way of knowing. Got a test the other day and levels are still low so still going to have injections. Don't know why it's low, I've been having an egg on toast every morning to try to get it up. Energy levels are definitely better, but I still feel very foggy, numb and burnt out. Will keep updates if I remember, but feel like I've lost all hope in "feeling" alive and present and just want to get back to how I was and have answers.

Update on this please? Did it work?

Unfortunately not entirely. I feel more energetic, but no improvement in feeling more "present". I do notice when my levels get low as I suddenly crash and get depressed, but overall still feel foggy so it's likely something else provoking my DPDR.

Also started taking 5-HTP before I go to sleep and haven't noticed any change, but it's only been a few weeks.
