Female, 50s. I've had brain fog, depression, anxiety and other symptoms for years. Every doctor tells me I'm Vit B deficient. When I try to supplement, it gives me anxiety. I've tried methylcobalamin pills and lozenges and sublingual, and am now trying hydroxocobalamin lozenges for the first time, but I already feel the anxiety creeping in. I have gut issues (IBD) and the MTHFR gene mutation so my functional doctor suggested I try injections next. Have you been through this journey before and found injections to be beneficial? What effect should I expect from the injections? Is there something else I should be doing to improve my Vit B levels? Really at the end of my rope, and having brain fog/anxiety makes it so hard to figure out a way forward. Thanks. |
Have you tried to fix your IBD with your functional med doctor yet? I am assuming that losing nutrients due to gut issues may be the issue, and you probably could be getting way more vit B from food without IBD. Have you addressed that through diet, etc yet? |
i like the b12 gel tablets |
I loved the injections. I was actually hoping to continue them but I have intrinsic factor and stabilized so my doctor stopped prescribing them |
I just go to urgent care and pay $40 for an injection. I go once a month. Insurance probably would cover it if I got it through my dr but the hassle of making an appointment, driving there and back makes it not worth it.
I was severely B12 deficient and don't absorb it well through the gut. The shots have been life changing. |
WHY are you only supplementing one B vitamin? Doing that causes other deficiencies, imbalances, and all sorts of problems. Only take a pill that contains all 11 B vitamins. ![]() |
That’s not necessarily correct advice |
Why are they approaching this as a “vitamin deficiency” instead of tying the brain fog and anxiety to your autoimmune condition? |
Have you ever just taken a once a day without iron like CVS sells? Does that make you anxious? |
Vitamin b12 deficiency is quite serious.
Longterm it can cause all kinds neurological issues including memory deficits akin to dementia. I recommend you talk to your doctor and make a plan. The plan absolutely has to include normalizing your b12 if you want to prevent serious problems. Injections are a good idea but talk to your doctor. |
Which urgent care do you go to that does that? |
You need to go to your primary care and get a blood test. Your primary care can do the shots but I found a high dose of b12 pill worked best but you need to consult with your doctor not internet. |
I’d ask for a complete iron panel testing your ferritin and iron saturation, in light of your issues. Anemia can also cause brain fog. |
Thanks to the two posters who actually tried to answer the question.
To the person who does the $40 urgent care shots, can you please tell me a bit more how the shots have been life changing and what short and long-term effects you've noticed? To the person with the intrinsic factor, why were you taking the shots originally and what effects did you notice? |
What is intrinsic factor and why did it make you stop the Vitamin B? |
