Hello, I’m wondering if this might be the answer to some of my lingering symptoms some of which are neurological.
I’ve always had high levels of B12 in all my Medichecks blood tests. I’ve been hypo for decades and have now settled on 40mcg of T3 split over 2 doses daily and test twice a year.
I have problems however with strange nerve pains in my face, arm and back linked to chemical sensitivities. I also frequently have an enlarged tongue with teeth indentations all around. It’s often red & inflamed too.
My memory is not good and I sleep badly, waking much too early most nights.
I have awful digestion with IBS. I follow a restricted diet avoiding foods that cause me pain. I’m gluten, dairy and FODMAP free. Low acid problems I think. I take digestive enzymes now.
I know that digestive problems are known to cause B12 deficiency due to malabsorption.
I’ve been reading up & wondering if my high levels of B12 are masking a deficiency and giving me symptoms.
Does anybody know if it’s best to inject B12 to counteract this? I’ve used B vitamins supplements for years although usually keep them at a low level because of the high B12.
Do I need to take extra B2, folate, selenium & molybdenum as I’ve seen suggested as treatment? Is this something I can treat myself or should I find somebody to work with? Can I buy injections for myself? Which tests should I do to monitor?
Sorry for all the questions but all I’ve found online so far are academic papers full of chemistry.
Thank you for any help. I’ll try the Pernicious Anaemia forum too though I get the feeling this isn’t really their area.

Have you also tested key vitmins ferritin, folate, D3, if so what were the results? We need ALL of these vitamins to be at OPTIMAL levels for our thyroid hormone to work well.
thank you for reply. I have tried various probiotics without great results. My stomach is much more settled now but I think there might still be low acid & malabsorption. I’ll find my latest Medichecks results.
Having pernicious anaemia some of those symptoms are as you describe typical B12 deficiency but also other things too, but if levels are high this shouldn’t be the case. Firstly do you know what test you’ve had for B12 active or total. NHS predominantly do total (in my area anyhow) so total will show what level is there in your blood but not necessarily what is actually doing you any good, but you’d hope having high levels some is getting through but maybe not the case.
Digestive upsets, metformin and antacids, poor diet,over cooking and alcohol are some areas that can cause our B vitamins trouble along with stress.
I think it’s a trip to the GP and hopefully they’ll look at folate (B9) too and maybe see a dietitian/nutritionist as such dietary restrictions could be causing other problems if not supplementing and maybe wise to get some expert advice on how to overcome these (if any) with correct doses personally to you.
hi, I take 2 doses of T3 a day. Ferritin & B12 are over range at Medichecks & have been for years, probably inflammation. D & folate are mid range at Medichecks.
Thank you for your reply. I think my problems are not now hypothyroidism except for my low stomach acid. I might try some injections to see if they help. Nothing ventured, nothing gained!
I have a very high (over the range) B12 result most times I test it.
I discovered a few years ago that by keeping it at that level I fix a couple of health issues I've had most of my life.
I make sure I always take a B12 supplement (1000mcg) that is one of the active ones i.e. methylcobalamin and (sometimes) adenosylcobalamin. I take this about 3 or 4 days a week.
I also do my best to keep my folate quite high, while keeping it in range, although it has a tendency to drop frequently. I use methylfolate (1000mcg) for that. I take this about 3 or 4 days a week.
I also take a B Complex daily to cater for the other B vitamins.
One of the most likely reasons for me needing these high doses is because I have to take PPIs which cuts absorption of everything I take.
Thank you. I’ll try out some supplements to raise levels. I’ll also look at injections to avoid stomach absorption problems. It looks as if high levels aren’t the problem I thought they were.
You might want to look into h plyori, sibo and gut dysbiosis. Also have you ever had a sleep study done?
B1(Thiamine HCL) helps with digestion and acid production. Start low and slow if you decide to try it. Make sure you're taking a good b complex, I like Thorne Basic B. The higher you go with B1, you're going to require its co factors ( b complex, magnesium and potassium) I like to get my potassium from food sources like coconut water. It's great for the adrenals as well
I tried 100mg and it caused me to produce too much acid. That said, I absolutely loved how it made me feel energy wise. I dropped down to 50mg and I still was getting reflux in my throat. Dropped down to 25mg and still felt it gave me reflux. I'm thinking of either trying other forms of B1 or retrying it after I do a round of herbal antimicrobials for my SIBO.
****I have a hiatal hernia so I'm sure it might be contributing to my reflux *****
My B12 is also elevated without supplementing. I am wondering if I have a genetic tendency towards this. I will do a Lifecode GX Methylation report to see what's happening. Every time I see the GP I get asked about this and taking any supplements further raises levels but so farh hasn't provided me any benefit that I've ever noticed.
The activation and reactivation of B12 also requires other cofactors (vitamins and minerals), even if you supplement directly with an active form (as it will become inactive, and much of the benefit is from the ability to reactivate). Hopefully the Methylation test will present the genes in this context, including genes that impact the cofactors. It is possible that insufficiency of some cofactors are impacting the ability to utilise the B12 for other individuals too like yourself.
Yes Serendipitous, that’s very much the area I’m interested in.
I’ll have a look at the test you mentioned. I’ve done so much to try & sort my health out & have made progress but something is still giving me problems that are resistant to all that I’ve done so far.
Mainstream medicine is not helpful nor the very expensive functional medicine practitioner that I consulted. I’ll keep researching. I’d love to know how you get on.
The problem is this isn’t widely known and nutrigenomics is an emerging science. I don’t know who your FM practitioner is but it’s possible they weren’t trained in this. All the best.
I think I’m going to experiment with adding the appropriate supplements & not worry about getting a high level of B12. Hopefully some will make it through to my cells & if no improvement after a couple of months I’ll think again.

How many times were you tested before you got treated for your thyroid problem?
And they still Don't know how to treat thyroid!!!
How would I know if my levothyroxine dose is correct, my feet are so terribly cold as are my hands.
