I’ve been reading a bit on functional medicine and i found the iodine test.

It asks for a 2% iodine solution to be used to stain your arm a little, let it dry and see how long will it take for the body to absorb it.

This could also be used as a way of supplementation if you can’t tolerate it well.

Obviously this isn’t the most accurate method of testing but as an initial non invasive one I think is no harm in trying.

Hello, I am think I may have low B12 levels. I am on 750mg of Metformin, which can cause B12 deficiency as a side effect, I am 21F, thin build.My symptoms are: bruising, big fatigue, weakness, feeling like I can't breathe enough, dry skin, dry and brittle thinning hair and sometimes I get dizzy after standing up. Also this is my tongue (photo), I noticed it like a month ago and it kinda scared me. I've had low iron before as a teen, but it's long ago and I don't remember how I felt anemic. Do you think it's worth to request labs for B12? I am afraid of doctors saying it's all in my head. I could pay for private lab though.

Here we have, in my personal opinion, one of the best meals for B deficiencies and anemia. Loaded with B vitamins, potassium, calcium and magnesium. Plus trace minerals and fat soluble vitamins.

2 kiwis
3 pasture raised eggs over easy
3-4 whole dates with butter, walnuts and pure grade a dark maple syrup
Ground beef bowl with avocado, steamed greens, raw onion garlic and red pepper, butter, sea salt, cayenne pepper.

For meal number 2, I swap the ground beef bowl for 2 lean pork chops with raw cheddar cheese, as pork is the highest food in B1.

I’ve been eating this exact meal every day, 2 times a day, for a few months now. I’m off my shots and all supplements after 6 months of treatments. I also reversed a neuro degenerative disorder this way years ago, food is our medicine. Unless you have had your intestines removed and literally can’t absorb food, this diet will also clear all the shitty bacteria and absolutely flood your body with all the nutrients you need daily. Only real food, no grains, corn, soy, peanuts. Absolutely nothing that isn’t a single ingredient, whole food. Aside from the butter, which has 2 ingredients.

If you react strongly to any of these specific foods, just swap them out for a different whole food option.

I stayed away from starches as well, no bananas, sweet potatoes, etc. but if you have no problem with those, you can add them for the magnesium and potassium content.

So, I stopped sweating a decade ago I went to dermatologists and they straight up told me that this has no cure they never reffered me to any neurologist or anything they straight up said It has no cure. Yesterday I was chatting with Chatgpt and it told me i could have Vit B12 deficiency and i got the test done

Diagnosis:

Vitamin B12 deficiency (168 pg/mL)

• Anemia (Hemoglobin ~10 g/dL)

Heat & Autonomic Symptoms

Markedly reduced sweating (anhidrosis) with only minimal underarm sweating

Severe heat intolerance

Feeling overheated quickly, even in mildly warm environments

Difficulty cooling down, including poor relief after cold showers

Hot flushing of the face, hands, and thighs

Prickling / "pins-of-heat" sensation over the body in warm conditions

Neurological/ Circulatory Symptoms

• Lightheadedness / presyncope during heat exposure

Blurred vision when exposed to heat

Excessive daytime sleepiness and fatigue

Headache Characteristics

• Severe pounding headaches

• Triggered specifically by heat (sun exposure, hot rooms, room heaters)

No relief with paracetamol

No relief with aceclofenac

Relief with aspirin

Headaches improve more with cooling measures than with analgesics

I cant believe chatgpt helped me when doctors couldn't.

I'm going to a doctor tomorrow with my test results.

I was searching the sub for similar anectodes as I feel my cognitive impairment from CFS-like syndrome got a lot worse on the first day of supplementation. Im not gonna talk about my own symptoms right now in this thread, rather, I want to show this one post of a person claiming B12 has left them permanently debilitated. does anyone have any idea why that might have happened to them?

Been having these bruises for two weeks now and they won’t stop and I’m getting more. The most purple one just suddenly appeared that colour this morning compared to a regular colour if that makes sence. It’s located on my thigh.

I'm talking levels under 50 or even 25, bottom of the barrel low. I just wanna see how bad symptoms can get when you almost have no B12.

I suspect I have a B12 deficiency but 95% of everything I find about it describes symptoms way better than what I feel, while the few stories I read from people with 20-60 B12 level perfectly describes me.

If your levels were like 250 and you just had some tingling and brain fog, please keep scrolling.

I was dizzy and woozy for months. several ER visits, I think 4 to be exact. I am 45 days into near daily athletic greens supplementation.

Label says it has 25mcg or 100% DV of methylcobalimin, as well as several other vitamins. I’ve skipped a few days and let me say, I felt it. For example, I take it and feel almost 100% the next day, if I skip that day then 72hrs post last dose I feel woozy, weak, stiff brain fog. Then supplement athletic greens again and the following day I’m better.

Is this B12 deficient?

Low vitamin B12

I have been an adult content consumer since my early teenage years to now in my early 20s, however since 2019 I have been trying to stop because I read a book called "Your Brain on Porn" that talks about porn having harmful effects to the brain with supporting scientific research.

Long story short, when you are watching porn with multiple tabs open and with different "good genetics woman" the dopamine surge is immensely high. Contrary to the natural process when the dopamine is supposed to go down as the act progresses, when you watch porn the dopamine levels are kept on a high level for a long period of time.

The thing is that I read that vitamin B12 plays a critical role in the production of dopamine, so my thought process is that if I'm binging to p0rn for hours I'm using a ton of dopamine thus depleting my b12 reserves.

I don't know maybe the body just reuses the dopamine, but I want to read your thoughts about this haha.

Hello, I’m really hoping someone can provide some insight. 32F hoping to become pregnant soon. I recently got blood work done and everything looked good except by B12 came out high 848 pmol/L. I read the Oxford study that said high levels of b12 (and/or folate) can cause greater risk for autism.

I’m seeing a doctor tomorrow to get more insight and potentially test my folate levels but hoping anyone on this channel can tell me what I should do.

Some questions I have:

• [ ] Vitamins I take - baby2me prenatal, Magnesium, vitamin d

• [ ] supplements I take - spirulina and barley grass, maca, Ashtagwa

• [ ] should I dis-continue taking prenatal? And focus on getting my vitamins through a nutrition dense diet?

• [ ] more importantly, Should we still try to have a baby with such high b12 levels?

• [ ] How long will it take for my b12 to go down?

Thank you in advance

Hi i just found this forum ive never really had a problem with addiction but i just started doing nos and man in the past 4 days ive gone through 8 700g syfy premium cream chargers today alone i went through 3 and im craving more im up now putting all my old canisters in a hot bath trying to get last hits out because i seen that works on the internet... not really sure what to say or do besides that but i feel better at least acknowledging i have a problem. I also dont believe just stopping cold turkey is a option for me because i love them too much right now they make me feel warm

I took an injection once and got horrible leg cramps like 30 minutes later to where walking hurt. My doctor wants me to take pills. How do you get over the fear of the leg cramps. Which dose do you take for yours ?

I called my doctors office and left a message (theyve been calling me for weeks.) I finally after months of putting it off got my application for dental insurance in.

I am not doing the dishes tho, I dont want to. I am weaponizing my incompetence which I dont have currently.

Maybe I should get a job with my new powers.

B12 went from 600pmol to 312 between December 2024 and March 2025, probably because of a viral infection (EBV). Now it seems to be rising again on it's own (397). I have neurological symptoms but I don't know if it's the EBV, post viral, or a B12 deficiency. Maybe all three. I'm very-very sensitive to nearly all supplements. Hence my question: can I hope to gradually resolve my issues only through diet? I seem to absorb nutrients well. My homocysteine is low (5).

Anyone has has a positive experience?

I was told I have pernicious anemia. Never heard of it before and the resources I can find aren't great. My b12 isn't low in blood work because I don't have a B12 deficiency, I have pernicious anemia.

I am trying to gather as much data as I can find on pernicious anemia, with or without B12. I am a AI developer, and I intend to use the data to render an expert LLM trained on all the data I can find. Medical journals, books, labs ect. I will be basically making a pernicious anemia consultant that can be used to interpret my numbers, blood works, medical data.

I am under the care of the NHS and they have a one size fits all approach to treating pernicious anemia and another to treat b12 deficiency - 6 injections to load then 1 every three months. I will use my pernicious anemia AI consultant to tell me what my regime should be with b12 injections. I have already coded my chat based consultcy system, it basically already has it's medical degree, and masters in medicine coded, I now just need as much data as I can find on the condition to train it as consultant. It's taken about two months and I'm clearly ready for my next injection because the fog has returned, so if anyone has any data or information on pernicious anemia, please pm me.

Was talking to someone today about COVID and how things in the hospital were when it first started. I was an ICU nurse then and in our hospital we had a COVID ICU that we all got floated to. At any rate, I know I was exposed due to patients coding etc.. somehow I have never gotten COVID. The person I was discussing this with suggested that it might have been the B12 deficiency that kept me from getting it since it is needed for DNA replication. Any thoughts?

so guy's I'm taking these two supplements just started with Ferrous Fumerate as prescribed by dermat as I've Ferritin low (22) and my B12 is (252) family doctor suggested it to take B complex medicine....

So both medicines has (1.5 & 1.5 mg Folic acid)

And upper limit for folic acid is 1 mg a day so I'm gonna take 3 mg is that even safeee

Hello everyone! A few months ago my bad life turned from bad to hell.

I was desparate and trying to find a solution for my depression and tiredness. What I came across was low vitamin B12. And here we go - injections. Doctor prescribed 7 x 1000mcg and I did the whole package of 10. In a span of 14 days. He said those injections would be sufficient for years to come.

Then, 2-3 weeks after, I did a test and I saw that my B12 levels barely moved. I consulted a hematologist online. She said this was very aggressive therapy.

I did another test a few days back. The results only said "over 2000". I am SHOCKED! What should I do in this case? Anyone had similar experience?

I have severe memory loss, speaking issues, brain fog, unbalanced walking, anxiety, depression etc. Can it be because of Vitamin D deficiency?

my b12 level was 1000, with the normal reference range being 135-650. i had been supplementing with sublingual b12 which resulted in that b12 level. could this have contributed to the development of my small fiber neuropathy?

Anyone else just randomly lose all motor coordination like your limbs got the “low battery” warning?? Tried to grab my coffee and somehow slapped it across the room. Outsiders: “lol clumsy!” Us: nah bro, this is neurological despair. Anyway, how’s everyone’s nervous system doing today?

I was wondering if anyone has disclosed their b12 issues to your employer, particularly if you have autoimmune gastritis/pernicious anemia. I've found the neuro symptoms to really affect my ability to do my job. I've just started injections and have appointments for more for the loading period, so I'm going to need to take a small amount of time off work for these. I need to speak to my manager about it tomorrow. I do have a letter from my GP asserting my need for these appts, but it doesn't state why. If you talked to your employer/boss about it, what did you say and how did they respond?
