B12 is an extremely complicated issue.

Here is a starter article

https://www.mcpiqojournal.org/article/S2542-4548(19)30033-5/fulltext

I had a blood test that came back with segmented neutrophils. I would not have known this if I had not got a copy of the tests. My B-12 is at the “accepted” level of US Norms. Pathologist had recommended expansive B-12 testing but I guess Doctor missed that note because it wasn’t ordered.

I got the B-12 shots with arsenic in it which is what is given in the US. I think I need the version given in other countries.

But the point to my post is there are a lot of genetic factors that go into this..such as defects in the MTHFR gene

There is A LOT of discussion about B-12 on reddit. I found it helpful in trying to figure out what B-12 version would be right for me.

I have problems with dizziness and have gone through more testing than a great many of you due to rare issues. Mega dosing with b-12 helps me when I start getting more episodes of this but it is not directly related to b-12 issue. It just helps. Some B-12 is not right for me and that is due to genetic reasons. I red flag on my genetic tests for problems processing b-12.

These issues are far too advanced for my Doctors to understand so I had to try to figure this out myself.

Not one single Doctor figured out that I have calcified ligaments in my neck. Even radiologists missed it. It took a dentist who had seen it before to figure one of my problems and a neuroradiologist who knew what he was doing.

Tapeworms and other parasites in the body compete for the B-12 and can also create a B-12 deficiency that can lead to Megaloblastic anemia.

Megaloblastic anemia is a type of vitamin deficiency anemia that happens when you don’t get enough vitamin B12 and/or vitamin B9 (folate). It causes red blood cells to not fully develop causing hypoxia..

"education"?

Have you been schooled in B12? Classes now forming.

Or you need a different version of b-12 because of your genetic makeup - or it could be heart attack and genetics.

In my experiment with trying to find out what B-12 would work for me there was one that did cause chest pain and other heart related issues. Although, because I have silent reflux perhaps it was the b-12 reacting to that in addition to other things.

Silent Reflux can cause chest pain.

Right now I am trying out liquid B-12.

I don’t remember what I was trying last time I wore a heart monitor but this time I was pressing the button on it a lot less.

Did they give you Gabapentin? It is a neural blocker. Doesn’t solve the problem, but gives some relief.

I’m puzzled as to why they don’t sell an enteric coated B-12 tablet.

I think I just explained the absorption process in my previous post.

I'll have to sign up. I've never had a B12 shot. Does that come with the program or is it extra?...

WARNINGS about B12

ConsumerLab.com notes that a large study in the Netherlands found that people age 65 and older who took 500 mcg of B12 and 400 mcg of folic acid daily for 2 to 3 yrs. had a 77% higher risk of colorectal cancer than those in the placebo group, and an overall cancer rate 15% higher than those in the placebo group.

https://aacrjournals.org/cebp/article/28/2/275/71897/Folic-Acid-and-Vitamin-B12-Supplementation-and-the

A study of middle-aged men found that those with B12 blood levels above 455 pg/mL had an 85% higher risk of dying over the next 8 years, compared to men with blood levels below 339 pg/mL.

Great advice, thank you!

I’m not much of a drinker, so good there. I also don’t take antacids, so good there too.

My older sister has been getting B-12 shots monthly for a few years. It helps her depression some, but not much. (She’s really bipolar, but, to my knowledge, only sees her general practitioner, so she’s not being treated for bipolar, just depression.)

Just a few weeks ago, her husband was found to have low B-12 levels, so now he’s going to start getting the injections also.

From AI...

“The effectiveness of oral vitamin B12 compared to injected B12 has been a topic of research, and here’s what the findings suggest:

Similar Effectiveness: Low-quality evidence indicates that oral and intramuscular (IM) vitamin B12 can have similar effects in normalizing serum vitamin B12 levels.

Dosage Matters: Some studies show that high-dose oral B12 (around 2,000 mcg per day) can be more effective than intramuscular injections of 1,000 mcg per day for increasing vitamin B12 levels.

Neurologic and Hematologic Response: Research indicates that high-dose oral B12 is as effective as IM injections in achieving neurologic and hematologic responses.

Compliance: Oral supplementation can be just as effective as injections, provided there is adequate compliance with the dosage.

In summary, while both methods can be effective, oral B12 may offer a more convenient and cost-effective option for many people. “

B12 only does the body good when injected


That’s what I was taught, but apparently it’s not so. Here’s a study about it:

With so much garbage supplements out there, what is the best oral way to get the b12 ?

Brand ?

Some of what I see that lists the b12 ingredient also lists some xxx acid supplements in the same tablet.

I read that many a time the acid is what destroys b12 in the stomach.

Real don’t trust anything anymore.

That AI article is total BS as there are normally additional factors that require injections.

The topic is complex and an AI summary is dangerous.

It’s like saying that drinking water is better than an IV for increasing fluid in the body.

While generally true, there are specific reasons for an IV.
