I have a B12 test at the VA next week. Its going to be a serum b12 test. If I stop taking my 1 a day, and stop eating foods with folate, will that help the test come out correct? Sally's book says the serum b12 test is messed up by folate, as I remember from reading it. What else can I do to help the odds of a proper result? I've been a vegetarian 33 years, and Im 62 years old. I suspect I might be low. Jim

Jim If you have been a vegetarian for 33 years and haven't been properly supplementing you are deficient, no ifs, ands or buts about it. A one-a-day vitamin isn't going to do the trick. You are playing dangerous games with your health. Why wait for a test. You can start right away. The purpose isn't to prove to somebody that you are low by getting "proper" test results. No matter what the results are you should supplement. The results of the test are completely irrelavent. As a vegetarian you can't be anything but low if you haven't been taking b12. By next week you can know for sure by starting to get better. Why don't you come over to the b12 thread http://forums.wrongdiagnosis.com/showthread.php?p=144582&posted=1#post144582 and talk about it with other folks including vegetarians. The longer you wait the more damage you do.

  • Thanks Fedd, What I want is a TRUE BASELINE. So, as I am already scheduled for a fasting lab on the 18th, I called and asked for a B12 test. Doesnt look good for a uMMA, but I can get a serum b12 it seems. What about a Hcy homocysteine test? The book listed that test as another fool proof test. Should I ask for that? After reading part of the B12 book, I did start No Shot methyl B12, 5000mcg. I took one every 2 or 3 days. I did that for about 2 months. It is hard to tell about results. My thinking did seem more clear. After I quit the No Shot, maybe 1 week, I started feeling bloated after eating a small snack, like yogurt. After a real mean, even more bloated. I remember that from the B12 book. When I 1st turned vegetarian, I used to eat chicken, fish, and eggs. So I never worried about B12. 20 years later I quit eating those things, just cheese, and yogurt. After 10 years of a more strict diet, free of most animal foods, I found the b12 book, and it opened my eyes. Dont worry, I'm just trying to get a result I can "trust" with the serum B12 test. After that, I'll go back on No Shot methyl B12 sublinguals. So, does anyone know of any ways I can help the test results be true? I mentioned stopping the 1 a day, and No Shot, and I'm staying away from anything that lists folate. But Im afraid there is still folate in the flour, and its not listed as an ingredient. Isnt folate required by law in EVERYTHING? Thanks Jim

  • I'd like to know where I stand b12 wise for myself, by doing a B12 test. Plus my wife has been a vegetarian as long as I have, and has not shown any interest in taking B12. So if I can show my own deficiency, and be ordered by my MD to take B12, I feel it may push her to either be tested, or take B12. SOooo, I have this already scheduled fasting lab next week. I'll avoid any folate I can, and hope the serum B12 test gives a acurite result. I was wondering if by avoiding as much folate as possible, I can get a reliable serum B12 test result. And want to know what other things might skew the test next week? I'm going to call my nurse and ask if my doc will order a Hcy test also, the B12 book said the hcy test was some sort of backup to test for low B12. Jim

Jim Hi Sunwatt, Folate does not affect serum cobalamin level. Taking vitamin b12 in any form will raise cobalamin level as will any animal based food such as eggs, fish, milk, cheese, etc. All the folate in the world will not raise your cobalamin level. It could correct blood measurements such as MCV and MCH over a period of months without preventing neurological deterioration and metabolic deterioration. Hcy detects one defect caused by low methylcobalamin. uMMA detects one defect caused by low adenosylb12. In studies 2/3s of responders had normal test results when admission was based on symptoms rather than test results. If you are extremely fatigued uMMA is more likely to show high. Nothing but b12 in one form or another will affect cobalamin level. There is no need to remove oneself from folate at all. Only a trial of active b12s plus certain cofactors can definitively demonstrate b12 deficiencies. All vegetarians are deficient unless they eat enough animal based foods, period.

I mentioned stopping the 1 a day, and No Shot, and I'm staying away from anything that lists folate. But Im afraid there is still folate in the flour, and its not listed as an ingredient. Isnt folate required by law in EVERYTHING? Thanks Jim Hi Jim, You sound obsessed with getting "true results", whatever that means. The results are all true results whatever the numbers unless the lab botches the test. Folate in NO WAY affects serum cobalamin. Nothing but cobalamin affects serum cobalamin. It takes about two weeks of no cobalamin consumption of any kind for the serum test to reflect only the tissue equilibrium level rather than current consumption plus tissue equilibrium level, is that what you are looking for? However, you could take enough folate to fill a boxcare and it won't affect the serum cobalamin level. Folate contains no cobalamin of any kind. uMMA is considered at least as important in detecting b12 deficiencies as Hcy (homocysteine). It detects the other kind of deficiency, that of adenosylb12 which powers the mitochondria. Hcy detects a specific breakdown in the methionine-homocycteine loop and DNA replication. Neither test can say that you do NOT have functional deficiencies. Neither does a serum test. 2/3 of b12 responsive people won't show up positive any any of those 3 tests. No Shot methyl B12, 5000mcg is clearly an inferior product. It can allow you to absorb at best about 50mcg of methylb12. Jarrow sublingual methylb12 5000mcg allowed to linger for 45 minutes can allow you to absorb about 750mcg. Further No Shot contains 800 mcg of folic acid which you say you are avoiding. It also contains lactose. If you are bloating from yogurt chances are you have lactose intolerance. After you have your blood drawn why don't you start on some brands of active b12s and cofactors that will more likely give you very definite results. What are your symptoms? All of them. A common b12 deficiency symptom is "brainfog" where you can't think clearly. Enriched flour and all products made from it do contain small amounts of folic acid. But again that WILL NOT AFFECT SERUM COBALAMIN. How can I make that more clear? Whatever you are reading that is causing you concern, I wish you would quote here so I can see why you are getting confused. No test is fool proof. And no test EXCEPT A TRIAL can definitively show a lack of functional b12 deficiency. No set of tests can show that. It just isn't possible. What purpose do you want to "trust" the test for? Any number you get will be too low to assure no deficiency. A single b12 dose can send it up over 200,000 pg/ml. A steak dinner can send it up 500pg/ml. If you want it to show deficiency, it might. If you want it to show sufficiency, it CAN'T. Any number it gives does not prove that you won't respond to one of the better brands of methylb12 or adenosylb12. Please do yourself a favor and read from the back end of the b12 forum towards the front for a couple of hours. You will become more knowledgable. The information from Sally is largely obsolete and never included information on active b12s in the first place. If you want to heal yourself and be sure that you don't have either kind of b12 deficiency you need to take both active b12s and the correct cofactors. Good luck.

  • Sunwatt,my wife and i both have been vegentarians for a few years now also,but my wife had really been going downhill fast until i stumbled across this forum a few months ago,her doctor told her she wouldnt get any better,and i was sitting right there and couldnt believe it.,its even worse because she has been in a wheelchair for eighteen years now from a car accident.Anyway we made a order from iherb and she is getting better slowly and it will take some time,the doctors were really late on taking test to see why she had been feeling so bad for so long.So if you would like to save five dollars on a order at iherb.com you can simply use this code at the end of your order ,that goes for everyone,you can only use it once,but hey five bucks is a little help.
