A blood test showed that I'm B12 deficient. Serum B12 level of 186 pg/ml, should I take vitamin B12 supplements?

B12: This low will likely cause dementia, spinal cord degeneration and peripheral neuropathy. Keep your level above 550 for the rest of your life. Recovery takes about a year in a young person. I suggest you take liquid sublingual weekly for 3 months then bi weekly thereafter. Its important to check a level after you cut back to twice a month. Use 1 1/2 dropper and hold it under the tongue for 30 sec. ...Read more

I have been having internal tremors in full body since one month. My thyroid level was within range but vitamin d level was 17 and vitamin b12 was 275?

I have been having internal tremors in full body since one month. My thyroid level was within range but vitamin d level was 17 and vitamin b12 was 275?

Internal tremors?: So you feel shaky inside? In other words, no one can see these tremors? If so, this may be due to anxiety & stress. Low vitamin D is unlikely to be cause but should be supplemented for bone health. Likewise w/lowish vitamin B12 for nerve health. This assumes usual reference range. Of note, you/we should really ask for lab's normal reference range that should have accompanied results for interpreta ...Read more

GI problem?: Based on the low levels of several vitamins, I would be concerned about some form of malabsorption syndrome. Do you have chronic diarrhea? Pernicious anemia from low B12? Osteomalacia from low Vit D? You probably need to take some levothyroxine (but will you absorb this?). Sounds like your doctor is giving you vitamins, which is good, but what is the cause of all this? ...Read more

Need 2nd opinion Dr.: You have enough things going on that you need to be working with, or getting a 2nd opinion from an integrative medicine doctor (or ayurvedic physician. Vitamin D absorption is much less in obesity, b/c it gets sequestered (stored and not active) in fat &you need Vitamin B12 to be higher. Your TSH value is very high, so this needs to be managed better too as UR thyroid controls UR metabolism. Impt! ...Read more

I very been prescribed Vitamin B12 shots for neck disk is this common procedure?

I very been prescribed Vitamin B12 shots for neck disk is this common procedure?

B12: No. If you have a normal diet, are not alcoholic, malnourished or have severe chronic disease, it is VERY unlikely you have low B12 levels. This 'shot' is often a GP office money maker. You can always get a B12 blood level drawn, but I probably wouldn't. It also has nothing to do with "neck disk" problems. ...Read more

Had swollen neck glands. Have full pressure feeling in base of neck front. I'm 43 vitamin b12 Def. Sometimes there is a popping feeling when I swollen.

Had swollen neck glands. Have full pressure feeling in base of neck front. I'm 43 vitamin b12 Def. Sometimes there is a popping feeling when I swollen.

Need evaluation: Without an examination by a health professional, we can't be sure what is swollen in your neck: glands underneath the jaw, lymph nodes, thyroid, ? . Certainly feeling pressure "in base of neck front' suggests the thyroid. How the "popping feeling" factors in when you swallow also needs evaluation. See your primary care doctor or an ENT specialist. Good wishes:) ...Read more

What causes high vitamin B12 levels?

Intake + Absorption: Vitamin b12, aka cyanocobalamin, is common in a huge variety of foods; low intake rare. However, none of us absorb B12 directly. Instead, the cells of the upper ⅔ of the stomach which secrete hydrochloric, hcl, acid also produce & secrete a protein, called intrinsic-factor, which binds b12. The small intestines absorb intrinsic-factor with whatever B12 is bound, & the B12 is thereby also absorbed. ...Read more

Could a high level of vitamin B12 affect the digestive system in the body?

Could a high level of vitamin B12 affect the digestive system in the body?

The other way around: Vitamin B12 is not known to be toxic in any amount. However, one of the causes of high blood levels of B12 is liver disease including hepatitis ; cirrhosis. Liver disease certainly affects the digestive system. But it is not high B12 that causes liver disease but liver disease that can cause high B12 levels. As I mentioned earlier, other causes of high B12 include kidney disease ; blood disorders. ...Read more

Hi is there any possible link between vitamin B12 and a bit high estrogen levels?

Hi is there any possible link between vitamin B12 and a bit high estrogen levels?

Nothing definitive: A few studies have been done which show influence in both directions: post-menopausal women who took vitamin B12 (and other) supplements showed increased estradiol levels. Women with surgical removal of uterus/ovaries were given estradiol and showed increased B12 levels! The exact connection is unclear. Eat a balanced diet including meat/dairy products; vegetarians may need B12 supplements. ...Read more

How does one go about lowering a high level of vitamin B12 of 1000? It has been that high since 2010. My B6 is also high - 33.4.

Comments: Am not personally troubled when my patients' B-12 comes back elevated, as it is truly unlikely that there will be any problem in near or distant future, but do have them stop the vitamin and recheck in 3 months. Although B-6 can be toxic in some patients, this too will drop over time if you stop it. Your level is not profoundly elevated, currently. ...Read more

Is it possible to have a vitamin B12 deficiency if your serum level is 250 p/mol? Have every symptom plus high MCV and mch

Is it possible to have a vitamin B12 deficiency if your serum level is 250 p/mol? Have every symptom plus high MCV and mch

As a matter of fact yes: I cannot go into the complex details, but I had two young patient's years ago, both of whom had elevated blood levels of vitamin B12. But both of them also had evidence of thiamin deficiency that would result in deficiency of energy. I concluded that vitamin B12 was collecting in the blood and not being used in metabolism. Try a supplement of thiamin and see whether the vitamin B12 levels come down. ...Read more

I have a high level of Vitamin B12 (2000). I wonder if taking METANX CAPSULE PANAM could be causing my problem? Also I did have a gastric bypass in

Probably: Metanx does, in fact, contain B12 vitamin supplement. It also contains the active form of folic acid, known as methyl folate. Gastric bypass patients usually do not absorb vitamins from their food as well and many physicians will use supplements to make sure patients get the nutrients they need to promote health and well being. ...Read more
