High Levels Of Vitamin B12 Symptoms
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 moreSee 1 more doctor answer
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

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
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
