Why Would I Have High B12 Levels In My Blood
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
High intake: Since vitamins, by definition, are substances that we cannot make ourselves, a high level can only come from high intake. Vitamin B12 is not very toxic, but in high amounts can cause diarrhea, edema and increase risk of clots. If you are taking a vitamin B12 supplement, or injections you may want to cut back (discuss with your doctor if you are taking under a doctor's supervision). ...Read more
If my kidneys and liver are ok and my blood is 46.Why i would have a very high level of B12 in my blood.Is it because i took difen B12 from 8 months?
No: Chronic myelogeneous leukemia, promyelocytic leukemia, polycythemia vera and also the hypereosinophilic syndrome can result in elevated levels of B12 mostly from increased production of haptocorrin. In addition, because the liver stores b12, liver diseases such as acute hepatitis, cirrhosis, hepatocellular carcinoma and metastatic liver disease can also cause a rise in serum b12. ...Read more

Last blood test indicates high B12 level of 1957 .The range is 211-911. Have taken B12 supplemental for years is this harmful to Liver & kidney?
If B12 levels are high >1999, and red & white blood levels are normal, should I be concerned about Leukemia? B12 supplements were stopped 3 weeks ago.
No: There's a fairly common form of leukemia in which B12 tends to go up. If your CBC is normal, you can be as confident that you do not have this particular form of leukemia as you can be confident you are not pregnant. Relax, friend. Everybody has a few labs out of range. You'll simply make your life harder than it already is if you let this stuff bother you. Be glad for good health. ...Read more
