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

Will I undergo more tests?

Perhaps: you are iron deficient either due to inadequate iron intake or poor absorption. You need additional iron in your diet through food sources and supplements. Add citrus to every meal containing iron to help with absorption. If you are not responding to supplemental iron you may be tested for sources of blood loss and/or inflammation affecting absorption. Consider gluten sensitivity. ...Read more

Masks anemia only: High folate (folic acid) can mask megaloblastic anemia caused by B12 deficiency but does not affect B12 levels. The high B12 levels you have are proof that you don't have B12 deficiency. I don't know what ida is. Hair loss ; sob can have many causes.

Can taking vitamin d tablets affect B12 blood results?

No: A high B12 means nothing. If you have a low B12, you need to asking, "Why is it low?" and "What do I do to correct the situation before I end up with permanent brain damage?" If you're a non-supplementing vegetarian, please re-examine your choices. If there is any possibility you have pernicious anemia or another absorption problem, get worked up and treated. ...Read more

How do you FEEL?: I'm glad this was recognized in time. You'll need a transfusion only if you're seriously symptomatic and can't last long enough to have your stores rebuilt by supplements. Please comply. Your best source of iron is red meat. Iron in spinach is bound to an acid that makes it not absorbable and broccoli as a wonderful source of iron is a myth made up by vegetarians.

My vitamin B12 blood test result is 1114 pg/ml is this bad?

Vitamin B12 level: Can be high for several reasons: 1) you are taking vitamin B12 as a supplement or eating a diet high in b12. 2) your body cannot metabolize B12 so it stays in your blood stream but does not get into your cells where it needs to go for it to work. There are tests to determine if the latter is the case. Treatment would be geared towards getting the B12 to be utilized by the body appropriately. ...Read more

The other possibility is that you are B12 def., but take folic acid supplement. Folic acid will correct the anemia of B12 deficiency but—AND THIS IS IMPORTANT—not prevent ongoing neurological damage due to B12 deficiency.

Your body doesn't: make vitamin B12 so you need to get it from animal-based foods or supplements. It is something vegans/vegetarians need to be especially mindful of. Conditions which impair absorption also contribute: atrophic gastritis (thinned stomach lining), lack of intrinsic factor (pernicious anemia), GI surgery, small intestinal disease, heavy drinking,etc. Most often, supplements needed lifelong.

Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually.
