Q: what can cause vitamin b12 malabsorption? especially if you have low value, <109 pmol/l?

Intestine issue: B12 is absorbed in the far end of the small intestine. Conditions that involve that area can reduce absorption (infection/surgery/etc,). Dietary habits that reduce intake (vegan only) can lead to low levels.

Q: my vitamin b12 is 335 pg/ml then it says low: <146 pg/ml i rarely eat cause i dont have a appetite and at times go up to 4 or 5 days w/o food why?

Anorexia: Appetite is a complex process mediated by the brain, emotions, metabolic needs, health of the gut &amp; surrounding organs. Lack of weight loss would be good news here. I recommend a visit to your doctor to discuss the circumstances that preceded your anorexia &amp; that may contribute to its persistence. Simple testing is appropriate. Of note, your B12 level is normal.

Q: does vitamin b12 cause nausea?

: No. Vitamin B12 per se does not cause nausea. If you are taking it in a pill, other ingredients in the pill could be responsible. If you were prescribed B12, talk to your doctor to ascertain if you need to take B12 injections. Wish you good health!

Question 5

what causes high vitamin b12 levels?

Accepted Answer

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.
