Look at reference: In the US, the reference range for it B12 for this age is 250-1205 pg/ml. Therefore, if I were to advise on this matter, I would say his level is normal. There are no particular reasons for concerns in mildly elevated levels. Most of the clinical problems arise from inability to absorb this vitamin from the GI tract or in certain extreme diets such a vegan diets without supplementation with B12

That's fine: An isolated high B12 never means anything. Reference ranges are set so that a few percent of healthies fall outside on either end. Junior has a slightly increased amount of B12 carrying protein. Relax and be glad he's healthy.

My vitamin B12 went from 178 to 758 on my next blood test 2 years later. Would a daily supplement really raise it that much? I am a 50 yr old woman.
