Malabsorption of B 12
(Escanaba, MI, USA)
My son, 8 years old, had a blood test drawn about a year ago which showed his B 12 level to be 1300+, but yet he has many symptoms of low B 12 including, but not limited to, tingling of his hands and feet, Vitiligo, and very poor memory(especially names??).
I was once told, shortly after this blood test, that maybe his body wasn't absorbing B 12. At first I thought, that's impossible. How do I find out whether he's getting the benefit of B 12? Urine test? Thank you in advance!
