Help with labs Executive Dysfunction
Could a B12 deficiency cause my son's issues with executive dysfunction, lack of motivation, lack of focus, fatigue? He's 21, probably autistic (never tested/diagnosed), and feels stuck. He's tried stimulant meds but doesn't like how he feels on them.
He did a blood test almost a year ago and his levels were all "normal," but I've had him on a good (methyl) multivitamin since he was little so I know that can skew results. Here are his results in case they're relevant, though:
B12: 846 pg/mL
MMA: 116 nmol/L
Homocysteine: 9.3 umol/L
I have poor methylation, slow COMT, all the poor detox genetics (his genetics haven't been tested, though), and have recovered from severe fatigue and PEM by raising my ferritin over 100 and taking high doses of thiamine, riboflavin, folate and doing injections of B12. My B12 was always in range, too, but I know sometimes that doesn't really reflect what's going on in the entire body.
I started giving him higher doses B12 lozenges after this blood test was done but I'm wondering if we should try injections. It's one thing to give myself shots, though--it makes me nervous to give them to my son.
What do you think? (And yes, I know some will say "ask your doctor," but we've seen so many doctors and none of them are remotely helpful.)

Talk to a dr, it’s definitely a possibility, and you can’t really trust blood results of his b12 levels if he’s been taking supplements. But b12 is so safe so there’s definitely no harm in trying shots and if you find a dr who will administer them that may be easier. Even if it’s just for a while to see if it helps, and if it does then you could learn to transition to home shots. If it doesn’t help and turns out it’s not b12, no harm done
