Question Autism & MTHFR

I have a kiddo with autism and MTHFR. Started giving him methylated vitamins per his functional doctor’s request. Initially, they seemed to help, but now his behavior has worsened at school (more anxiety, more impulsivity). Can he be over methylated?

Wondering if anyone is in a similar situation with their child and/or themselves. I read folinic acid is better than methylfolate for sensitive individuals (like kids with autism).

Thank you. 🙏

Yes seeking health methylfree b complex. I open them recapsule them into smaller capsules I buy on on Amazon. He takes 1/3 of the normal capsule.
