For me L-methylfolate has helped with ... everything quite a bit since discovering I have an MHTFR mutation. Lots of more mental and physical energy with no side effects.

I used to consider typical vitamins as not-necessary if you eat reasonably well -- but I've reconsidered that position and supplement B12 and others as well.

ADHD meds were a mixed bag - they improve focus and attention, but at the cost of physical discomfort, insomnia, anxiety, etc. Overall not helpful really.
