I think this is based on poor understanding of genetics. A lot of neurodivergent people have mutations in a gene (MTHFR) that deals with processing folate, but that doesn't mean they have reduced folate by itself. But, taking folic acid if you have decreased ability to process it can actually cause health problems. I'm not sure what the difference is for folinic acid, but this just all sounds very pharma-bro and unscientific to me
