There is a section in the course that covers Leucovorin (Folinic acid) as an "off-label" intervention for autism symptoms more specifically speech. However based on observation in treating patients in my own practice I've seen it improve social reciprocity as well. I recently came across a study done in China recently that echos this finding. I wanted to include it here: https://pmc.ncbi.nlm.nih.gov/articles/PMC12073535/ Those who have used Folinic acid or leucovorin with their child have you noticed this as well?
