Leucovorin and Autism: What the Folinic Acid Research Actually Shows | John Slattery
Biohacking Autism with Nadia Elkhatib.Show Notes
Leucovorin, also known as folinic acid, has become one of the most discussed topics in autism research. John Slattery, co-author of the 2018 randomized double-blind placebo-controlled trial of folinic acid in children with autism and language impairment, joins Nadia Elkhatib to separate the research from the noise. They unpack what the trial actually measured and found; why folate receptor alpha autoantibodies (FRAAs) may matter; how FOLR1, cerebral folate deficiency, the folate receptor, and the reduced folate carrier affect folate transport to the brain; and why testing has to be interpreted in the context of the individual. John also explains the connections among folate metabolism, methylation, redox balance, and mitochondrial biology, along with the uncertainty around responder and non-responder profiles. They clarify the FDA’s 2026 approval of Wellcovorin (leucovorin calcium) for FOLR1-related cerebral folate transport deficiency — and why that is not the same as a broad FDA approval for autism.

My son was nonverbal. I was told he would never speak, and that if a child does not talk by five, he never will. Jimmy started talking at eight. This is the 11-minute version of my episode on autism recovery: the stories you never hear, what recovery means, how Jimmy started talking, and the five things it takes.
Recovery from autism is possible. I’ve seen it, and my own son isn’t there yet. This is my honest answer after 22 years: the families who got there, why you never hear about them, what recovery means, how my son started talking at eight, and the five things it takes.

You get the exact baseline panel from this episode in one email, the episode summaries every week, and, if you tick the box, a place on the wait list for the private community. IN THIS EPISODE The recovery stories you never see on social media, and why Two sons, same house, same protocol, one recovered What recovery means and what it does not (the truck analogy) Where Jimmy is today, 22 years in Why there is no one protocol for recovery How Jimmy started talking at eight: Dr. Klinghardt, Babesia and artemisinin The five things it takes, in order Three things to do this week, not five WHAT YOU WILL HEAR Jimmy is not recovered. We have made real progress, and the work continues at 22. Artemisinin was one herb used under Dr. Dietrich Klinghardt’s care alongside pharmaceuticals, for an infection that had been identified. No doses or sources are given, and this is not a recommendation to buy it. The recovery stories are what parents told me directly and what I saw myself. They are not a study.

Caregiver burnout, chronic stress and brain health: the core conversation in a 34-minute Essentials edition for caregivers who want a focused starting point.
Caregiver burnout deserves more than being dismissed as "just stress." When you've spent years caring for someone else, what questions should you be asking about your own brain health?
This is the Essentials edition, a 25-minute cut of our conversation with Dr. Uli K. Chettipally, MD, MPH, an emergency physician, Silicon Valley entrepreneur, and father of Siri, a non-speaking young woman with autism.
