ADHD and Gut Health: What the New Research Actually Shows

Seven studies from the last four years, read one by one. What is measured, what is only an association, what has been tested.

Read the research
Featured

Almost all of a child's serotonin, about 90%, is built in the lining of the gut, not in the brain. It is made by cells that turn one raw material, tryptophan, into the chemical that settles a child: sleep runs on it, appetite runs on it, getting told no without a forty-minute meltdown runs on it.

Study after study now finds that children with ADHD carry measurably less variety of bacteria in their gut than other kids. The most common reason is one nobody blames: antibiotics. What grows back after them is not what you wanted back, and the lining where everything a child eats is absorbed pays the price.

About the Editor

Dr. Tessa Ashcombe, MD, FAAP

Developmental Pediatrician · 11 years in practice

Dr. Ashcombe is a developmental pediatrician who has loved her job for eleven years, and a mother whose own son has ADHD. That is where this site started: with the questions she kept having to answer at home that nobody had answered in the exam room. She reads the studies, follows the mechanisms, and writes down what the evidence actually supports, so parents can tell the products that reach the child from the ones that stay in the bottle.

Full bio

Evidence-First

Every claim links to a peer-reviewed source. Studies are cited, the method is explained, and preliminary evidence is flagged as preliminary.

Same Criteria for Everyone

Products are scored against criteria written before testing. The strengths and the limitations are listed side by side, for the winner too.

Plain-Language Science

Dense clinical literature, translated into something you can read at the kitchen table while dinner is going cold. Without dumbing it down.

The Science of Kids
