Independent research on children's health. No brand deals.

Why children, and only children

Most of the research on nutrition, the gut and the brain is done on adults, and most of what parents read is adult research with the word "kids" added to the headline. Children are not small adults. Their microbiome is still forming, their gut lining is thinner, the doses that work for a grown woman can be meaningless or excessive for a seven-year-old, and the questions a parent asks at 4pm are not the questions an adult asks about himself.

So we read the pediatric studies specifically, we say plainly when a finding comes from adult data or from animals, and we write for the person who has to make the decision at the kitchen table, not for a clinician.

How we review products

Every product review follows the same process, and the criteria are written before the first bottle is opened. We do not accept sponsored placements, pre-release access or brand input on a ranking. If a product appears in a review, we chose it because parents are buying it.

Our review process has three phases. First, we analyze the label against the published research: which ingredients, in which form, at which amounts, and whether that matches what was actually tested in trials. Second, we look at the mechanism: where the product works, how it gets absorbed, and whether it addresses the cause it claims to address. Third, we read what parents report across independent platforms and look for consistent patterns, not isolated stories.

We rate every product on five dimensions: where it works, how it clears, what it carries, the delivery format, and whether it repairs. Each dimension receives a score from 1 to 10, and the average produces the overall rating. The strengths and the limitations are listed side by side, for the winner too.

Editorial standards

We cite primary sources whenever possible. That means linking directly to published research in peer-reviewed journals, clinical trial registries and PubMed, and never citing a manufacturer's claim as evidence. Where a study shows an association, we call it an association. Where the evidence is preliminary, we say so.

Every article is written and reviewed by a developmental pediatrician who is also the parent of a child with ADHD. That is a deliberate choice: the person checking the science is the same person who has lived the mornings.

We update our reviews when new evidence emerges or when a company changes its formulation. Updated pages carry the revision date at the top.

How we are funded

The Science of Kids may earn a commission when you purchase through links on our site. This never influences our ratings or the order of a ranking. Products that score poorly are published with the same kind of links as products that score well, and you never pay more by using our links.

We believe transparency builds trust. Our model is simple: we recommend what we would give our own children, and we earn a small percentage if you decide to try it.

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.
