125 peer-reviewed studies

What the evidence says

Mostly mechanism / observational

Most Exogenous Ketones studies are mechanism or observational rather than RCTs that measure a clinical effect — keep findings provisional.

Most evidence is from high-quality meta-analyses and randomised trials published 1994–2026 with a typical study size of 16 participants.
