NCT ID NCT06032156
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at whether a single dose of a ketone supplement can improve blood flow to the brain and thinking skills in young adults. Twenty healthy people aged 18-35 took either a low dose, high dose, or a placebo drink. Researchers measured brain blood flow and memory performance over two hours. The goal is to understand if ketone supplements can help the brain work better without needing to fast.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
ketone monoester supplement (R-3-hydroxybutyl R-3-hydroxybutyrate)
What this could lead to
If successful, this could point toward using ketone supplements to boost brain blood flow and mental performance in healthy people.
What could go wrong
This is a very small, early study in healthy young adults, so results may not apply to older or unhealthy populations. The effects on cognition are still uncertain.
