First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a single dose of a ketone salt supplement could improve heart function in 20 people with stable heart failure. Participants took either the ketone supplement or a carbohydrate placebo before a heart MRI. The goal was to see if the supplement could help the heart pump more effectively.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
exogenous ketone salt supplement
What this could lead to
If it works, this could point toward a simple dietary supplement to help improve heart function in people with heart failure.
What could go wrong
This is a very small, early-stage study with only 20 participants. The supplement was taken just once, so any effects may be temporary or not meaningful in the long run.
