What this research studies

You would take a ketone ester supplement that raises levels of beta-hydroxybutyrate, a natural molecule linked to fasting and energy use. Researchers at multiple sites will enroll older adults with frailty and measure changes in physical performance, energy, inflammation, immune markers, and other aging-related biomarkers. The team combines experts in geriatrics, ketone biology, and immunology to connect biological effects to everyday function. This is a proof-of-concept effort to find out whether a pill-like ketone approach could help reverse aspects of frailty.

Who could benefit from this research

Good fit: Ideal candidates are older adults who meet clinical criteria for frailty and can attend visits at participating study centers.

Not a fit: People who are not frail, substantially younger, or who have medical conditions that make ketone supplements unsafe are unlikely to benefit from this trial.

Why it matters

Potential benefit: If successful, the approach could improve strength, energy, and day-to-day independence for people living with frailty.

How similar studies have performed: Earlier human studies show ketone esters change metabolism and inflammation, but using them specifically to treat frailty is a novel and early-stage application.
