Ketone supplements to protect blood vessels and kidneys from high-salt diets in older adults

Dietary Ketone Supplementation as a Novel Strategy to Attenuate the Adverse Vascular and Renal Consequences of High Dietary Salt in Older Adults

NIH-funded research Trustees of Indiana University · NIH-11159549

What this research studies

You would be invited as an older adult to take an oral ketone supplement (a ketone monoester that raises beta-hydroxybutyrate) while researchers monitor how your blood vessels and kidneys respond to a higher-salt diet. The team will collect blood and urine samples and measure blood pressure and noninvasive vascular and kidney function tests before and after supplementation. This approach builds on animal work suggesting ketones can counteract salt-related harm and uses supplements because they are easier to take than strict ketogenic diets. Study visits will likely occur at the research center and include routine testing and follow-up.

Who could benefit from this research

Good fit: Ideal candidates are older adults who regularly consume a high-salt diet or who are at risk for salt-related high blood pressure or kidney problems.

Not a fit: People with advanced kidney failure, those on dialysis, pregnant people, or anyone advised by their doctor to avoid ketone supplements may not benefit or be eligible.

Why it matters

Potential benefit: If successful, this could provide a simple supplement option to lower salt-related blood pressure and protect kidney and vascular health.

How similar studies have performed: Animal studies have shown benefit from raising beta-hydroxybutyrate and ketone supplements have been used safely in other human tests, but this specific approach in older adults is only now being tested.
