High Salt Intake for High Blood Pressure
(KEAS-O Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores whether ketone supplements (KEAS) can protect against the negative effects of excessive salt intake, such as high blood pressure and kidney problems. Researchers aim to determine if these supplements improve heart and kidney health by reducing inflammation and enhancing blood flow. Participants will undergo different phases, including taking a placebo (a harmless pill with no active ingredient) and consuming salt with or without ketones, to observe bodily reactions. Individuals aged 60 to 85 with controlled blood pressure (not exceeding 150/90) and no major health issues like diabetes or heart disease may be suitable for this trial. As an unphased trial, this study offers a unique opportunity to contribute to groundbreaking research that could lead to better solutions for heart and kidney health.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. However, if you are on blood thinners or have conditions that prevent safe exercise, you may not be eligible to participate.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that ketone supplements are generally safe for people. Studies have found that ketone salts, a type of supplement, can lower blood pressure in adults over a few weeks. Another study found that these supplements do not cause serious side effects in healthy individuals. They increase blood ketone levels without major problems. However, in some cases, a slight increase in blood pressure occurred after taking ketone supplements. Overall, these supplements are usually well-tolerated.12345
Why are researchers excited about this trial?
Researchers are excited about the trial of KEAS for high blood pressure because it introduces a new approach by combining dietary salt intake with ketones, which isn't common in standard treatments like ACE inhibitors, beta-blockers, or diuretics. Unlike typical medications that target different pathways to lower blood pressure, KEAS leverages nutritional interventions to potentially influence blood pressure and overall cardiovascular health. This unique combination might offer additional benefits by affecting inflammation and immune responses, which could lead to a more holistic approach to managing high blood pressure.
What evidence suggests that ketone supplementation could be effective for high blood pressure?
Research has shown that ketone supplements might help with high blood pressure, particularly when linked to high salt intake. In rodent studies, these supplements prevented blood pressure increases and protected blood vessels and kidneys from salt-related damage. Some human studies found that ketone salts can lower systolic blood pressure in healthy individuals. Evidence also suggests that a ketone compound called β-OHB might lower blood pressure by improving blood vessel function and supporting the heart. However, some studies indicate that ketone supplements might not significantly affect blood pressure. This trial will further explore these effects by testing different combinations of salt and ketone supplements across various treatment arms. While early results are promising, more research is needed to confirm these effects in humans.12678
Are You a Good Fit for This Trial?
This trial is for older adults who may be experiencing high blood pressure and are at risk of developing complications like kidney disease or cardiovascular issues due to high salt intake. Participants should not have any conditions that would exclude them from the study.Inclusion Criteria

Trial Overview
The study tests if ketone supplements can prevent negative effects of a high-salt diet in older adults, such as increased blood pressure, poor blood vessel function, and kidney damage. It involves comparing different combinations of salt and β-OHB (a type of ketone) intake.
How Is the Trial Designed?
Participants will consume each of the supplemental interventions for 10 days (in this assigned order). On Day 10 of each interventional condition, participants will arrive at the laboratory where the investigators will assess resting blood pressure, arterial stiffness, endothelial function, renal blood flow, and submaximal exercise blood pressure reactivity. Blood will be collected to investigate inflammatory and immune responses to the dietary conditions. After a washout period, participants will consume the next assigned supplemental intervention for 10 days, and repeat the Day 10 assessments. After another washout period, participants will consume the final assigned supplemental intervention for 10 days, and again repeat the Day 10 assessments.
