When people take ketone supplements, their bodies produce more aldosterone—a hormone that helps regulate salt and water balance—and release more of a kidney protein linked to sodium handling, likely as a reaction to increased salt loss in urine, even though overall blood pressure doesn't change.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether ketone monoester consistently induces aldosterone elevation across populations and whether this response correlates with sodium excretion patterns or clinical outcomes.
A systematic review and meta-analysis of all RCTs measuring plasma aldosterone, renin, and urinary ENaCγ in response to ketone monoester supplementation, stratified by dose, duration, and baseline health status, with pooled effect sizes and heterogeneity analysis.
Whether repeated ketone monoester dosing leads to sustained aldosterone elevation or adaptation over weeks, and whether this affects sodium retention or blood pressure regulation.
A double-blind RCT with 80 healthy adults randomized to ketone monoester (300 mg/kg thrice daily) or placebo for 8 weeks, measuring plasma aldosterone, renin, ENaCγ excretion, and 24-hour sodium balance weekly, with a washout period and crossover design.
Whether individuals with higher aldosterone responses to ketone supplements are more likely to develop sodium retention or hypertension over time.
A prospective cohort study of 1,000 healthy adults measuring aldosterone response to a single ketone monoester dose and following them for 5 years to assess incidence of hypertension, eGFR decline, or fluid retention events.
Whether individuals who develop salt-sensitive hypertension after prolonged ketone use show higher baseline aldosterone responses compared to non-responders.
A case-control study comparing 50 individuals who developed hypertension after 6+ months of ketone monoester use with 100 matched controls, measuring their aldosterone and ENaCγ response to a standardized ketone challenge.
Whether current ketone monoester users have higher average aldosterone levels than non-users at a single time point.
A cross-sectional study measuring plasma aldosterone and urinary ENaCγ in 500 healthy adults, comparing 250 regular ketone monoester users (≥3 months, ≥3 doses/week) with 250 non-users, adjusting for age, sex, BMI, and sodium intake.
