Official title
Bacterial Responses to Enteric Alterations After Ketones
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this observational study is to learn if a ketone ester can improve the content of the gut microbiome. The main questions it aims to answer are: * Does a ketone ester reduce age-related signatures in the gut microbiome? * What changes occur in the gut microbiome after consuming a ketone ester? Participants will: * Take a ketone ester every day for seven (7) days * Collect and ship stool samples within seven (7) days before, during, and within seven (7) days after the study period * Measure their ketone levels with a urine strip every day after having the drink * Answer questions about their typical diet on a normal day * Record their symptoms, if any arise
