About this study

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
