The purpose of this study is to examine how the body absorbs, digests, and metabolizes three different investigational ketone dietary supplements (ketone monoester, ketone tri-ester, ketone salt) and to assess gastrointestinal tolerance or other adverse effects. This study is considered investigational because data are being collected on the differences over time between three active study products. Consumption of these study products are not intended to diagnose, treat, cure, or prevent any disease.
