NCT07289165

Brief Summary

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.

  • Current nicotine use \> 100 mg/day.

  • History of chronic psychiatric conditions (e.g., bipolar, schizophrenia, PTSD, depression, etc.).
  • History of brain disorders \[e.g., stroke, MS, Parkinson's, history of TBI or epilepsy, migraine (\>1 migraine per month), etc.\].
  • Prior gastrointestinal bypass surgery (Lapband), etc.
  • Other known gastrointestinal or metabolic conditions that might impact nutrient absorption or metabolism, e.g., short bowel syndrome, Inflammatory bowel syndrome (IBS), Inflammatory bowel disease (IBD; e.g., Crohn's, ulcerative colitis), diarrheal illnesses, history of colon resection, gastro paresis, Inborn-Errors-of-Metabolism (such as PKU).
  • Chronic inflammatory condition (e.g., rheumatoid arthritis, Lupus, HIV/AIDS, etc.).
  • Previous medical diagnosis of asthma, gout, or fibromyalgia.
