About this study

This study is being conducted to evaluate how different formulations of the Feel Free® Tonic containing Kava, Kratom, or a combination of both are processed in the body in healthy adults. The goal is to compare the pharmacokinetic profiles and safety of the combined herbal formulation with Kava alone and Kratom alone to better understand how these ingredients behave when taken individually versus together.
