About this trial
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.

Other outcomes
Modified Drug Effects Questionnaire (DEQ)
To assess the effect of TP on subjective drug effects compared to comparator. This non-validated questionnaire consists of 4 questions scored from 0 to 100, that assesses the participants subjective experience after consuming the TP.
Overall Well Being, Health, and Pain
To assess the effect of TP on overall well-being, health, and pain compared to comparator. This non-validated questionnaire consists of 4 questions scored from 0 to 100, that assesses overall quality of life with questions specifically on physical health and pain. Higher scores indicate better overall well-being, health, and pain.
Ecological Momentary Assessment (EMA) Survey
To assess the effect of TP on mood compared to comparator. A non-validated questionnaire consisting of 13 questions assessing the participants emotional and mental/physical states they are feeling "right now." This questionnaire uses bipolar visual analogue scales in which participants how they feel "right now" on lines between two opposite feelings or physical sensations.
Study Product Perception & Attitude Survey
To assess the effect of TP on study product perceptions and attitudes compared to comparator. A non-validated questionnaire consisting of multiple items assessing participants' subjective experiences with the study product, including effects on daily functioning, energy, sleep, mood, mild stress/anxiety, focus, mild pain, muscle recovery, tolerability, and product quality. Items are scored on a 5#point Likert scale ranging from "Strongly Disagree" to "Strongly Agree." Higher scores indicate more favorable perceptions of the study product (except for the side effects item, where higher scores indicate greater perceived side effects).
