Outcomes

Primary Outcome Measures

VAS-F (Visual Analogue Scale to Evaluate Fatigue Severity)
Assessment of the mean change in the results of the VAS-F survey from baseline. This consists of 18 items relating to the subjective experience of fatigue with a Fatigue subscale and Energy subscale. The scores can range from 0-10 and the lower the score indicates a better outcome.

Secondary Outcome Measures

BCAT-SF (Brief Cognitive Health Assessment Short Form)
Assessment of the mean change in the results of the Brief Cognitive Assessment Tool (BCAT-SF) survey from baseline. It is a 6-item instrument with a score range of 0-21. The higher the score indicates a better outcome.

5. Study Description

Brief Summary
The purpose of this study is to assess the effectiveness and safety of the Alpinia galanga formulation, Theacrine formulation, and Caffeine formulation on fatigue, mental acuity, and cognitive health among overall healthy participants
Detailed Description
This is a 4-arm pilot, double-blind, randomized, placebo-controlled, parallel design study. A total of 80 subjects (20 per treatment arm) will be enrolled in a randomly assigned sequence to receive either the Alpinia galanga formulation, Theacrine formulation, Caffeine formulation, or placebo in individuals and admit to experiencing occasional fatigue (tiredness) and would like more energy. Participants will need to complete assessments and questionnaires. The primary objective is the evaluation of the change in the response to the VAS-F (Visual Analogue Scale to Evaluate Fatigue Severity) relative to baseline. The secondary objective is the evaluation of the change in the responses to the BCAT-SF (Brief Cognitive Health Assessment Short Form), LSEQ (Leeds Sleep Evaluation Questionnaires), and SF-36 Health Survey (Short Form 36) compared to baseline. Safety and tolerability will be evaluated through the receipt of documentation and responses from the telephone contacts/ emails per protocol.
