Brief summary
This study is a randomized, placebo-controlled, double-blind, within-subject crossover trial of 25 men and women. The objective of this study is to assess the effects of Dynamine (methylliberine) supplementation on overall well-being including energy, sustained energy, mental stamina, focus, concentration, motivation to accomplish difficult tasks, drive, vigor, positive outlook, maintaining a healthy mood, feelings of well-being, and resilience to stress.
Detailed description
This study is a randomized, placebo-controlled, double-blind, within-subject crossover trial of 25 men and women. Dynamine (methylliberine) is a caffeine metabolite and purine alkaloid found in the kucha tea leaf. Dynamine has become a popular dietary supplement with consumers due to its neuro-energetic effects. Previous research has shown Dynamine can improve energy, mood and focus without the cardiovascular effects of elevating heart rate or blood pressure. In this study, participants will attend 5 study visits. During Visit 1, participants will be screened for participation (i.e., medical history, routine blood work, background baseline diet). During Visits 2 and 4, participants will complete baseline testing including subjective questionnaires that assess energy, sustained energy, mental stamina, focus, concentration, motivation to accomplish difficult tasks, drive, vigor, positive outlook, maintaining a healthy mood, feelings of well-being, resilience to stress in addition to completion of a series of an objective neuropsychological test (Stroop test) to assess mental processing, cognitive flexibility, and attention. After three-4- days of supplementation, participants will return for Visit 3 and 5 where they will take a 4th dose of Dynamine or placebo and repeat the testing outlined at previous baseline visits.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Cognitive flexibility | Change from baseline to 60 minutes, 120 minutes, and 180 minutes post-baseline. | Cognitive flexibility as measured by the Trail Making Test. |
| Well-being | Change from baseline to 60 minutes, 120 minutes, and 180 minutes post-baseline. | Well-being as measured by a 10 cm visual analogue scale, where higher values represent improved feelings of well-being. |
| Cognitive function | Change from baseline to 60 minutes, 120 minutes, and 180 minutes post-baseline. | Cognitive function as measured by the Stroop Test. |
| Concentration | Change from baseline to 60 minutes, 120 minutes, and 180 minutes post-baseline. | Concentration as measured by a 10 cm visual analogue scale, where higher values represent better concentration. |
| Motivation | Change from baseline to 60 minutes, 120 minutes, and 180 minutes post-baseline. | Motivation as measured by a 10 cm visual analogue scale, where higher values represent greater motivation. |
| Mood | Change from baseline to 60 minutes, 120 minutes, and 180 minutes post-baseline. | Mood as measured by a 10 cm visual analogue scale, where higher values represent better mood. |
| Energy | Change from baseline to 60 minutes, 120 minutes, and 180 minutes post-baseline. | Energy as measured by a 10 cm visual analogue scale, where higher values represent increased energy. |
| Sustained Energy | Change from baseline to 60 minutes, 120 minutes, and 180 minutes post-baseline. | Sustained energy as measured by a 10 cm visual analogue scale, where higher values represent increased sustained energy. |
