Verifiable Science

At low to moderate doses, caffeine has been shown to target the central nervous system (CNS) and act as cognitive support, promoting alertness, vigilance, attention, and reaction time.¹ Research indicates that it promotes the encoding of new information and delays fatigue. In a study of 88 young adults, the ingestion of 200 mg caffeine significantly enhanced problem-solving abilities, although it did not alter working memory or creativity.² It is believed to exert its effects on the CNS via the adenosine receptors, promoting neurotransmitter release and dopamine concentration, motor unit firing rates, and comfort.³ In a study of 15 professional e-gamers, 3 mg/kg body weight caffeine promoted accuracy and decreased reaction time.⁴ Numerous studies on athletes suggest that caffeine promotes endurance and performance output likely through these same mechanisms.⁵ In an incremental exercise-cycling study conducted in recreationally active men, 4 mg/kg body weight caffeine improved time to exhaustion by 12% and significantly decreased perception of effort and subjective fatigue.⁶ L-theanine is a component of green tea that promotes normal brain alpha-wave activity, helping calm the sympathetic nervous system for a relaxing effect without drowsiness. It also has been shown to support positive mood and cognitive function, in part by promoting healthy neurotransmitter function and neuroprotection. In combination studies, l-theanine has been reportedto moderate some of the effects of caffeine on the CNS, promoting vascular relaxation and local cognitive processing.^7,8 Coffeeberry^® is a concentrated whole coffee fruit extract from Coffea arabica containing naturally occurring caffeine and polyphenols. Preliminary research suggests coffee fruit polyphenols support healthy vascular endothelial function and BDNF.^9,10
