CaffPhenol 60ct

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.
