住在厄瓜多尔和秘鲁ar的上游地区e a group of indigenous people called the Amazonian Kichwa. Regarded as the guardians of the rainforest, the Kichwa have an elite group of warriors known as the"Vigilante Nocturno,"or Night Watchmen. For centuries these specialized hunters would drink a tincture of brewed guayusa leaves to help sharpen their alertness. The Kichwa share stories about how the guayusa would provide enhanced mental focus, stamina, and reaction time yet allow them to sit perfectly still at night. Scientific research may validate these experiences revealing that the active compounds in guayusa may be a timely addition to today's natural energy market thanks to its many nootropic benefits.
What is Guayusa?
瓜尤萨（Guayusa）发音“ gwhy-you-sah，”is a caffeinated holly species that grows only in the upper Amazon basin of Ecuador and Peru. Historical records suggest that leaves from guayusa have been used and traded since at least 500 CE.iTraditionally brewed guayusa leaves are consumed much like tea. However, guayusa is not related tocamellia sinensisused to make green or black tea varieties. Instead, guayusa is a cousin plant to yerba mate and contains an intricate makeup of antioxidants and caffeine (related article:The Story of Guayusa).
Study: Guayusa for Nootropic Performance
Centuries of anecdotal data illustrating the effects of guayusa within the indigenous Kitchwa communities inspired Texas-based ingredient company,Applied Food Sciences(AFS), to see how guayusa would stack up against other more popular forms of caffeine. Over the last eight years, AFS has been studying the active compounds in guayusa to prove the ingredient's safety and efficacy for use in food and nutritional supplement applications.
Applied Food Sciences recently launched its brandedamatea®Maxorganic guayusa extract. Using a patented process to enhance the naturally occurring antioxidants and caffeine from guayusa leaves, AmaTea®Max may help improve cognitive performance by increasing mental focus, stamina, and reaction time with fewer jitters than other forms of caffeine. In addition, AFS achieved a historical first 'no questions letter' from the FDA's Office of Food Additive Safety (OFAS) for a natural caffeine-containing botanical ingredient in response to its GRAS petition.
As a result, the ingredient is attracting a lot of interest from the premium energy market, which caters to sports nutrition, nootropics, and esports products.
Elevating Gaming Performance
At the University of Memphis College of Health Sciences, Dr. Bloomer and his colleagues recently concluded a first-of-its-kind gaming study to determine the effect of AmaTea®Max on mood, cognitive measures, and gaming performance while being mentally fatigued throughout 4 hours of gameplay. The investigators hypothesized that both AmaTea®Max and caffeine would improve outcome measures more than the placebo. This ended up being the case.
No increase in jitters
One of the most substantial outcomes of the Dr. Bloomer study was that active gamers using AmaTea®Max revealed no increase in jitters after one hour of gameplay. Comparatively, gamers using synthetic caffeine noted a statistically significant rise in jittery sensations.iiMost likely, this is a result of AmaTea®Max's unique ability to modulate adrenal hormones commonly induced by caffeine alone. In a separate double-blind crossover study by Dr. Krieger et al. (QPS MRA), subjects were given AmaTea®Max compared to synthetic caffeine. The study revealed that AmaTea®与其他形式的咖啡因相比，MAX刺激了较低量的“战斗或飞行”激素，称为肾上腺素（通常称为肾上腺素）。iii
持久的能量和耐力
更少的抖动并不意味着能量更少。实际上，阿玛蒂亚的咖啡因®MAX具有吸收率和持续能量，可与所有咖啡因的来源竞争。在整个游戏研究中，受试者进行了基线测量，然后在四个小时的时间内玩游戏Fortnite。在此期间，近三分之二的参与者消费amatea®Max reported an increase in vigor (defined as sensations of energy, effort, and enthusiasm) after one hour of gameplay. Despite the rigors of the test, similar to caffeine, AmaTea®Max受试者还报告了精神疲劳的减少，尤其是经过两个小时的游戏玩法，安慰剂。ii
Enhanced Focus, Reaction Time, and Gaming Performance
Determining the effect of AmaTea®最大的认知措施和游戏性能需要在4小时的游戏玩法中进行多次测试。当考虑获得结果度量所需的额外时间时，总测试时间约为六个小时。除了游戏中捕获的数据外，该研究还进行了血压，心率，数字符号替代测试，布鲁内尔情绪量表，主观感觉，反应时间（GO/no-go）和心理表现测试的测试（AX-cpt）。
The AX-CPT, or AX-Continuous Performance Test, is a cognitive test that includes a series of cues and probe sequences.ivPrior to gameplay, subjects underwent the AX-CPT for 30 minutes. This helped to ensure the subjects reached mental fatigue within the 4 hours of gameplay. Subjects again took the AX-CPT for 30 minutes after gaming. The results showed that more than half of the participants using AmaTea®Max保留了更多的焦点，并改善其AX-CPT分数。尽管没有统计学意义，但值得注意的是Amatea®Max subjects were the only group to see an increase in performance on the AX-CPT after the 4 hours of gameplay.ii
Reaction time is an important performance indicator for gaming performance. Beyond the analysis within the game itself, the study utilized a go/no-go task to capture data more accurately. Impressively, around two-thirds of AmaTea®Max subjects showed improvement in reaction time after one hour of gameplay. After four hours of gameplay, the study revealed a consistent pattern as 65% percent of participants improved reaction time after taking AmaTea®Max.ii
In gaming, however, it is all about winning. After all, a nootropic energy ingredient that aids in focus, stamina, and reaction time, all with zero changes in jitters, should result in better gaming performance, right? Well, the numbers don't lie. On the condition effect for kills per match in
Fortnite，将近四分之一的活跃游戏玩家使用Amatea®Max increased their kills relative to placebo, with over twelve percent higher kills for AmaTea®与咖啡因相比最大。ii
结论
最后，希望使用饮食补充剂进行游戏性能的活跃游戏玩家可能会受益于Amatea®在游戏之前的最大程度要比安慰剂比安慰剂更大的活力和更低的疲劳，而仅比咖啡因更少。不同的游戏刺激，游戏玩法的不同时间或补充剂的不同剂量可能会产生不同的结果。
以更多的重点和更少的烦恼来激发游戏性能。amatea®Max is caffeine with antioxidants, a perfect combo for work, sports, and gaming. This ingredient is ideal for supplements, food, and premium energy drink that want to get the most out of naturally derived energy, unlike any other caffeine. In addition, the guayusa for AmaTea®Max is sustainably grown in the Amazon, supporting thousands of indigenous farming families.
