How It Works
PART 1: THE TACTICS
Together, caffeine & L-Theanine enhance performance in terms of attention switching (selective attention), the ability to ignore distraction, and short-term memory retention.1
PART 2: THE STRATEGY
Korean Ginseng has a stimulatory effect which is not jolting the way caffeine is. It’s more of a subtle but long-lasting energy boost which can last for most of the day, and which has been shown to improve aspects of peoples' working memory performance and subjective ratings of calmness.2 Studies have also showed that it helps improve cognitive performance during sustained mental activity3 & mentally demanding tasks.4
