“Therefore, consuming stimulating substances like caffeine can have similar effects on those with ADHD. Modest amounts of caffeine have been shown to help improve focus, stimulate the mind, and clear brain fog. Individuals with ADHD benefit from this form of a ‘brain boost’ as it helps them to focus on completing each task at hand.” 

It’s no surprise that many people with ADHD self-medicate with caffeine—sometimes even before they receive a formal diagnosis. However, caffeine usage can come with a plethora of side effects (e.g., heart palpitations, jitteriness, anxious thoughts). That’s where L-theanine comes in.

L-theanine has been shown to mellow out some of caffeine’s stimulant effects and increase alpha waves11 in the brain, which can help you achieve a “flow state” as you work. In a small 2020 randomized controlled trial (RCT) published in Scientific Reports, researchers found that the combination of caffeine and L-theanine was more effective at alleviating ADHD symptoms in boys (including mind wandering, rash behavior, and inhibitory control) than either phytonutrient on its own. 

The zen, focused calm that comes from this synergistic duo can be helpful for individuals with ADHD when they’re trying to channel their energy into a task that requires concentration.
