ADHD is often viewed through the lens of neurotransmitters, such as dopamine and norepinephrine—and for good reason. These chemical messengers help regulate attention, motivation, executive function, and impulse control. Magnesium supports more than 300 biochemical reactions and contributes to many processes involved in brain and nervous system function.

Magnesium insufficiency may occur for many reasons, including inadequate dietary intake, chronic stress, medication effects, gastrointestinal dysfunction, or increased physiological demand. Because magnesium supports multiple pathways related to brain and body function, researchers continue to explore its role in broader approaches to optimizing cognitive health.

Theanine, a naturally occurring amino acid found in tea leaves, has been studied for its effects on attention, cognitive performance, stress, and sleep. Research shows that it, when combined with caffeine, may improve symptoms associated with ADHD.
