What is ADHD?

ADHD, characterized by inattention, hyperactivity, and impulsivity, disrupts normal life patterns. L-Theanine acts by modulating neurotransmitters, such as dopamine and serotonin, promoting a sense of calm and focus amidst these challenges.

Autism is a complex neurological and developmental disorder that can manifest in a variety of ways in adults. Here, you can find some signs of mild autism in adults.

How L-Theanine Works in the Brain
