Zhou Energy + Focus Caffeine with L-Theanine
by Zhou Nutrition
"The smart caffeine stack — clean energy without the jitters"
Overview
Zhou Energy + Focus combines 100mg of natural caffeine with 200mg of L-theanine per capsule — the most well-studied nootropic stack in existence. The caffeine provides alertness and energy while L-theanine (an amino acid from green tea) promotes calm focus and eliminates the jitters, anxiety, and crash associated with caffeine alone. This 1:2 caffeine-to-theanine ratio is the most researched and recommended ratio for cognitive performance.
