Sports Research L-Theanine 200mg with Suntheanine is a dietary supplement designed for individuals seeking a natural way to manage stress and enhance mental clarity. It caters to busy professionals, students, or anyone facing high-pressure situations, providing a sense of calm without the sedation associated with other relaxants.

This ensures that users receive a consistent and effective dose, which has been shown to increase alpha brain waves, promoting a state of relaxed alertness. This makes it an excellent alternative to caffeine or energy drinks for those who want focus without the jitters.

Formulation: Straight L-Theanine vs. Nootropic Blend
Decide whether you want a pure L-Theanine supplement or one combined with caffeine. The Sports Research L-Theanine 200mg is ideal if you already get caffeine from other sources or prefer a caffeine-free option for evening use. The L-Theanine + Caffeine Nootropic is designed for those who want a synergistic boost for focus and energy without the typical jitters. Both come in liquid softgels for fast absorption.
