How Dopadrate Supports Your Brain, Body, and Performance
At Dopadrate™, we believe in science-backed supplementation. Below are peer-reviewed studies and clinical references that support the benefits of L-Tyrosine and L-Theanine—especially when paired with caffeine—to support dopamine production, mental clarity, and stress resilience
L-Tyrosine For Dopamine Support
Dopadrate includes L‑Tyrosine, an amino acid that serves as a precursor to dopamine and norepinephrine. These neurotransmitters are associated with motivation, focus, and resilience under stress. The studies below highlight its potential cognitive benefits, especially in demanding situations.
Cognitive Performance Under Stress
A systematic review found that L‑Tyrosine supplementation may help support working memory, attention, and cognitive flexibility during stressful or cognitively demanding tasks.

Sustained Vigilance During Sleep Deprivation
Participants given L‑Tyrosine during 24 hours of wakefulness maintained alertness and reaction time longer than those given placebo, suggesting it may help preserve performance during extended stress.

Maintained Working Memory in Cold Stress
In a controlled study, participants exposed to severe cold (~10 °C) experienced declines in cognitive performance. Supplementation with L‑Tyrosine significantly improved working memory and reaction time, restoring performance to normal levels.
L-Theanine For Focus and Stress Relief
L‑Theanine is known for promoting calm without drowsiness. It’s commonly used to balance caffeine and support clear, focused thinking. Here’s what the research says:
Stress Reduction and Executive Function
A randomized, placebo-controlled trial showed that L‑Theanine supplementation may help reduce stress while improving executive function, sleep quality, and verbal fluency.

Improved Reaction Time and Attention
A single dose of L‑Theanine was shown to improve reaction time and attention in middle-aged adults performing cognitive tests.

Caffeine Synergy: L-Tyrosine and L-Theanine for Smarter Energy
Dopadrate is formulated to complement—not compete with—your caffeine. Below are peer-reviewed studies that explore the potential benefits of L‑Tyrosine, L‑Theanine, and Caffeine when used together to support focus and performance.
Study: Supplementation and Performance in Athletes
A randomized, double-blind trial tested a combination of caffeine, L‑theanine, and L‑tyrosine in collegiate athletes. The study reported improvements in movement accuracy and cognitive tasks under physical stress.

Caffeine and L‑Theanine for Mental Clarity
Research has shown that combining caffeine with L‑theanine may support alertness, task-switching, and working memory, while reducing jittery side effects.
