The L-Theanine + Caffeine Stack
Cognitive Enhancement · Beginner · 30 seconds to take, effects last 3-5 hours
What is The L-Theanine + Caffeine Stack?
The most recommended nootropic stack on r/nootropics by far. L-Theanine (an amino acid from green tea) combined with caffeine produces clean, jitter-free focus without the anxiety or crash of caffeine alone. A double-blind study found it improves accuracy and reduces distraction during demanding cognitive tasks. The 2:1 ratio (L-Theanine:Caffeine) is the community consensus.
