The evidence in words
The interaction
L-Theanine and Caffeine — a synergy interaction. The A-grade nootropic pairing.
What to do
These two complement each other — taking them together is reasonable and, for the stated reason, may work better than either alone.
About L-Theanine
L-theanine is an amino acid found almost uniquely in tea. Alone it promotes a relaxed-but-alert state; its best-known use is smoothing caffeine.
The bigger picture
Supplement–drug and supplement–supplement interactions are the reason a stack should be read as a system, not a list. This platform's interactions graph maps them; the medication side always belongs with the person who prescribes it.
