Caffeine + L-theanine: the focus pairing, explained
Caffeine alone is a blunt instrument — it lifts alertness but can bring jitters and an afternoon crash. Pairing it with L-theanine, an amino acid from green tea, is one of the best-studied combinations for calm, focused attention.
How they balance
Caffeine raises alertness; L-theanine promotes a relaxed, focused state and takes the edge off. Together they support attention that feels steady rather than wired.
The dose that matters
A common, well-tolerated pairing is around 100 mg caffeine with 200 mg L-theanine (a 1:2 ratio). Our Focus formula uses exactly that, plus citicoline for mental clarity.
As with anything containing caffeine, mind your total daily intake and avoid it late in the day.
