Why FAMUS Pairs L-Theanine With Caffeine

Energy & Ingredients February 3, 2026 · 1 min read · FAMUS Editorial Team
The quick answer

L-theanine is an amino acid found in tea. FAMUS includes it alongside 125mg of caffeine from coffee berry and yerba maté as part of its four-ingredient functional blend. The ingredient list describes the formula; it does not guarantee a particular effect.

Tea leaves contain both caffeine and L-theanine. That pairing inspired part of the FAMUS ingredient blend, though a finished energy drink is its own recipe.

The four-part blend

FAMUS combines coffee berry and yerba maté as natural caffeine sources with L-theanine and elevATP®. Each bottle has 125mg of caffeine. We chose those ingredients as part of a considered formula beneath the flavor, without promising that everyone will experience the drink the same way.

Flavor still comes first

Havana Nights leads with yuzu, lime and a refreshing mint note. OG Luxe tastes of tropical peach, citrus and warm ginger. Both are made to be enjoyed straight from the bottle or poured over ice.
