This shot is for you if:

✔ You hit a wall between 2–4pm and reach for coffee or sugar to push through ✔ You want clean, sustained energy without the jitteriness or the crash ✔ You've cut back on caffeine but still need a reliable afternoon lift ✔ You do shift work or irregular hours and need energy on demand ✔ You want something that fits in your bag and works in under a minute

✘ If your priority is mental sharpness and cognitive clarity specifically, that's FOCUS.

The science behind the steady lift

ENERGY pairs 60mg of natural caffeine with 200mg of L-theanine, the amino acid found in green tea. The two are studied most closely together: L-theanine is associated with calm alertness rather than stimulation, which is why it is paired with caffeine to take the edge off the lift.

L-Theanine and caffeine, together

A placebo-controlled trial found L-theanine and caffeine in combination improved the speed and accuracy of attention-switching tasks and reduced susceptibility to distracting information, compared with placebo. Read the study on PubMed

A randomised, placebo-controlled study found the combination of L-theanine and caffeine improved task-switching accuracy. Read the study on PubMed

L-Theanine 200mg

A randomised, triple-blind, placebo-controlled crossover trial found that a single 200mg dose of L-theanine increased frontal alpha wave activity and reduced salivary cortisol during an acute stress challenge. Read the study on PubMed Central

A randomised, double-blind, placebo-controlled trial found L-theanine improved attention reaction time, working memory and executive function scores. Read the study on PubMed

A 2025 systematic review and meta-analysis of randomised placebo-controlled trials evaluated L-theanine's effects on cognitive function in healthy adults. Read the review on PubMed Central
