Product details
01 At a glance
  • Immediate mental lift
  • Calm, steady focus
  • Supports attention & accuracy
  • Nature’s duo from green tea
02 What it is

Caffeine wakes you up fast, but it can also bring jitters and an energy crash. L-Theanine, an amino acid found in tea leaves, smooths out those side effects by promoting calm, centered focus. Combined, they create a natural synergy—like the balance found in green tea—that delivers clean, lasting energy with sharper focus and fewer downsides.

03 What to expect
Within 20–30 minutesbrighter alertness and concentration, without the edge of caffeine alone.
Up to 4–6 hourssteady, jitter-free focus with a smooth taper—no harsh crash.
EvidenceHuman trials show that caffeine + L-theanine improves attention, accuracy, and mental performance while reducing jittery feelings (PubMed: PMID 21040626 ; PMID 18681988 ).
04 How it works

Caffeine blocks adenosine, the neurotransmitter that makes you feel tired, and boosts alertness and reaction time. L-Theanine promotes alpha brainwave activity, linked to relaxed attention, and modulates excitatory signaling. Together, they balance stimulation with calm for sharper performance.

05 How to use
