TL;DR

• Immediate mental lift
• Calm, steady focus
• Supports attention & accuracy
• Nature’s duo from green tea

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.

What you’ll feel (and when)

• Within 20–30 minutes: brighter alertness and concentration, without the edge of caffeine alone.
• Up to 4–6 hours: steady, jitter-free focus with a smooth taper—no harsh crash.
• Evidence: Human trials show that caffeine + L-theanine improves attention, accuracy, and mental performance while reducing jittery feelings (PubMed: PMID 21040626 ; PMID 18681988 ).

How to use

• Dose: 1 capsule, 1–2 times daily as needed
