Why people switch from coffee

Coffee-level caffeine.

135–150mg of natural caffeine per cup — about 3× normal tea, comparable to a strong cup of coffee.

Zero jitters.

Every cup is paired with L-Theanine, an amino acid that takes the sharp edge off caffeine. The energy is smooth and focused.

Easy on your stomach.

Tea is roughly half as acidic as coffee. No reflux, no IBS flare, no morning rush to the bathroom.

6–8 hours of clean focus.

Caffeine + L-Theanine release energy gradually. One cup carries a full work block — no afternoon crash, no 4 PM refill.

No jitters, no crash — Zest tea lifestyle flat lay

Zest fits the rest of your routine.
