⚡ Questions

Frequently
asked.

How much caffeine in a chew?

+
60mg of natural green-tea caffeine — roughly the same as a half-cup of coffee or a shot of espresso. Two chews are the upper bound we recommend in a 4-hour window.

Why no crash?

+
Every chew pairs caffeine with 100mg of L-theanine, an amino acid found in tea leaves. L-theanine smooths the caffeine curve — you don't peak as sharply, and you don't fall as far. Most folks describe it as "espresso minus the jitters."

Are they keto / sugar-free?

+
Each chew has 2g of cane sugar (just enough to balance the tart fruit). No high-fructose corn syrup, no aspartame, no sucralose. If you're strict keto, two chews still fits most macros.

Can I take them on an empty stomach?

+
Yes — many customers do, especially before workouts. If you're caffeine-sensitive, start with one and see how you feel.

How is shipping?

+
Free in the US for orders over $35. We ship within 24 hours from our facility in Salt Lake City, Utah. Most orders arrive in 2–4 business days.
