The clean caffeine

Guayusa

Steady, all-day energy from a leaf - no spike, no crash

What it is

Guayusa (Ilex guayusa) is an Amazonian holly leaf that Kichwa communities in Ecuador have brewed at sunrise for centuries. It's naturally caffeinated and naturally rich in antioxidants.

What it does

Delivers clean, steady energy. The caffeine comes balanced with naturally occurring theobromine and antioxidants, for a smoother, longer lift than coffee or lab-made caffeine — the kind you feel but don't have to fight.

Why it's in Second9

30mg per can

We wanted energy that fits a long round or a dawn patrol, not a jolt you pay for later. Guayusa gives a calm, sustained rise — no jitters, no crash. 30mg per can, about a third of a cup of coffee.

Will it keep me up?

At 30mg it's a light lift, not a double espresso.
