Between us, we've spent 15 years working schedules most people would never choose.

Zak spent a decade in oil and gas. 12-hour nights, offshore rotations, weeks where your body clock never gets to adjust. Caitlin spent 5 years as cabin crew. Constant time zones, long-haul nights, early starts stacked on late finishes.

Different industries. The same relentless cost.

We both know the fog.

Not tiredness. Something heavier. The kind that follows you into your days off and won't lift. The quiet distance between who you were before shift work, sharper, more present, and who you are now.

We didn't have a name for it then. We do now. The Night Shift Drain. Your brain burning through the chemicals behind focus faster than it can replace them, because the replacing happens in sleep you're not getting.

Most people who work nights stop expecting to feel normal. They just cope. We did that for years.

Coffee. More coffee. Willpower.

Supplements built for people who slept last night and wanted to think a little faster. Energy drinks that worked for an hour and cost you three.

All of it made for someone else's starting point. Not for a brain already running on empty before the shift begins.

It wasn't one moment. It was the accumulation.

The shifts where we didn't trust ourselves. The days we came home with nothing left for each other.

Slowly it became clear this wasn't just part of the job. It was taking more than it gave back. And nobody was offering anything real to fix it.

We went looking for what we needed and couldn't find it, so we built it ourselves.

A formula made for people working against their body clock. Not for the rested brain that wants an edge. For the drained one that needs to stay sharp at 3am and actually recover on the days off it's earned.

Every ingredient chosen for one question. What does this do for someone who didn't sleep last night?

One capsule, at the start of your shift.

Because we were the people who needed it. And after years of managing on caffeine and willpower, we decided we weren't willing to keep calling it normal.

You shouldn't have to either.
