League is a new kind of sports nutrition brand — built from the ground up for developing athletes.
No junk. No gimmicks. Just fuel that works in the chaos — from 5AM alarms to late-night recoveries.

Built for This Stage

Youth sports today look more like the pros than the community leagues many parents grew up in — with 5AM alarms, back-to-back practices, and weekends built around tournaments. But walk the aisles, and there are still only two choices: kids’ drinks full of sugar, or adult shakes packed for bodies that stopped growing years ago. Neither was made for athletes in this stage.

As a parent, this was the gap I faced every day: how to fuel my athlete in a way that was healthy, effective, and real. Too often the options were sugar water that gave a jolt but nothing else, or formulas that overshot on ingredients they didn’t need. And with hectic schedules — late homework, long drives, drive-thru dinners — getting it right was even harder.

Meanwhile, the pressure never let up. The competition is intense. These athletes want to perform at their best. And nothing out there respected both performance demands and the realities of growth.

That’s why we built League. Fuel made for this exact moment: clean energy that works, recovery that supports what’s next, hydration that keeps up, and nutrients that matter for developing athletes.

League is more than nutrition. It’s culture. It’s recognition for the grind no one sees — the early alarms, the long drives, the homework in the car.
