I've dealt with cramps my whole life, and I got tired of every "solution" either tasting like a science experiment or only fixing half the problem.
Electrolyte drinks assume it's all about minerals. Nerve-calming shots and pickle juice assume it's all about signaling. Neither one is wrong, exactly, they're just incomplete. Cramps don't have one single cause, so a product that only tackles one cause is only ever going to work some of the time.
Firmline started as an attempt to build the thing I actually wanted for myself: something that covers more than one cause of cramping, in a stick pack I could mix into my day without dreading the taste. Not a vinegar shot you choke down mid-workout. Not a chalky mineral drink. Just something that works, that tastes good, and that fits into a normal routine, whether that's first thing in the morning, before a workout, or right before bed.
Cramps don't just hit athletes either. Anyone who's been woken up by a leg cramp at 2am knows it has nothing to do with how fit you are. So Firmline was built for anyone who cramps, not just the gym crowd.
That's the whole idea behind the name too: a firm line is one that holds steady instead of seizing up. That's what we're going for, every stick, every day.
