ELECTROLYTE LEVELS
TO PREVENT CRAMPING
We make a big deal about how EFS more than doubles the cramp-preventing electrolyte content of competing mixes, so it’s significant that EFS-PRO provides even more. EFS-PRO’s 1,400mg of electrolytes per serving are unrivaled across the industry, ensuring untimely cramps aren’t the weak link in your training and racing.
Despite its high electrolyte content, the EFS-PRO’s flavor profile eliminates the need to acquire a taste for it—it just tastes good, with a light sweetness that isn’t so cloyingly saccharine that ingesting it for several hours in a row becomes yet another race-day obstacle.
ELECTROLYTE COMPARISON

GIVE YOUR ALL, ALL THE TIME
Races are won and lost in the moments when you’re so crushed that even the thought of maintaining your target pace or throwing a shift lever can make you want to stop running or climb off the bike. But unless you’ve completely bonked, that’s just a thought, so EFS-PRO includes Suntheanine® (also in EFS) and PharmaGABA® (unique to EFS-PRO) to silence that pain-induced panic. In clinical research, both ingredients have been shown to boost alpha brainwaves and promote whole-body antistress, relaxation, and calming effects while maintaining cognitive functions under stress.
Outside of the clinic, we call that mental toughness, and anyone who’s suffered in competition knows that it’s often the difference between either digging deeper through the pain to find a response or watching the gap grow as the race leaves you behind. Our precise dosing of Suntheanine® and PharmaGABA® make EFS-PRO the most advanced endurance nutrition and hydration mix available. They help you get the most out of every stride or pedal stroke, even—or especially—when your legs are screaming at your brain to stop.
