EFS-PRO’s primary carbohydrate is a special high-glycemic branched-chain cyclic cluster dextrin (CCD) that stimulates fat oxidation for energy, preserving glycogen stores so you’ll have reserves to capitalize when others are hitting the wall.
Cyclic cluster dextrin is one of the lowest-osmolality carbohydrate sources available and is 100% soluble in water, so it can be mixed at stronger concentrations and still be absorbed quickly and easily, making EFS-PRO the only caloric intake you need to see you through anything from a crit to a century or even a full 140.6-mile triathlon.
Suntheanine® L-theanine is a mind-over-matter compound for maximizing your brain’s control over exercise performance.
The brain plays a key role in endurance. Keeping your brain in the game strengthens your resolve at those decisive moments that can make the difference between success and failure.
This means you can dig deeper into your reserves and react better when everyone is suffering, because you’ll be less influenced by that little voice inside your head that’s screaming at you to stop.
EFS-PRO now contains Pharma GABA®, a patented form of the amino acid GABA, to help you get the most out of every stride or pedal stroke when suffering ramps up and things get serious.
The GABA supplied by PharmaGABA® is a major neurotransmitter that your brain uses to balance out stress and—in the context of endurance sports—it allows you to push past your perceived maximal exertion and closer to your true maximum exertion for longer periods of 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.
