First Endurance EFS PRO Drink Mix

An upgraded experience to the already trusty EFS Drink Mix. 

EFS PRO

It’s no secret that mixing up the right amount of electrolytes, fuel, and mental energy during your super hard and/or hot training efforts without triggering a hefty gut punch is a rare art...one that most serious athletes spend countless frustrating hours perfecting.

What if you could literally just MIX & GO and KNOW that you’re getting more than double the electrolytes to keep you hydrated and cramp-free, fast-acting fuel that’s easy to digest.

That's EFS PRO.

What's the Difference? 

With an unparalleled amount of electrolytes included in each scoop, a scientifically advanced fueling system.

EFS-PRO is designed to be mixed at higher concentrations and still be absorbed quickly.  It’s easier on overworked GI tracts, and it boosts uptake of other critical performance nutrients like electrolytes – a force multiplier you'll notice the first time you use it.

Here’s what makes it so magical:

Unrivaled electrolytes, yet tastes good enough to drink ALL DAY.

EFS-PRO’s 1,115mg 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 and 380mg of sodium, EFS-PRO still tastes good, which—we admit—is something we couldn’t always say about their previous mixes. There’s no need to lighten the concentration and substitute with electrolyte tabs just to make it palatable or stave off sweetness fatigue. Like many of you, we came to enjoy and even crave the salty flavor of previous endurance mixes; however, the new EFS-PRO’s reworked flavor profile eliminates the need to acquire a taste for it—it just tastes good.

 

Bioavailability for the best Ability

EFS-PRO comes with 60g of carbs per serving and utilizes Optimal Absorption Technology, which means every ingredient is selected and portioned to deliver more carbs, electrolytes and other essential nutrients without causing GI distress. We insist on ingredients like Cyclic Cluster Dextrin (CCD) carbs, which prevent distress even at high concentration, and DiCalcium malate and DiMagnesium malate, two unique mineral sources that boost absorption rates by 20 to 100%.

EFS-PRO also includes sodium citrate, which reduces stomach acidity to further ease absorption, and citric and malic acids to encourage oxygen uptake and production of ATP (the body’s energy source), helping your cells use the fuel once it’s delivered.

Feed Fave: Lemon Lime

Here's what our athletes have to say...

After 17 hours of pounding 3 scoops per hour, the taste stays perfectly subtle and desirable. Steady energy and zero stomach bloating, goes down like plain water - amazing. Ran 17+ hours on an exposed ski mountain on a very hot and sunny day, and I am a huge sweater. But the sodium and lytes in this were all I took in, and I performed above and beyond expectations, no low points in energy, no cramps, remained well hydrated and in very high spirits mentally. Can't imagine some people have to fiddle with electrolyte pills, SO much easier to have it all in the drink. This is the best drink mix I have ever used, and I've used so many different ones…”

-Todd 

“Previously, I used gels in addition to hydration for fuel. I narrowed my gel flavor choices down to a handful of flavors that caused the least amount of GI issues, and I assumed this solution was the best choice to fuel these events. Well this past year, FE sent me some samples of EFS PRO with a shipment, and I tried them out and I’m totally amazed. I’ve had zero GI issues with this product and use it as my sole hydration and fuel for long runs. This makes it much simpler logistically and the performance is the same or better to boot. In addition to being easy on the GI tract, the flavors are also good and don’t taste overly sweet”

-Dallas

“Hands down the best balance of supplements to keep you going! They call it PRO for a reason, you turn PRO when using this mix. I used this mix on a 100 mile race and performed above my expectations.”

-Johnny

EFS-PRO takes the guesswork, headache, cramping and GI upset out of the equation for you so that you can simply mix, drink, and keep on pushing, all day, in sweltering heat... they got you.
