What we think

Nothing can kill a good ride or run quite like leg cramps… and nothing can kill cramps quite like EFS...

If occasional cramping is a major frustration for you and you want an easy, reliable solution to prevent cramping while training that doesn’t require a degree in biochemistry, then EFS Sports Hydration is exactly what you’re looking for…

Here’s why…  

If you’re like most serious athletes, you’ve probably spent countless aggravating hours attempting to calculate your specific electrolyte, hydration, and fueling needs on any given workout by mixing a concoction of various products and supplements at precise intervals to match your estimated sweatage and wattage outputs based on a number of hypothesized factors… (eyes glaze over yet 🥴?)...

But guesswork and estimation can only take us so far. So what most of us end up doing is crossing our fingers and hoping we haven’t mixed up a major gut punch, a serious bonking issue or legs that end up screaming in pain from dehydration… 

Which is why we (and countless athletes) are soooo excited about First Endurance EFS Drink Mix, now reformulated to TASTE GOOD

If you want to...

✅ Improve mental toughness & sharpen competitive edge

✅ Prevent cramping & hydrate FAST

✅ Get immediate & sustained fuel when you need it most

Then EFS is for you

 

Here’s what makes it such a great all-in-one solution:  

🏅It includes everything you need to fuel your workout

EFS provides the ideal blend of carbohydrates, amino acids, antioxidants, and electrolytes to fuel your working muscles and improve your endurance capacity during exercise. This drink mix uses a combination of glucose and sucrose, which helps increase absorption and utilization during exercise. Not to mention, it’s a 7% carbohydrate solution so it’s low concentration enough to reduce risk of stomach issues.


🏅It's THE solution to cramping

Using the latest amino acid technology, superior mineral bioavailability, and the addition of Malic acid, EFS refuels and rehydrates better than ever before. It has a unique Total Electrolyte Blend that provides the highest electrolyte content available (1160mg of all 5 essential electrolytes per serving), so you won’t need to add anything else to this mix. If you’re going for Gold and pushing extra hard and/or training in the sweltering summer heat… check out brand-new EFS PRO for the ultimate hydration solution  


🏅Drink it all day long with no issues

We find you can drink EFS again and again without getting sick of it, or having stomach issues. It’s light and easy to digest and has just been reformulated so that the flavor is much better (old formula was okay, but quite salty. New formula is much tastier ).


🏅Now formulated for mental toughness

Now EFS really is your ultimate all-in-one sports mix as the new formula.. includes the addition of Theanine (a chemical which helps boost Alpha brain waves while decreasing Beta brain waves) so you’ll have the mental toughness it takes to push your body to the limits when it matters most.

PERFORMANCE BENEFITS

  • Theanine boosts mental toughness to help you push through suffering

  • Industry-leading electrolyte content—nothing is better at preventing cramps

  • Carbs from multiple sources provide immediate and sustained fuel

  • 7% osmolality ensures bioavailability and reduces GI distress

  • Citric and malic acids promote oxygen uptake and energy production

  • New taste profile eliminates the flavor vs function compromise

How We Use It

We use this product during workouts and competition to keep our bodies hydrated with all the nutrients necessary for optimum performance. We recommend consuming one serving per half-hour of intense training.

It’s easy to mix, and won’t leave clumps. It also makes packing for your ride or run a lot easier since you won’t need to fumble with a bunch of gels, chews, electrolyte sticks etc. Just bring enough water and EFS to keep you going for a cramp-free, high energy training sesh.

I recommend this product
EFS rules!

No cramps, long lasting endurance, decent taste, no food coloring, low cost & mixes well. What else can be said? I have been an avid mountain biker since 1990 and have consumed many pre-ride products for improved performance. None have delivered on their promises quite like EFS, NO CRAMPS!! I admittedly party often and end up answering the early morning calls of "are you riding dude" with a ugh, "I'm super hungover but sure". Until I found EFS I would just suffer brutal cramps usually culminating in a fantastic auger (see wreck). There is nothing quite like getting a quad cramp on a 8' high skinny. Anyways, EFS rules!

OMG - no more leg and back cramps, even while training in the Texas heat! My coach suggested EFS, and I am so very glad he did!

I train Brazilian Jiu Jitsu and it's perfect during rolling when I'm expending energy and get dehydrated easily. I mostly take it to prevent cramping and it works very well. I was training and kept getting foot cramps and my instructor made me an EFS drink and they went away immediately. Highly recommend.
