LEVELEN™ Lemon-Lime Electrolyte Mix
Made to your Level from your sweat test, absorbed via glucose so your body actually absorbs it.
★ Don't know your level? Take a sweat test.
Clean, crisp lemon-lime. Formulated to your tested Level (900 to 1,500 mg sodium per liter), carried by dextrose for real absorption. Your number, your flavor.
How it works
This mix is built for your Level.
Not tested yet? Start with a sweat test. It sets your Level, 3 to 5, and we build this formula to match how salty your sweat runs.
Take the sweat test
Wear the patch through one normal workout and mail it back postage-paid. No lab visit, no change to your routine.
Get your Level
Your sweat test determines your LEVEL, based on how salty your sweat is. It comes down to your genes and what you're doing.
Fuel to your number
Drink the mix made for your LEVEL. The right electrolytes, carried by glucose so your body absorbs them quickly and efficiently.
The details
Read the fine print. We did.
What's inside
Electrolytes set to your Level, carried by dextrose (glucose) so your body actually absorbs them. Sodium by Level: L3 900, L4 1,200, L5 1,500 mg per liter.
The science
How salty your sweat runs is genetic and sets your Level. Your sweat rate, driven by heat and intensity, sets how much you drink. Between a light sweater and a heavy, high-salt sweater, total electrolyte loss can differ more than 200x, which is why a single generic scoop can't serve everyone.
What's not inside
- No one-size-fits-all scoop
- No zero-calorie gimmicks that end up in the toilet
- No guessing which electrolyte load you actually need

Testimonials
What athletes say.
Real athletes, real results, in their own words.
Through a recent Sweat Test in Kona, we were able to tweak my fuel plan to best my 2009 time by 40 minutes and pick off all but one of the ladies in front of me.

Sandy (Dr. Fowkes Godek) sweat tested me and recommended LEVELEN Level 5. The best part: my cramps were immediately gone.

At my first Leadville Trail 100 using LEVELEN, I completed the 104 mile course, with 12,500 feet of elevation gain, in 11:37:52 without a single cramp.

The sweat test kit is very simple and straightforward, and the results were clear. The LEVELEN team is all about the science and the fine-tuned needs of athletes.

I incorporated LEVELEN 4 into my long distance training plan and the results have been great. For the first time, ‘the wall’ never came.

Since I started using LEVELEN 3 before my workouts, I have seen a big difference in my energy level and my performance.
