What Sets It Apart

Looking for nutrition fuel for long days on the trails, mountains, at the gym or the crag? Gnarly Nutrition’s Fuel20 is your all-in-one, vegan-friendly solution. Created with fueling, replenishment and recovery in mind.

Gnarly Fuel20 contains 100 calories per 12 oz serving from sucrose and dextrose, two carbohydrates that are easy to digest during big endurance efforts. Research supports that using a combination of sucrose and dextrose increases carbohydrate absorption during exercise more than when a single carbohydrate, like dextrose, is consumed alone. Increased carbohydrate absorption also means improved fluid delivery and better hydration.

Gnarly Fuel2O replaces the electrolytes you lose when you sweat, supplying 250mg of sodium per serving as well as the electrolytes chloride, potassium, magnesium and calcium. Gnarly Fuel2O also contains HMB, a metabolite of the branched chain amino acid leucine, which helps to minimize muscle protein breakdown, resulting in less post-training soreness and a faster turnaround between hard training sessions and races. Gnarly Fuel2O is available in two caffeine-free flavors – Tropical & Limeade – and one caffeinated flavor – Cherry Cola, that are light on flavor, and delicious.

Gnarly Fuel2O is my all time favorite endurance fueling product. I like all the options, but the Cherry Cola flavor is amazing and my favorite. It's something I can literally drink all day to power long training runs or ultramarathon races, with no fluctuation in energy and no distress on my stomach. It's also NSF certified for sport, so I don't have to worry about it being contaminated with a banned substance - a huge piece of mind! - Dylan Bowman

Delicious & Effective

I was a little hesitant to give the Cherry Cola flavor a try but I’m glad I did! It’s really tasty and offers replenishment as well as a little caffeine boost.

Gnarly nailed the classic cherry cola taste.

I like the ‘Orange Drank’ Fuel2O flavor a lot too, but REALLY didn’t like the Limeade flavor.

I use these products for mountain pursuits on skis and on foot— backcountry skiing, ultra running/training, alpine/crag climbing.

(Would be stoked to get a sample of the Salted Margarita hydrate and Tropical Fuel2O before buying the whole bag. Could not find those samples on the site)

Great electrolyte and carb mix

I used to use a combo of Switchback electrolytes and Maurten Drink Mix 160, but switched to Gnarly electrolytes/carbs a few weeks ago. It tastes great (not too sweet) and is easy to get down. I take this with Gnarly pre workout (stim) and 2before non caffeinated. It's been a great combo so far.

It’s okay

I have only tried a few gnarly products, but I have generally liked the flavors. This one, the lemon lime, is a miss for me. It’s not the worst, but tastes a bit like nothing even with less water.

Tropical Fuel2O is my go-to

Gnarly’s Fuel₂O is a game-changer for me. After signing up for my first 100-mile bike race this summer, this stuff was perfect for long training days and the race itself. Will continue to be a firm believer in Gnarly’s products as a whole, and Fuel₂O. The orange tastes pretty delicious as well. And yes it might taste better cold, but it tastes pretty good all the time too.
