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.

Tastes great. Performs even better

I've been riding and racing bicycles for over 25 years. I feel like I've tried everything under the sun looking for the best performance and hydration advantage... but it has to taste good too. Gnarly Fuel2O Tropical, is the stand-out winner for me. I've mixed it both minimal and extra rich based on my caloric need/exertion level and the taste is spot on every time. I LOVE the individual packs to put in my jersey pockets for longer rides that require refills along the way.

Only good if cold

The flavor is good if it's cold but on long mountain bike rides my water bottle gets warm.

I felt like the carbs and electrolytes were sufficient for my long mountain bike rides. It was simply the flavor I didn't like. I'll try another flavor of this product next time. Too bad they don't send out sample packets to taste before purchasing.

Hi Nathan! Sorry to hear you didn't enjoy the flavor of your Fuel2O. Hopefully you'd like one of our other 3 flavors.

We do offer individual sticks for purchase on our website if you're interested. They are a little less committing if you're wanting to try it out. If you have any questions or need assistance, don't hesitate to reach out at contact@gognarly.com.

Again, so sorry you didn't enjoy the flavor. Hopefully we can find you a flavor that meets your needs and your taste preferences!

Limeade is Delightful

I’ve really been enjoying the limeade flavor. I’ve been drinking another brand’s lemon and it was just really sweet with a hint of phony lemon taste. This stuff is legit tasty and almost taste like real limeade.
