Cherry Cola
With flavor I don’t crave it nor hate it. It gets the job done. Good for when needed, maybe not so much for taste alone.

Gnarly Fuel₂O
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

G. I. Distress
I've tried other flavors(non caffeine) and had no G.I. issues, but this flavor(caffeine) gave me G.I. distress (( which hasnt happened before with gnarly products, or caffeine. both times I tried it on a training run, and in my last race. I can't use this kind but would like to get a different flavor cause it is an excellent product.

First time using this product
I tend to shy away from products like this as they cause GI issues over time during cycling. I have been pleased with this product. No stomach issues, sustained energy, and no taste fatigue. I’m going to order more and the new Orange Drank option that was recently introduced for a limited time.
