  • 25g Sucrose + Dextrose: Two carbohydrate sources that use different transport proteins to move from the gut into the bloodstream — lets your body absorb more total carbohydrate per hour than a single source alone, while minimizing gut distress.
  • Full electrolyte profile: 250mg Sodium, 100mg Potassium, 125mg Calcium, 90mg Magnesium, plus Concentrace® Trace Minerals to replace what you lose through sweat.
  • 125mg HMB (β-hydroxy-β-methylbutyrate): A leucine metabolite that helps minimize muscle protein breakdown during long efforts — supports faster recovery between hard training sessions.
  • 2mcg Vitamin D3 as Vitashine®: The vegan D3 form to support immune function and muscle function during extended training.
  • Three flavors: Cherry Cola (with caffeine from Green Tea Leaf), caffeine-free Limeade, and Salted Orange with extra sodium for heavy sweaters.
  • Built for efforts over 90 minutes: Where you need both fuel and electrolytes — endurance runs, big rides, alpine days, and long training sessions.

Gnarly Fuel2O is the endurance fuel built for the long day out. Where Hydrate replaces the electrolytes lost in sweat, Fuel2O adds significant carbohydrates plus HMB to replace calories, prevent muscle breakdown, and keep you moving through efforts over 90 minutes.

Fuel2O uses a Sucrose + Dextrose carbohydrate blend that leverages multiple gut transport pathways -- letting your body absorb more total carbohydrate per hour than a single carb source alone, while minimizing gut distress. This is standard endurance-nutrition science, the same principle behind glucose-fructose blends used in pro-level gels and drink mixes. The full electrolyte profile replaces what you lose in sweat, and 125mg HMB helps preserve muscle during long efforts when your body starts breaking down muscle protein for fuel.

Key features of Gnarly Fuel2O:

• 25g carbohydrates from Sucrose + Dextrose blend for sustained energy and dual-pathway absorption
• Full electrolyte profile: 250mg Sodium, 100mg Potassium, 125mg Calcium, 90mg Magnesium
• 125mg Calcium HMB to minimize muscle protein breakdown during long efforts
• 2mcg Vitamin D3 as Vitashine® (vegan form)
• Concentrace® Trace Mineral Complex
• NSF Certified for Sport, vegan, gluten-free

Mix 1 scoop with 12-16 oz of water. Consume 1-2 servings per hour during long efforts. Cherry Cola includes caffeine from Green Tea Leaf Extract for morning efforts and mental focus. Limeade is caffeine-free, ideal for evening or back-to-back sessions. Salted Orange has extra sodium for heavy sweaters and hot-weather training.

Active Ingredients: Sucrose (25g), Dextrose, Sodium as Sodium Citrate and Sea Salt (250mg), Calcium as Calcium Lactate (125mg), Magnesium as Magnesium Citrate (90mg), Potassium as Potassium Citrate (100mg), Concentrace® Trace Mineral Complex, Calcium HMB (125mg), Vitamin D3 as Vitashine® (2mcg). Cherry Cola adds Green Tea Leaf Extract for caffeine.

Other Ingredients: Tapioca Maltodextrin, Acacia Gum, Citric Acid, Natural Flavors, Stevia Leaf Extract, Silicon Dioxide.

Available in Cherry Cola, Limeade, and Salted Orange. Bag (25 servings) or 20-Stick Box.

Q: What's the difference between Fuel2O and Hydrate?
A: Hydrate replaces what you lose when you sweat -- water and electrolytes. It contains a small amount of sugar to help push water into your cells, but not enough to be a meaningful caloric source. Fuel2O has a similar electrolyte profile, but adds significant carbohydrates (25g / 100 calories per serving) plus HMB. Use Hydrate for shorter or lower-intensity efforts where you don't need calories. Use Fuel2O for anything over 90 minutes where you need both fuel and electrolytes.

Q: Why is there so much sugar in Fuel2O?
A: 25g of added sugar (100 calories) sounds like a lot in a general nutrition context, but it's exactly what you need during endurance exercise. The average person burns 500-600 calories per hour running, and replacing those calories mid-effort is the only way to avoid the bonk. Consuming 1-2 servings of Fuel2O per hour during long efforts replaces those calories while simultaneously replacing electrolytes.

Q: Why sucrose and dextrose specifically?
A: These two carbohydrates use different transport proteins to move from the gut into the bloodstream. Using both together lets your body absorb more total carbohydrate per hour than a single carbohydrate source alone -- while minimizing the risk of gut distress. This is standard endurance-nutrition science: the same principle behind glucose-fructose blends in gels and drink mixes.

Q: What's HMB and why is it in Fuel2O?
A: HMB (beta-hydroxy beta-methylbutyrate) is a metabolite of the branched-chain amino acid leucine. During prolonged caloric deficits -- like long endurance events -- your body starts breaking down muscle protein for fuel, which leads to delayed-onset muscle soreness (DOMS) and slower recovery. HMB helps minimize that breakdown, so you recover faster between hard training sessions and races.

Q: Which flavor should I choose?
A: All three have identical electrolyte and carbohydrate profiles, so the choice is about caffeine and personal preference. Cherry Cola includes caffeine from green tea leaf extract -- best for morning efforts or when you want the mental focus boost. Limeade is caffeine-free, ideal for evening or back-to-back efforts where added stimulants aren't wanted. Salted Orange is also caffeine-free but formulated with extra sodium -- the pick if you're a heavy sweater or training in high heat.
