"FUEL has the key things I look for in an endurance product that I’m drinking for hours on end during my training and events: taste, mix-ability, it gives me steady energy and is it easy on the stomach. Whether I’m training for 2 hours or 5 hours, FUEL is formulated perfectly for intense endurance events."

- Natasha Van Der Merwe, Professional Triathlete & Coach



Each serving includes 24g carbohydrates in a precise ratio of 1 to 0.8 Glucose to Fructose, efficiently fueling the ultra-endurance athlete.


Sodium is the main electrolyte responsible for fluid balance, muscle contraction, and cellular communication and is the electrolyte that’s lost in the largest and most variable amounts during excessive endurance exercise and sports. 

  • Each serving includes 300mg sodium in a 1:1 ratio of sea salt to sodium citrate. 
  • Using sodium citrate in conjunction with sea salt allows your gut to tolerate more sodium consumption during training, delivering optimal hydration and electrolyte balance without digestive upset. 


This formula contains the optimal carb and salt ratios to meet the needs of endurance athletes at the highest level per hour without gut distress. Raw Ultra Endurance provides up to 100-120g of carbs in combination with 1250-1500mg sodium per hour.
