Science-backed energy gel recipe app. Create, edit, share and discover community DIY energy gel recipes for endurance athletes.
What is GelForge?
Create Perfect Energy Gels
GelForge empowers endurance athletes to create personalized energy gel recipes tailored to their specific nutritional needs. Whether you're training for a marathon, century ride, or triathlon, our app helps you optimize your fueling strategy with carbohydrate formulations.
Say goodbye to expensive commercial gels that might not suit your taste or stomach. With GelForge, you control every ingredient, save money, and fuel your performance with recipes proven by sports science.
The Science of Carbohydrate Intake
Endurance performance depends on proper carbohydrate fueling. Research shows athletes should consume 30-90g of carbs per hourduring exercise lasting longer than 60 minutes, depending on intensity and duration. Elite athletes can consume up to 120g per hour for maximum performance.
Not all carbohydrates are equal. GelForge helps you balance different sugar types including dextrose, maltodextrin, fructose, and sucrose to maximize absorption and minimize digestive issues. Your tolerance improves with gut training over time.

🔬 The Critical Glucose:Fructose Ratio
One of the most important aspects of energy gel formulation is the glucose to fructose ratio. Research demonstrates that the optimal ratio is approximately 2:1 (glucose:fructose) for maximum carbohydrate absorption. Elite athletes with extensively trained guts may tolerate ratios closer to 1:0.8, but this requires progressive gut training.
- Glucose and fructose use different intestinal transporters
- Combined intake can exceed 60g/hour absorption limit
- Reduces risk of gastrointestinal distress
- Improves endurance performance and energy delivery
- Gut training allows higher fructose tolerance over time
- Total carbs per hour input
- Customesed glucose:fructose ratios (Advanced/Pro feaeture)
