Created in collaboration with athlete Truett Hanes, Transparent Labs Endurance Gels deliver fast, efficient energy through a dual-carbohydrate formula of both glucose and fructose, built for optimal absorption and sustained performance.

Each gel provides 25g of carbohydrates from rice syrup, tapioca maltodextrin, and real fruit purée, plus 500mg of taurine. Running Gels support endurance, help delay fatigue, and maintain performance during prolonged effort. The dual-carb system helps stabilize energy levels through the final stretch, while taurine supports muscle function when you need it most.

A clean formula with no unnecessary ingredients or synthetic additives. The formula is designed for easy digestion so you can refuel mid-session without stomach issues. Made for runners, cyclists, and endurance athletes looking to power their performance and manage energy during training, runs or rides.

Why Use Endurance Gels

A dual-carbohydrate blend of rice syrup and tapioca maltodextrin with fruit purée provides both rapid and sustained energy release, helping athletes avoid energy crashes during prolonged efforts.

Clean and Stimulant-Free Formula

Delivers smooth, reliable energy for training any time of the day without the risk of caffeine-induced jitters and gentle on the stomach.

Key Ingredients

Our formulas are made with clean, natural ingredients, with clinically-validated dosages to support health and performance.

Fruit Purée (Banana/Apple)

Real fruit carbohydrates and natural sugars provide a whole-food energy source for sustained performance.

Rice Syrup

Fast-digesting carbohydrate source that delivers rapid, readily available energy during exercise.

Tapioca Maltodextrin

Complex, high-density carbohydrate source that maintains performance without spiking digestion

Taurine

500 mg
Supports endurance, reduces oxidative stress, and aids muscle function during prolonged exercise.

Fruit Purée (Banana/Apple)

Real fruit purée delivers natural sugars alongside fiber, potassium, and antioxidants, offering a whole-food carbohydrate source that supports steady energy release rather than a sharp glucose spike.

Rice Syrup

Carbohydrates are the primary fuel source during endurance exercise, and their depletion is often a limiting factor in sustained performance.

 Rice syrup offers a fast-digesting, single-source carbohydrate that's rapidly absorbed into the bloodstream, helping maintain blood glucose levels and delay the onset of fatigue during prolonged effort.

Tapioca Maltodextrin

Derived from tapioca starch, this complex carbohydrate offers a high-density energy source that digests differently than glucose-based sugars. 

Tapioca maltodextrin provides a complex, high-density carbohydrate source that digests steadily, helping sustain blood glucose levels and delay fatigue over the course of prolonged physical effort.

Taurine

500 mg

Taurine is an amino acid known for supporting endurance and reducing oxidative stress during prolonged exercise. 

It also plays a role in regulating muscle contraction and hydration status, making it a functional addition for sustained physical effort.
