ATHLETE-APPROVED, ALL-IN-ONE SPORTS FUEL: Styrkr’s GEL50 energy gel offers an advanced, scientifically researched formula with 50g of carbohydrates and essential amino acids (L-citrulline and L-arginine) to help you go harder for longer. Well-renowned cyclists, triathletes, and runners use Styrkr products to fuel their training and events because they deliver when it matters most.
SUPPLIES MAXIMUM CARBOHYDRATES: During exercise, carbohydrates are your body's primary energy source, and absorption rates increase when they come from multiple transportable sources. Styrkr’s GEL50 carbohydrate gel uses a dual-carb system of maltodextrin and fructose (converted to glucose in the liver), providing 50g of carbohydrates to help you reach the finish line faster.
PLANT-BASED AND VEGAN-FRIENDLY: Styrkr GEL50 is formulated without unnecessary colourants or preservatives, ensuring you get only the highest quality ingredients. Its vegan formulation means you can fuel your performance without compromising your dietary choices. All athletes can enjoy and rely on GEL50 when it matters most to help you reach your potential.
DOUBLE BOOST: L-citrulline and L-arginine work together as an endurance powerhouse. L-citrulline is a precursor for L-arginine, boosting extracellular L-arginine levels. This combination in Styrkr’s GEL50 carbohydrate energy gel helps you maintain peak performance for extended periods, whether that’s a marathon or an ultra-endurance cycling event. Whatever your goals, GEL50 has your back.
GENTLE ON THE STOMACH: pH-balanced with no unnecessary preservatives, Styrkr GEL 50 is easy on the stomach and high on carbs, helping you fuel your training or competitive events without an unfortunate timed bathroom trip.
