Endurance Fuel, Backed by Science.

All Styrkr drinks, gels and salts have been specifically engineered to produce unique effects in the body – specifically, the bloodstream – that reduce overall fatigue and energy expenditure while maintaining power and increasing output throughout endurance activity.

Complete endurance fuel

We don’t just give you the most effective carbohydrate fuelling, our active ingredients like L-glutamine reduce the accumulation of blood ammonia concentration during exercise, lessening fatigue and boosting your performance.

Perfect carb ratio

Styrkr drink mixes and gels contain two transportable carbohydrates – maltodextrin and fructose – at a ratio of 1:0.8 to improve the exogenous carbohydrate oxidation rate and cause the least amount of gut discomfort compared to ratios of 1:1.25 and 2:1


Our products hit your PBs hard, not your pockets. FACT: Styrkr drink mixes, gels and salts costs less per unit than our dual-carb competitors. Our products deliver maximum carbohydrates in an industry leading price to weight ratio.


All our products are vegan society approved and made with natural ingredients.You’ll not find any colourants or preservatives in our drink mixes, gels or salts either. With Styrkr, it’s natural ingredients all the way to the finish line.
