Approved by athletes, driven by science

All Styrkr drinks, gels, salts and bars 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.

Rapid energy

Carbohydrates are your body’s primary energy source and more can be absorbed per hour when they come from dual sources.

Easy digestion

Styrkr drink mixes, gels and bars contain two transportable carbohydrates at a ratio of 1:0.8 for rapid energy and easy digestion.


Our products hit your PBs hard, not your pockets delivering 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 either.

The Ultra Nutrition Box contains...

Energy Drink Mixes

6x MIX90. Drink powder designed to sustain strength and improve performance.

Engery Gels

2x GEL30, 2x GEL30 Caffeine+, 2x GEL30 Nitro+. Dual-fuel gels that give a crucial energy boost when you need it most.

The Ultra Nutrition Box
Electrolyte Powders

1x SLT05 box, 1 x SLT05 Caffeine+ box. Quad-blend electrolyte powders to keep you fully hydrated.

Energy Bars

2x BAR50 Dark Chocolate, 2x BAR50 Date & Almond, 2x BAR50 Apple & Cinnamon. Dual-fuel rice bar that fights fatigue and gives hunger the heave-ho.

500ml bidon

2x 500ml bottles. BPA free bottle designed to optimise your Styrkr drink mixes.

Hungry for more PBs?

BAR50 is a nutritionally complete, high-energy snack that contains a perfectly balanced amount of carbs, proteins, fat and fibre. Revitalising and flavourful, BAR50 boosts energy, combats tiredness and fights flavour fatigue on longer adventures.

Rip the top, feel the rush

There’s no better way to release energy fast: GEL30’s L-arginine and L-citrulline combine to increase extracellular L-arginine levels. The result: more sustained performance for a more sustained period.

For maximum energy, just add water

500ml of it to be precise. Blending at this ratio allows optimal carbohydrate absorption. The L-glutamine reduces blood ammonia concentration, lessening fatigue and improving performance.

Keep on keeping on

Our quad-blend – sodium, potassium, calcium and magnesium – SLT powders replace the electrolytes lost in sweat to keep you hydrated throughout endurance activity and pushing hard all the way to your finish line.
