    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.

    A balance of Carbs, vitamins and Electrolytes to give your body all it needs to perform.

    All Styrkr products have been made specifically with athletes in mind and tested in the toughest conditions before going to market. Our gels and drink mixes give you everything you need to perform at your best and nothing that you don’t.

    How many electrolytes do I need?

    During intense activity your body loses electrolytes through sweat. This is dependent on heat, intensity and how heavy a sweater you are. You lose Potassium, Sodium, Magnesium and Calcium during intense activity and it is particularly important to replenish your Potassium and Sodium levels. Our quad blend formula mimics the ratio found in sweat to replace exactly what is lost helping you sustain power and avoid muscle irritation. Follow this chart for SLT05 intake recommendations.

    Any questions we haven't answered?

    How do I use SLT05 Caffeine+ hydration electrolytes?

    Powder sachet to be mixed with 500ml of water.

    SLT05 Caffeine+ is best consumed before and during intense activity and combines synergistically with other Styrkr products as part of a flexible fuelling strategy.

    Why do I need electrolytes?

    For activity over 60 minutes – or in hot conditions – it’s important that electrolytes are used to hydrate. Dehydration increases usage of muscle glycogen and decreases blood volume and digestive function, none of which are beneficial for endurance activity.
    SLT05Caffeine+ helps replace the electrolytes lost in sweat. Water alone can cause bloating, reducing the desire to drink and fluids not being replaced properly.
