Powerful hydration your body needs

More efficient hydration

SLT07 rapidly replaces the electrolytes lost in sweat, meaning you can perform at your peak for longer.

Improved bioavailability

Bioavailability is the rate that something is absorbed into the bloodstream to elicit its effect on the target area of the body. Effervescent tablets have a high bioavailability and high absorption rates.

Quad-Blend hypotonic

Designed to be used as a supplement to help restore electrolyte balance in the body after intense physical activity and dehydration.

Increases water intake

Helping athletes meet their daily water consumption goals, effervescent tablets can be a useful tool for promoting overall health and wellness.

Practical and on-the-go

Effervescent tablets provide a convenient and versatile option for people who dislike or struggle to swallow tablets, as they can be used anywhere and only require water.


Our products are proudly 100% vegan and non-GMO, guaranteeing the highest quality ingredients for your health and well-being.

What goes into Styrkr hydration kit?

The perfect hypotonic formulation

Quad-blend electrolytes

Our ‘quad-blend’ electrolyte mix perfectly mimics the profile of human sweat to ensure that vital salts are constantly replenished.

Gentle on the stomach

Once dissolved, the pH of the final solution transits quicker from the stomach to the small intestine reducing any irritation.

Your body, your dose

During vigorous activity and in hot conditions, some of us sweat more and saltier than others. Our effervescent tablets are dual-dosage. Use a whole tablet if you sweat heavily or are exercising in hot conditions. If you don’t sweat a lot and the conditions are mild, just use half.

Effervescence done right

Not only are our rehydration tablets developed by professional sports nutritionists and tested by athletes to make sure they do what we say they do, all SLT07 ingredients are vegan, non-GMO, gluten-free and responsibly sourced.

“We always say we listen to our customers and SLT07 is further proof of that,” says Styrkr founder, Christian Sanderson.
“People enjoy the ease and convenience of effervescent tablets and wanted the Styrkr blend but in that format. So we set to work to make it happen.”
