This is a good example of a product that knows exactly what it is.

It is not trying to be a massive race-day carb bomb like some of the higher-carb mixes or gels, and it is not pretending to be just a hydration tab either.

It sits nicely in the middle as a very usable day-to-day endurance drink, especially for training sessions where you want a meaningful amount of carbohydrate with some electrolyte support, but do not necessarily need to go as aggressive as you would in a big event.

Who it’s for:

Endurance athletes wanting a solid everyday training mix.

Runners, cyclists and Hyrox-style athletes doing longer or harder sessions.

People who want both carbs and hydration support in one product.

Anyone who struggles to fuel properly going into training and needs something easy to get in.

What it does:

Provides 30g of carbohydrate per serving for training fuel.

Uses a dual-carb maltodextrin and fructose blend to support carbohydrate delivery.

Supplies sodium plus other electrolytes to support fluid balance.

Gives you a practical option before, during, or after sessions depending on the length and intensity.

How I’d use it:

I would see this as a very practical daily training fuel.

For shorter sessions, it may be enough on its own. For longer endurance work, it can sit alongside gels or other carbs depending on how many grams per hour you are aiming for.

It also makes sense for those early morning sessions where eating a proper meal is not realistic, because it gives you a quick way of getting carbs and some electrolytes onboard without feeling heavy.

The Science:

Fructose-maltodextrin ratio in a carbohydrate-electrolyte solution differentially affects exogenous carbohydrate oxidation rate, gut comfort, and performance

Study: This study examined carbohydrate-electrolyte solutions using different fructose-to-maltodextrin ratios and looked at exogenous carbohydrate oxidation, gut comfort and performance during endurance exercise.

The paper supports the idea that the carbohydrate ratio in a sports drink matters, not just the total carb content. That is relevant here because STYRKR specifically highlights its 1:0.8 maltodextrin-to-fructose ratio as a key feature of MIX+, aimed at effective carbohydrate delivery with good tolerance.

Post-exercise rehydration in athletes: Effects of sodium and barbohydrate in commercial sports drinks

Study: This study looked at how varying sodium and carbohydrate levels in sports drinks influence rehydration after exercise-induced fluid loss in athletes.

The findings support the importance of sodium and carbohydrate in sports drinks when the goal is to restore fluid balance after exercise. That fits well with MIX+, which combines carbohydrate with a quad-blend electrolyte formula and explicitly provides 360mg sodium per serving.
