Somewhere past the third or fourth hour of a long effort, the bottle you've been drinking stops appealing to you. You put off the next serving, then skip one, and your carbohydrate intake quietly slips until your legs feel it. Maurten calls this flavor fatigue, and it traces the problem to over-exposure — repeated consumption of the same taste or texture, even a neutral one, erodes your appetite to stay on plan. The Addition line exists to interrupt that cycle. Each box holds 6 single-serve sachets that drop straight into your prepared Drink Mix to change the taste without meaningfully changing the fuel underneath.

Maurten built its reputation on flavor-neutral products with short ingredient lists, keeping the focus on fuel delivery. Additions follow that same logic — the sachets contain only maltodextrin and natural flavoring, which means they carry no animal-derived ingredients and are vegan-friendly. There are no artificial colors or preservatives, and the sachets are Informed Sport tested. Each one carries just 1.6 to 1.9 grams of carbohydrate and 7 to 8 calories, so nutritionally it's a non-factor — the point is taste, not fuel. One sachet added to a bottle of Drink Mix 160 or 320 gives you a different drinking experience in Apple, Cola, Menthol, or Orange, all while leaving the function of Hydrogel Technology intact.

That last point matters more than it might seem. Additions were engineered specifically for compatibility with Hydrogel Technology, so they don't interfere with the reaction that turns Drink Mix into a hydrogel once it reaches your stomach. The hydrogel forms the same way, delivers carbohydrates the same way, and performs the same way — the only thing that changes is the taste profile of your bottle. Carb and sodium levels stay put; you just get more range. Flavor fatigue shows up differently for every athlete — mid-race for ultra and trail runners, across a training block for cyclists, on the long bike leg for long-course triathletes. Additions give you a way to interrupt that pattern by changing how your fuel tastes rather than what you're fueling with.... Read More
