    Who it's for
    Runners and endurance athletes who are low-salt sweaters or prefer to manage sodium intake separately from their carb/hydration strategy. Also suits those whose palates fatigue from sweet or salty flavors late in long efforts.
    What people are saying
    Hosts consistently praise the very light, not-too-sweet flavor and how easily it mixes with water. It's commonly used alongside gels or other nutrition as a carb supplement, not a standalone fuel.
    Worth noting
    Multiple hosts flag that it's carb-only, so it's not a substitute for electrolyte products for heavy or salty sweaters. Dosing varies — notes mention both one and two scoops per bottle depending on individual needs.

    Robyn Lesh's review

    I use the carb only drink mix because I am a low salt sweater and prefer to get my salt elsewhere. Precision drink mix has a very light taste and isn't too sweet. A really nice simple product. I mix at 30g/bottle to supplement my gels.

    Caroline Alcorta, Professional Trail Runner

    Did a sweat test last year, apparently I'm not a super salty sweater! But I am a heavy sweater! So I need to be mindful and efficient about my water + nutrition intake with longer races.

    Two scoops of this in a 500 ml soft flask with water is all I need fluid and electrolyte-wise to start a sub-ultra race. Plus it gives you an extra 30g of carbs!

    I really like this late in a race or long run because it is high carb and has no flavor. After awhile the palate get tired of all the sweet and salty stuff and this really helps with that.
