    Who it's for
    Endurance athletes — cyclists, runners, triathletes — who need a high-carb drink mix without heavy sweetness or saltiness. Particularly suits low-salt sweaters who prefer to source electrolytes separately.
    What people are saying
    Hosts consistently praise the light, not-too-sweet flavor and how easy it is to drink deep into a long effort when palate fatigue sets in. It mixes cleanly with water and is commonly stacked with gels or other nutrition rather than used as a standalone fuel source.
    Worth noting
    Several hosts note it is low in sodium, making it a deliberate choice for low-salt sweaters — heavy sweaters or salty sweaters may need to supplement electrolytes more carefully. Typical usage mentioned is 30g (one scoop) to two scoops per bottle.

    Casey Rowan's review

    I build every race around 90g of carbs an hour, and this is the base of it. Mixes clean, never gets sticky.

    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.

    Meikael Beaudoin Rousseau, Professional Trail & Mountain Runner

    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!

    Robyn Lesh, Pro Trail Running Athlete

    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.

    Lisa Williams, Run/Ultra Endurance Nutrition Coach

    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.
