    Expert Review

    Easier on the gut than other products, milder flavor to avoid cloying sweetness, and more usable carbs and sodium numbers. I also love the Mandarin and Tropical flavors! I stash a few single serving packs in my drop bags as treats!

    This product is for…

    Endurance athletes — especially ultrarunners and marathoners — using it for events or training runs over two hours. Notes repeatedly cite it as a race-day staple and drop-bag go-to.

    Worth noting…

    One host cites 25g carbs and 310mg sodium per serving as key numbers. Usage reported as high as 10–12 scoops per 20-mile loop in ultras, and it's commonly served at ultra aid stations — making training familiarity worthwhile.
