I am a big energy chew fan; gels make me sick, and bars are too hard to eat during serious mountain biking. So naturally I've tried just about every brand and flavor. After trying these chews I have a new favorite!
In my book: Skratch Labs > Honey Stinger > Clif Bloks > Pro Bar Bolts > Bonk Breaker Chew > GU Chomps > all others
Of the two flavor options I prefer the raspberry, but both are tasty and easy to eat.
OSMO is easy to drink and I like the new tubs and especially the single serving packs. However, neither the blackberry or orange are particularly delicious unless they're ice cold.
I first used OSMO at the recommendation of my teammates and while I do think they're science is solid I much prefer Scratch Labs because it tastes better and mixes more easily. That being said OSMO is definitely my second favorite mix.
