Don't like the flavor
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.
