“I initially tried the frosted flakes and fruity cereal (fruit loops) collagen flavors. The Frosted Flakes is super delicious - but I wasn't a huge fan of the fruit cereal version (which tasted very artificial and almost plastic-y). I couldn't down it and must say customer service was quick and kind in helping with that. Since then, I've tried the peanut butter cup and the marshmallow cereal flavored collagens. I'd say favorite is still frosted flakes with the marshmallow being a close second, and the peanut butter cup falls more similar to the fruity cereal flavor since I got a strongly artificial and metallic taste from trying that one. Mixability is great, just needs some solid whisking in hot drinks, cold drinks, and oatmeal. All flavors are SUPER sweet - borderline too sweet - but I'm also not used to sucralose, which is the sweetener used in these. Price is okay if using a coupon or getting a special deal, but definitely wouldn't pay full $40 a tub for only 30 servings. Great marketing and creative product/line, though! I'd get the frosted flakes and maybe try another flavor again if they go on sale :)”
