Okay, as for flavors specifically, The chocolate flavor is a fail so far, it’s basically like U/U, except it has sweetener I can’t even taste.
Berry, is okay.
Vanilla is decent, probably my favorite of the sweetened bunch.
U/U is the winner in my mind. All of the flavored Huel tastes pretty bland. Not an issue, but not a benefit exactly.
I like the choc mint flavor boost, but i feel you’ve got to use more than directed. I mean, you don’t have to, but it tastes kinda bland like the huel if you don’t.
A big winner, (with way too many calories) is adding 2 tbs pb powder, 2 tbs choc protein powder, and milk. milk i’d say like 1/3 - 2/3 cup per scoop huel. almond milk would probably be better due to the kcal. top off with water, & add other stuff too if desired. I found if i used 1 huel scoop, with the protein & pb, & a little milk, it came out to about 400 kcal (but only 1 scoop huel). Not sure if it’s worth it, but it tastes good! The milk & protein powder has sugars, so it helps sweeten the huel another benefit of the milk if it adds fat, which the pb powder lacks. I haven’t tried adding coconut yet, but it’ll likely require a blender, which i’ve avoided so far.
Hope my posts weren’t TOO wordy! Good Luck!
