I have been using Vega One All-In-One for years now. I was drinking Carnation Instant Breakfast but one day realized how much sugar I was putting into my body. A trusted health food store employee suggested this as a alternative. It was a bit of a challenge at first, going from something with so much sugar to this, but now it tastes good and keeps me full for a while.
SIDE NOTE: I received a jug of this with 5 holes punched into the top of the seal and it completely freaked me out. I had Amazon send a replacement and it too had the holes. I reached out to Vega One and this was their response: "Thanks for reaching out! Yes, I can definitely see how the ventilation holes could be alarming as they slightly larger and more noticeable than before. We’ve always had ventilation holes in our seal, though it seems our manufacturer is likely using a new machine so they are in a more noticeable position and are slightly larger as I mentioned. The pin sized holes are completely characteristic of the vented liner on our tub and are meant for circulation."
