I was optimistic and excited to try this, as I do use water add ins like flavored drops, and electrolyte tablets when working out, I also do milkshakes with collagen powder. I appreciate that this didn’t have added colors, as some of the drops I have used stain if they spill. I used a glass bottle with a lid to shake. I could not get it to stop foaming, even after trying to do half at a time. The powder clumps get trapped in the foam, and won’t combine. I had to have been shaking or stirring this for minutes. All that could have been excused if it tasted good. It does not. I got the watermelon and it tasted like that pink bubblegum(?) flavoring I got in the medicine from the dr as a kid. I tried to dilute it for to see if I could get used the the flavor, but I did not. The packaging was also comically oversized and plastic. I am a fan of economical and eco-friendly packaging, so this also wasn’t a selling point for me. I couldn’t even finish the serving. It was that bad tasting.
