Hi Cheyenne, We're happy to hear Diego was able to help out! Thanks for sharing your experience 😄
I have not been using gainful for very long but I love it. I like the flavors I’ve tried. I love the way it blends and taste. It’s not to thick and chunky and hard to mix. It’s nice and and light. So far very happy overall!

Hi Miranda, We're happy to hear you're enjoying your protein blend! Thanks for reviewing us 😄
I was very quickly responded to about my concern that there was no option for a sugar-free protein powder. My assigned dietitian explained that he could accommodate this need and made sure I would get refunded and a new order placed for the exact same price (including the discount I previously applied). And before I saw this email, I had first noticed I was refunded and was confused, so I emailed support. Someone got back to me promptly and kindly gave me a brief overview and told me to check the dietitian's email.
