Gainful products taste great. I love that they have individual flavor boosters so you have more than one option for the protein shakes. The electrolyte drink is like a good tasting lemonade. The RDs are responsive and quick with any answers you need.

Thank you for sharing your experience! We're happy to be a part of your health and fitness journey 🙂
Loving it so far! The quiz is what brought me to Gainful, and I'm so grateful that they don’t use a bunch of stupid ingredients (although I only use the protein so I can't speak for all the products). I like the protein, and the subscription model is perfect. I just wish that shipping times were a little bit faster but they do a good job in showing you when exactly it'll get to you and how to plan ahead so you're not left without anything.

Hi Maraya, Thanks for your feedback! We're glad you're enjoying your personalized protein blend🙌
Response is so fast! At first, I honestly had trouble with the website, I couldn't get it to scroll and therefore couldn't see my choices. Glad I persevered. I've added another element for next month so we'll see how that goes. I'm a performer of limited means during this pandemic, but this has satisfied me and I feel supported to care for myself.

Hi Lydia, Thanks for taking the time to review us :)
I like they’re powder and flavors. I just wish I could order only the powder and flavoring. Also wish I could order a much larger container of their powder like every other company I’ve bought from

Hi Kiandra, Thanks so much for your review 🌟
Karina is wonderful and helped me with my SO's lost pacakage issue smoothly and efficiently. My experience with Gainful has been great, have been losing weight and feeling awesome! Once I get to my goal weight, I plan on switching formulas to get buff(er). The pre workout mix gave me a bit of a headache at first but I adjusted the scoop size like the packaging said and it's much better. I would definitely recommend this product and have already done so!
