Amazing personalized protein. Protein does not interfere with taste of other ingredients I add to a shake. Also they have a shakable blender that’s portable anywhere and is great. The pre-work out is great not only is it effective it does not give you the jitters.

Thank you for sharing your experience Libni!🙂
I am on a weight loss journey.... In October I weighed in at 255, today I am 215. I use a rowing machine to get my cardio in, I row 3.5 miles in 50 minutes daily. I use weights for strength training and about a month ago I turned to Gainful protein, I take a variety of fresh berries everyday to boost my immune system and the protein to aid in weight loss and fueling my muscles. Together, I make a mean smoothie. I am very pleased with my goals and the results from my regimen to Gain a better holistic me. I am burning some stubborn fat faster now and I attribute this to incorporating Gainful in my daily weight loss journey. The RD that I have reached out to have answered back promptly with sound information. Overall, I am very pleased with many aspects of my new me... I am a younger 61 year old man thanks to discipline

Hi Charles! We're so happy to hear about the amazing results you've achieved! Thank you for sharing your experience 😄
Just started ordering from Gainful but so far it’s been a great experience. No issues at all, fast delivery, and so easy to really customize your orders. You can even change your preferences once you’ve started your subscription.

Hi Jeff, Thanks for your review 😄
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.

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.
