I appreciate the concept that Gainful has introduced. It’s a unique concept and it works. Taking the quiz about lifestyle and intentions in a protein powder are helpful. In my blend, I appreciate the ease at which the powder can be mixed. Easy on stomach and not clumpy. I haven’t used the product long enough to tell if it does what I’m seeking, yet in general day to day, I’m very satisfied with my blend.

Honestly I had tried protein bars and other shakes before, but gainful not only tastes great but makes me feel like im seeing results after my workouts. The delivery and service is fast and really good. I appreciate everything gainful is

Best protein powder ever. Though I was missing a blender bottle I ordered. They were right in top of it with a refund and they sent me another right away.

I stumbled on this protein powder just by accident. Clicked on a Facebook Ad and there it was. So I figured hey let me give it a try. OMG I am so thankful I did. I am VERY picky with my protein powders, and his one is DELICIOUS! Add a couple of their flavor boosts and you have a different shake everyday. Keeps me full and the energy I have is amazing! Absolutely the best protein powder out there!

I love this powder many ways...in my yogurt. Coffee, shaker cup or a smoothie it blends well is customized to not have the ingredients that bother me and I can choose to use a flavor or not... I love it!

My favorite thing about Gainful is the flavor boosters allow you to choose a different variety each day as opposed to having the same flavor over and over.

I found gainful maybe 2 years ago and have never found an overall protein company that I like better. I was worried when switching to a vegan diet last year that my protein levels would be hard to maintain, but Gainful made it super easy to adjust my formula to accommodate my new eating habits! My plant-based Gainful blend beats all the other vegan protein powders I have tried! Plus, their customer service is unbeatable!
