INCREDIBLE products! It’s difficult to find delicious, clean, plant-based protein options in my area. I love that flavors can be switched up with each new drink! The protein is smooth and keeps me satiated until my next meal. I’d also like to add that customer service is amazing!! Very impressed with the integrity of the company and its products!

Hi Johnny, Thanks for leaving a review! We're happy to hear you're enjoying your Gainful ☺
I've never found other protein powder mixes particularly tasty, but everything I've tried at Gainful has been delicious and smooth. I enjoy the subtle flavor of the mixes alone as they are (usually with soy or coconut milk), but sometimes like to play with a flavor boost. I also have a sensitive gut and I'm very pleased this does not upset it. The folks at Gainful are also super friendly and helpful! Very, very happy with my experience.

The flavors are great, but get easily over powered by any beverage, like oat or almond milk, you can taste the almond or oat more than the flavor boosts. They mix great though, no chunks or any grainy texture. I also though that the suggested 8 ounces is very little.

Was a little skeptical at first but after using the products for the first week loads of positive changes! Some weight loss, better sleep, reigning in nutrition just to name a few. Very surprised and ready for more! Strongly recommend!

I have only been using gainful for three weeks but combined with going to the gym 4-5 times a week I do feel satisfied with this product. With the flavor packets, it tastes great so no complaints on that. I do suggest the variety packets. The registered dietitians are super helpful and it’s nice knowing you do have someone you can ask questions with.
