I love the Gainful Protein Powder with individual flavor packets. The taste is great, I love changing the flavor, & I love the clean ingredients. I feel better not drinking a bunch of artificial flavoring all the time. Best switch I made.

      I’ve tried multiple protein powders on the market and find them to be too chalky and too sweet for my taste. This is a game changer! Light, airy, smooth - PERFECT!
