“I’ve been on a fitness journey for a little over 100 days. I got to a point that I felt everything plateau. Once I got my protein from Gainful I started seeing results again. I love it.”

kristen h, 28 | 7.14.23

“I have been incorporating Gainful into my daily routine and loving the results! The flavor boosts are a fun way to enhance the flavor - while avoiding the unnecessary additives found in most protein powders.

    So nice to be able to switch up the flavor day after day. Makes the morning protein shakes not so monotonous.

    I have digestive issues, and this is the first protein that does not give me any bloating or pain when I take it. Would recommend to anybody.

    Jossy M

    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!
