    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!
