“I enjoy the added nutrition/superfood boost instead of just plain ol' protein with flavoring. If you are already accustomed to protein powders, this one will blow you away from a flavor and health perspective. Highly recommended!”

“This is so delicious, it's hard to believe that it is healthy and good for you, but it is. I love that it is plant protein and low in sugar. Like all KOS products, they have taken the time to combine great taste and all the good stuff your body wants and needs.”
