1 serving provides 44% of your daily value of protein. Protein is important for proper muscle repair post workout (with adequate protein, recovery times are faster and that weird post workout muscle soreness goes away much quicker).
I admit, I used to be one of those cynical individuals who looked on at others who drank powdered drinks after a workout and thought "hey, you worked out so hard, why are you loading your calories back in?" However, a single serving of this powder only contains 140 calories (which is still less calories than most individuals burn in an hour workout), so you are still operating at a caloric deficient while leveraging the protein for muscle repair. It is important to have a light post workout snack to prevent your body from going into starvation mode (starvation mode is when your metabolism drops really low and your body winds up hoarding fat).
The protein powder also comes in chocolate flavor as well. 22 Days also offer protein and energy bars. I will be trying them soon!
