Most protein powders have a chalky taste but this one didn't. It was delicious in water, added to my yogurt, or with almond milk. I am very particular with protein powders and this one seems to be one of the cleanest and purest ones out there. I highly recommend this product.

this is the BEST casein protein, especially for baking. Hands down, other brands do not compare. this is a staple for my pantry and I use it frequently when making protein muffins or shakes. 10/10
