I am SOO surprised. I am very hypersensitive to protein powder and have always struggled with any shakes or the “protein-packed” snacks; but I can actually stomach this and my husband has added to my food and I didn't even know until he told me!

Clean powder free of additives

I really love this protein supplement. It has a mild flavor and mixes pretty well with cool water. I chose it because I was searching for a "clean" supplement it found this on another website that listed independently tested powders free of contaminants like heavy metals. I also like that there are no additives. You can mix it in with some foods for a boost of protein. It kinda gives the food a cheesy/umami flavor.

Solid

As billed great supplement. Some tips when adding to coffee - mix separate in shaker with only 4-6oz lukewarm H2O. The mix becomes frothy and adds to coffee without clumping. Overall this has been an awesome addition to daily protein intake. Additionally, though I'm lactose intolerant no issues with my stomach. Already bought more
