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.

Gentle on the Stomach

Isopure Zero Carb Protein Shake is excellent for sensitive stomachs! I have stomach ulcer and usually struggle with protein powders, but this one is very easy to digest. I've tried many well-known brands, and this is the only protein powder that truly works for me. The only downside is it has very little taste, but its gentle and qualitative formula makes it worth it.
