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.

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!

Great product!

I've been using Isopure Unflavored protein powder for a couple of years. It dissolves easily into beverages (I add it to my chai) and I like adding it to my smoothies, Greek yogurt and oatmeal as a way to get extra protein. I also love the large package size which means less ordering + less packaging waste!
