Great protein powder for soup!

[This review was collected as part of a promotion.] I used the Isopure Zero Carb Unflavored Protein Powder in hot soup, and it worked beautifully. I pre-blended it with a bit of cool liquid before adding it to the soup to avoid clumping, and it dissolved completely with no graininess at all. I couldn’t taste it, and it didn’t change the texture of the soup one bit. It’s such an easy way to boost protein without altering flavor. Clean, effective, and exactly what I was looking for!

Great way to add more protein to your diet

[This review was collected as part of a promotion.] I tried mixing this with my morning coffee, and it took a little extra blending to dissolve. The flavor really is unflavored—no weird aftertaste—and it didn’t change the texture of my drink. I did notice a bit of settling at the bottom, but overall it blended well enough and kept me feeling full for hours. A solid option if you want extra protein without added sugars or flavors.

Not bad at all

[This review was collected as part of a promotion.] I like it! I appreciate that it's gluten free. I'm a little hesitant about the unflavored just because typically it still has a flavor and this does still have a flavor but it's extremely mild and doesn't effect the taste of whatever I'm drinking. Love the big scooper. It does make things thicker and frothy. Also always turns whatever I'm drinking white.

Perfect!

[This review was collected as part of a promotion.] I love this stuff for days that I am unable to reach my protein goals. I have added it to yogurt bowls, guacamole, sauces, pasta dishes, and my smoothies. I love that its unflavored. I want to see what else I can add it into for upped protein.

Nice protein

[This review was collected as part of a promotion.] Well I feel I need to use this product longer to give a very honest review but until now is positive. I can mix very easy, the packaging is good but will be better if is a bit smaller container. Not feeling bad taste and easy to make combinations with smoothies or at breakfast.

I love it!

[This review was collected as part of a promotion.] This is great! I add it to either my coffee or smoothies and it doesn't have any affect on the taste, which is great for me because usually I think protein tastes so bad. It mixes in well and isn't gritty. I love it!

Zero carb, add to everything!

[This review was collected as part of a promotion.] I added this to my morning iced coffee and I couldn't taste anything! I'm excited to try adding this to many food and drink items. This container should last for awhile too. I like that it's zero carb as well.

Taste is off

[This review was collected as part of a promotion.] This protein powder has a weird taste and aftertaste that I just cannot get past. I tried it with water and milk and the taste was off-putting. However, it does mix well and is not gritty like some protein powders.

Easy way to get extra protein!

[This review was collected as part of a promotion.] I am constantly on the lookout to add more protein to my meals. This ISOpure unflavored protein powder is amazing to add to baked dishes and baked treats! I have added it to ice cream mixes for my ninja creami machine, I have baked brownies with this powder! I may or may not have also sprinkled a little in my last lasagna dish. It’s incredibly smooth and silky, no weird aftertaste no issues with texture. Mixes well, blends well and you don’t even know it’s there but you are blessed with added protein that normally wouldn’t be there. So happy I was able to try this unflavored protein powder by isopure!
