Super clean protein!

[This review was collected as part of a promotion.] Isopure Zero Carb Unflavored Protein is super clean and versatile—25g of protein per scoop with no carbs or added flavors. It mixes well into water, smoothies, coffee, or even recipes without overpowering the taste. Great for low-carb or keto diets. Simple, effective, and reliable. Highly recommend!

Nice tasteless protein drink that works!

[This review was collected as part of a promotion.] This mixes in soo easily with liquids. It is pretty tasteless, but you can feel thickness from it. It’s standard packaging for a protein powder drink. It works in the same way that most protein powders work. If you’re looking for one that mixes with water and doesn’t leave a taste. If suggest this. I prefer a flavored protein drink personally.

Amazing

[This review was collected as part of a promotion.] This is a relatively good protein powder. I like the fact that it's unflavored, so it doesn't change the flavor of your smoothie. It mixes very well. The taste is okay because it has no flavor packaging is good and the effectiveness. I can tell the difference. It brings between my workouts that I gained a little more strength and I believe it's affordable

Good to try.

[This review was collected as part of a promotion.] I have never tried a protein powder drink before so thank you Influenster and Isopure for the chance. I think it's very easy to mix, the taste is not so bad at all and the plus for me is the zero carb.

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!

Good supplement for protein

[This review was collected as part of a promotion.] I use it for breakfast in my oatmeal to add some extra protein. I couldn’t tell it was in there. No grittiness or weird taste that I could tell. I’d recommend it if you want to add some protein into your diet.

Blends fluffy!

[This review was collected as part of a promotion.] I like the quality of the protein. It isn't gritty, but it does blend fluffy since it's purer. That's not my favorite as it makes me gag, but it's the risk of a good protein powder. I like the fact it's multi use - baking, smoothies etc. It does have an animal like taste you can still taste in some drinks but so best for something that would mask that. Good quality though, and if you need the specialty of what it offers I'd recommend.

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.

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.
