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.

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.

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.

So far so good protein powder

[This review was collected as part of a promotion.] My husband has been using it for more than 6 months. So far he likes the product. Good source of isolate proteins for people who are either trying to gain muscle or lose weight. It has no flavor and zero sugar which can be replenished by adding sugar or syrup if you like that way. My husband adds berries for sweetness and peanut butter for taste. You can mix it with water, milk, yogurt, cereal or anything you like. Will but it again and will recommend family and friends.

Healthy protein with clean ingredients !

[This review was collected as part of a promotion.] Isopure protein powder is one of the best protein powders I have tried so far with zero carb, zero sugar, gluten and lactose free. It is made with clean ingredients and provides 25g of 100% whey protein per serving. It is unflavored and can easily be mixed in coffee, smoothies, yogurt or any baked goods with no after taste. Definitely recommend this if you are trying to build muscle, maintain healthy weight and meet your daily protein requirement.

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.

Should try

[This review was collected as part of a promotion.] This one doesn't change the taste of my drinks at all. I like how simple the packaging it is. It is easy for mixing, but it takes a little bit longer mixing with cold drinks. If its price is affordable, I think it's valuable.

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!

Zero taste

[This review was collected as part of a promotion.] I’ve been a big fan of isopure protein powders. I love to mix them into my coffee and my newest obsession is to put them into my ice cream using the ninja creami. I like how it has no taste but I know I am getting the protein goals I need.

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.
