A fantastic way to hit protein goals!

[This review was collected as part of a promotion.] As a vegetarian, I’m always looking for ways to sneak a little extra protein into my diet. It feels like I’ve tried every protein on the market and well I do love some, I struggle with drinking chunky, chalky, artificial tasting protein shakes. You know the ones. Well, Isopure has entered the chat. This unflavored, find protein powder is perfect to add to smoothies and recipes I like to add 25g of protein per serving! So far, I’ve only tried this in my smoothies, but I’m looking forward to trying some protein, cookies, brownies, and maybe even adding it to a cheesy recipe to see if I can add a little more nutrition to some comfort foods. Overall, this protein is versatile and blends very well. Just make sure you either use a blender, blender bottle, or add it to warmer liquid before trying to put it in anything else

Protein

[This review was collected as part of a promotion.] I have tried a few different kinds of protein and this one isn’t my favorite. For something that says no flavor, I still taste it, even when mixing it with my orange juice, as shown. It’s a VERY large scoop of protein as the recommended dose, and it makes my juice very foamy. I’m sure it’s effective and I do like the packaging, but I don’t think this brand is for me.

Filling and good!

[This review was collected as part of a promotion.] I have been adding this to my coffee in the mornings. It truly is tasteless and does not affect the flavor of what you put it in. It is kind of thick and powdery and takes a while to stir in, but once you get it mixed in well enough, it’s good. It also makes me full so I don’t overeat. I would definitely consider purchasing again.

Loved it!

[This review was collected as part of a promotion.] I was really excited to try this protein powder and it didn’t disappoint. I love how I can use it so many different things. I was able to mix it into shakes, add it to yogurt, and even bake with it. I did find that mixing it by hand was more difficult and I had to use a blender to get it all mixed in evenly. But the best part was it didn’t taste like protein powder.

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.

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!

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.

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.

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

Decent protein powder

[This review was collected as part of a promotion.] This protein powder isn’t bad. It’s unflavored so you have to mix it with something. I mixed it with water the first time and it wasn’t great. However I like flavored stuff. The packaging is a big tub like most protein powders. I wish the tub was a bit smaller for storage reasons. Otherwise a decent protein powder.
