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.

Would have it again

[This review was collected as part of a promotion.] It’s not a back product at all. I kinda wish it had a flavor but it certainly does the job. It mixed very well with cold water. I had some of my family try it with me and everyone’s opinion was different, but not too bad.

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

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.

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 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.

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.

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

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.
