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.

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.

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!

YES TO ISOPURE!

[This review was collected as part of a promotion.] I first tried Isopure many years ago when my personal trainer told me it was the best protein powder in the market. I use to use the chocolate & vanilla one which tastes soooo good. This is my first time using a flavorless one & you can mix it into anything. It is too thick to be stirred with just a spoon you have to use a blender for it or else it will clump up in your drinks. I showed different angles in the picture so you can see that the manufacturer doesn't fill the container up to the top it's half empty when you receive it. I've used it twice and I realized it came half empty. But I still love Isopure but the manufacturer needs to do better and stop ripping people off. Thank you Influenster for letting me be apart of this program ❤️❤️

We follow applicable laws and regulations related to the manufacture and labeling of our products. The products are filled by weight, not volume. We have Standard Operating Procedures that control how the bottle is filled and subsequently weighed to meet our manufacturing specifications. Like flour or powdered sugar, Isopure powder products can settle in the container during shipping or over time. There also needs to be room for scoopers and desiccant packets in the container.

Super Versatile Zero-Carb Protein

[This review was collected as part of a promotion.] This unflavored protein powder is incredibly versatile with 25g of protein per serving. On its own with water, it’s bland but works in a pinch for a quick shake. Mixed into pasta sauce, it added protein without overpowering the flavor (though it slightly changed the texture). Blended into a smoothie, I couldn’t even tell it was there! I love how many ways I can use it—next I’m trying brownies or another dessert. Great for hitting protein goals without carbs, just not my favorite when mixed alone.

Love!!

[This review was collected as part of a promotion.] Very easy to mix. Packaging was easy to open and close! Very effective and easy to drink! Great price point! The mix did not have any flavor but you can easily add a little flavor to make it even better!

Great product

[This review was collected as part of a promotion.] Isopure Zero Carb protein powder is a game-changer if you're serious about upping your protein intake without the extra baggage. It's basically pure protein isolate, so you're getting a super clean source with next to no carbs or fat. The taste is surprisingly good for a protein powder that's so stripped down – it mixes easily and doesn't have that chalky texture some others do. It's not trying to be a dessert, which I appreciate. It’s more about delivering quality protein, and it nails that. Whether you're cutting calories, trying to hit specific macros, or just want a no-nonsense protein boost, Isopure Zero Carb is a solid choice.

Zero Carb Protein Win!

[This review was collected as part of a promotion.] So I am a workout person who happens to consume a lot of protein to meet my needs. I find most protein powders are very sweet and don’t taste too good to me. I’ve purchased from this brand before and I really love their protein powders. The unflavored one was phenomenal as I am able to add it to other foods or drinks. I did notice that some bits of it doesn’t fully dissolve in water and taste like salt which gives me the ick. Otherwise, this works perfect and gives me a bunch of protein for minimal calories! The container is gorgeous with the almost see through white color. I forgot to mention this is ZERO CARB! That’s a plus for me as someone who is mindful of the carbs I intake on a daily basis. I will definitely purchase this as it does fit my need and is a solid product!!

Great!

[This review was collected as part of a promotion.] I use isoprotien everyday! This was a bonus to get to try this im always trying to get extra protein in! This dissolves completely I didn’t have an after taste at all I mixed it in flavored water and if I didn’t know I put it in my drink I’d never known! I would definitely purchase again!

Does the job!

[This review was collected as part of a promotion.] I’ve never tried an unflavored protein powder so it was unique to add it to my coffee or smoothie and expect no taste. I will say it’s unflavored but still has that protein after taste. Super easy to mix in! Love that it has zero carbs and vitamins so overall, it’s a great product.
