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

Not bad

[This review was collected as part of a promotion.] Not much to comment on here. I received the unflavored so I wasn’t expecting a whole lot. Typically I like somewhat of a flavor as I tend to mix my protein powders in with my morning coffee but does the trick when adding protein to your diet.

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.

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.

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!

Powerfully perfect protein

[This review was collected as part of a promotion.] This is a fantastic protein based product that can easily be incorporated and she just about anything. I’ve tried this inside of smoothies, pancakes, and various baked goods. It kept me fuller for longer. Not to mention this part did not change the texture or a flavor of whatever it was added to.

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.

Gets the job done!

[This review was collected as part of a promotion.] Great protein powder it’s more than enough you get a great amount of it which I love. The texture is consistent with a powder which is very easily dissolvable. The packaging is very clean, simple and the taste is most non existent. Overall I like this protein powder a lot, great product!

Life Changing!!

[This review was collected as part of a promotion.] This is truly a life changing product!!! I’m one of those girls out there who is trying to eat as much protein as possible and sometimes feel like I run out of ideas or get sick of eating the same things over and over to get in extra protein. But this product allows me to add in protein to virtually anything which is a complete game changer for my diet. I love that it is flavorless and has no carbs so I can add it to both savory and sweet things. I haven’t had a problem with any grittiness or weird textures, it just blends in seamlessly to many things! A truly genius product.

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.
