Unflavored protein

[This review was collected as part of a promotion.] This really is unflavored. I have added it to smoothies, yogurt, soup, scrambled eggs, and other stuff and it mixes just fine. It makes the texture a little different but it is barely noticeable.

25 g of protein and no carbs!

[This review was collected as part of a promotion.] 25 grams of protein and no carbs! I use isopure in everything from a regular protein shake to baked goods. I wouldn’t be able to hit my protein goal without it.

Ok, not the best

[This review was collected as part of a promotion.] Mixes very well but doesn't taste the best. No texture noticed when sipping it. I'm just personally not a fan of the taste even tho it's “unflavored”.

Absolutely horrendous. It smelled and tasted rotten. I couldn't even choke down a shake with half a serving in it.

Good, Clean product!

[This review was collected as part of a promotion.] Isopure Zero Carb and Vitamins GF Unflavored protein powder was a pretty big win for me. The product is versatile and offers many benefits. I did notice a slight taste in some drinks but can’t put my finger on what the taste is however in a smoothie/baked goods I didn’t really taste it. It mixed well in my protein shake and overnight oats, have yet to try it in coffee. My container was only filled about halfway, maybe a little less and for the price it kind of sucks you don’t get more. But overall very good product so far, no chalky taste and a good, clean option for those looking to add extra protein in their diet.

Zero Carb Protein

[This review was collected as part of a promotion.] ISOPURE® Unflavored Whey Protein Isolate has zero Carbs + Vitamins GF (704G). It is easy to mix with whatever you’re cooking, baking, or blending. They recommend mixing this product with drinks, hummus, soup, baked goods, guacamole, sauce, oatmeal, etc. Hot or cold. It contains 25 grams of 100% pure whey protein isolate per scoop. It is stripped of fat, carbs, fillers, sugars and lactose & has no added colors, flavors or sweeteners. FYI, the scoop is rather large & there is 22 servings per container.

Easy way to get extra protein!

[This review was collected as part of a promotion.] I am constantly on the lookout to add more protein to my meals. This ISOpure unflavored protein powder is amazing to add to baked dishes and baked treats! I have added it to ice cream mixes for my ninja creami machine, I have baked brownies with this powder! I may or may not have also sprinkled a little in my last lasagna dish. It’s incredibly smooth and silky, no weird aftertaste no issues with texture. Mixes well, blends well and you don’t even know it’s there but you are blessed with added protein that normally wouldn’t be there. So happy I was able to try this unflavored protein powder by isopure!

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.

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 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.
