Good for extra protein

[This review was collected as part of a promotion.] The Isopure unflavored protein mix, mixes well into anything. There is a little bit of a protein after taste, which is normal for most protein products. It’s a great way to add protein into anything you are making since it is unflavored. It has 25 g of protein, zero sugar, and zero carbs. Would recommend definitely for children who may not eat enough protein, as a mix in.

Should try

[This review was collected as part of a promotion.] This one doesn't change the taste of my drinks at all. I like how simple the packaging it is. It is easy for mixing, but it takes a little bit longer mixing with cold drinks. If its price is affordable, I think it's valuable.

Clean protein ideal for custom shakes

[This review was collected as part of a promotion.] If you’re looking for a high-quality whey isolate without the extra sugar, carbs, or unnecessary ingredients, this is it. Pros: Truly unflavored: No sweeteners, no artificial taste, no funky aftertaste. It blends well into just about anything—smoothies, oatmeal, coffee, even soups. Zero carbs + loaded with vitamins: Great for low-carb or keto diets. The added micronutrients are a nice bonus. Mixes easily: A few shakes in a bottle or a quick whirl in a blender, and you’re good to go. No clumping. Cons: Unflavored doesn’t mean tasteless: It has a slightly milky, chalky taste when mixed with plain water. Not bad, but not something I’d drink straight without mixing it into something else. Can be pricey: You’re paying for high purity and added vitamins, but if you're just looking for basic protein, there are cheaper options. Bottom line: If you want a clean, versatile protein supplement that won't interfere with flavors in your custom blends, this is one of the best out there. Just don’t expect it to taste like a milkshake on its own.

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!

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.

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.

Nice protein

[This review was collected as part of a promotion.] Well I feel I need to use this product longer to give a very honest review but until now is positive. I can mix very easy, the packaging is good but will be better if is a bit smaller container. Not feeling bad taste and easy to make combinations with smoothies or at breakfast.

Doesnt change the flavor (unflavored)

[This review was collected as part of a promotion.] I started adding this protein to my daily green juice and honestly I love it! It doesn’t change the flavor of my green juice frappe 😂 and adds protein to it which is helpful! Also, my stomach is doing good with this protein :)

Great protein product!

[This review was collected as part of a promotion.] I’ve been using Isopure Unflavored Whey Protein Isolate, and honestly, it’s one of the cleanest and most versatile protein powders I’ve tried. The best part is how neutral it tastes—I can mix it into smoothies, oatmeal, coffee, soups, or even baked goods without it changing the flavor. It is a little chalky but nothing super crazy. Overall, Isopure Unflavored is my go-to protein when I want something clean, effective, and easy to use every day.

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!
