Undetectable with no smell!

[This review was collected as part of a promotion.] This is great to add to anything from smoothies to yogurt to pudding to hit my protein goal. Has no flavor so basically undetectable and no smell. Comes in a large container so you gets more bang for your bucks!

Great Addition to Low Carb/Carb Friendly

[This review was collected as part of a promotion.] This whey protein is unflavored and was a SUPER tasty snack mixed into these GF Banana Nut CC Muffins for some extra protein! Texture is a little sticky so def recommend spraying/lining the muffin tin. This seems to be a great addition to breakfast type items like any low carb or carb friendly oatmeal or pancake. Would love to try it mixed into my AM berries & greens smoothie sometime too. There are lots of low carb recipes on the website - 1 scoop has 25g and I used 3/4 c Isopure: 2 eggs in the muffins. It seems to be pretty clean and follows the

Decent protein powder

[This review was collected as part of a promotion.] This protein powder isn’t bad. It’s unflavored so you have to mix it with something. I mixed it with water the first time and it wasn’t great. However I like flavored stuff. The packaging is a big tub like most protein powders. I wish the tub was a bit smaller for storage reasons. Otherwise a decent protein powder.

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.

Doesn’t mix well

Lots of clumping. Doesn’t mix well. To mix in coffee and be able to drink it you’re going to need a blender.

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

Isopure Zero Carb Protein Powder

[This review was collected as part of a promotion.] Isopure is a clean and easy-to-digest protein powder. Each scoop has 25 grams of whey protein and little to no carbs or sugar, which makes it great for people on low-carb or keto diets.

Good!

[This review was collected as part of a promotion.] I like that this product is unflavored and zero carb. It makes it easy to add to smoothies/shakes without changing the flavor, and I don’t really notice any added texture either.
