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.

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.

Zero taste

[This review was collected as part of a promotion.] I’ve been a big fan of isopure protein powders. I love to mix them into my coffee and my newest obsession is to put them into my ice cream using the ninja creami. I like how it has no taste but I know I am getting the protein goals I need.

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.

Mixes well with anything!

[This review was collected as part of a promotion.] I was incentivized by influenster. This product is perfect put into my Shaker bottle with my smoothie mix. I love that it is unflavored, and it mixes well without leaving clumps. I take it in the morning and it tides me over until lunch. Usually I have a snack in between, but don't need it with this.

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.

Versatile Use

[This review was collected as part of a promotion.] I have been adding this protein powder to Kefir drinks and smoothies at home. This powder doesn’t affect the taste of anything I add it to. Mixes very well with no clumping issues with or without a blender. I like that it is flavorless so that it can be used in a versatile way with drinks and recipes for cooking like as a batter for fried chicken or with baking. This allows for the most value and use. I like all the nutrients with vitamins that are also found in this protein powder as well. I appreciate the big container it comes in, as I will be recycling/re-purposing the container for storage.

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.

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.
