Z Natural Foods Ultra Whey Protein Isolate Powder - Pure, Unflavored, Unsweetened Whey Protein Powder - Flavorless Whey Isolate with Vital Proteins for Fitness, Sports Nutrition, Immune Support, 1 lb

Great product. Blends well with yogurt. Tasteless and smooth. A perfect way to increase the protein in my breakfast.

The hospital nutritionist recommended whey protein isolate for my post-surgery recovery. She emphasized that I use whey protein isolate as opposed to whey protein concentrate. I eat organic/natural foods so finding a pure, unflavored isolate product was not easy ... I was very happy to discover Z Natural Foods Ultra Whey Protein Isolate. The powder is made in the USA and is Non-GMO, kosher and gluten-free. Bonus: it's packaged in a resealable foil bag rather than a plastic tub. It easily mixed into my milk, yogurt and smoothies and was truly flavorless. Pro Tip: don't even attempt to mix it into hot beverages or foods like oatmeal as it turns into a clumpy mess. I continue to purchase this product to help meet my protein goals. Highly recommended!

This is my go to protein, even git wifey hooked on it. Its whey isolate and unflavored. I still don't recommend drinking it with just straight water, there is no taste but it isn't great. However what it is great for is adding it to coffee, baking with it, cooking with it, adding it to yogurt, pudding etc... The possibilities are endless and such a great way to secretly add protein to your diet. I am on auto order now for this!!

Wonderful product. Dissolves easily with no after taste.

Plain unflavored, unsweetened whey protein: This product is great to scoop into coffee for a protein boost in the morning. I've learned that with a small motorized frother it mixes easily and is undetectable with my cream and sweetener, and I'm kind of finicky about that. It would be noticable for the lightening effect in black coffee, but I don't think it would affect the taste. I kept a scoop from another product that is about 1/4 cup and its perfect. Note: The only time it has failed to mix smoothly was when my coffee was just freshly brewed and especially hot. I set a timer so my coffee usually brews before I wake up and has had about fifteen minutes to sit before I get it, so that's usually not a problem.

Good value! The quality seems good and the flavor is neutral which is what I was looking for to add to keto baked goods. I liked that there aren't a bunch of icky additives. Good sized bag for the price.

I really like this protein powder. I mix it with a serving (3/4 cup) of Vanilla Greek yogurt and it masks the plain whey flavor really good. I use a scoop from another brand of protein powder that equals about 2 servings of this brand (it’s a 49g scoop). Altogether it’s about 60g of protein when combined with the yogurt. I have tried a variety of other things and it mixes well, for example chocolate almond milk. for smoothest results use a blender. Personally I just use a fork to mix it (pro-tip add a little bit of liquid at a time and mix well). Pros - high quality protein, mixes well with a variety of liquids/ yogurt. No artificial stuff. Low calorie. No fillers. Cons - tastes like whey when mixed with other neutral ingredients, what do you expect?

I was intrigued by this product and decided to try it in my morning tea (highly recommend watching attached video for more context). My order arrived on July 21, 2025, and on July 22, 2025, I prepared my first batch using the recommended six leveled tablespoons in a berry smoothie. Typically, my berry smoothies have a vibrant reddish-purple color. However, after adding the protein powder, the color shifted to a milky reddish-purple. Despite this change, the taste remained unaffected, and my smoothie still tasted great. My concern lies in the behavior of the product, as shown in the attached video. While I'm not a scientist or a whey isolate protein expert, the reaction I observed seemed unusual. Consequently, I have stopped using this protein powder after 1 day.
