    • Just what I was looking for!
Flavor Name: Unflavored Size: 2.55 Pound
As someone who usually goes for flavored protein powders, I was intrigued to see how this unflavored option would measure up. Here are my thoughts: **Taste:** Since this protein powder is unflavored, there is no distinctive taste to it. It is essentially a blank canvas that allows you to mix it with any beverage or recipe of your choice. While some may find this lack of flavor unappealing, I personally found it versatile and convenient. I could easily incorporate it into my favorite smoothies, oatmeal, or even baked goods without altering the taste too much. **Texture:** The texture of the powder is smooth and fine, making it easy to mix into liquids without any clumps. It dissolves quickly, leaving no gritty residue behind. I appreciated this aspect, as I've had experiences with other protein powders that don't blend well and result in an unpleasant texture. **Versatility:** One of the biggest advantages of this unflavored protein powder is its versatility. I found it to be a great addition to my post-workout routine, as well as a useful ingredient in various recipes. It allowed me to customize my protein intake without being limited to a specific flavor. I could add it to my morning coffee, blend it into a refreshing smoothie, or even mix it into my favorite pancake batter. The possibilities are endless, and it provides a convenient way to boost protein intake in a variety of ways. **Nutritional Profile:** In terms of its nutritional value, this unflavored protein powder did not disappoint. It offers a decent amount of protein per serving, helping to support muscle recovery and growth. Additionally, it is low in calories and carbohydrates, making it suitable for those who are conscious of their macronutrient intake. **Conclusion:** Overall, I found the unflavored protein powder to be a versatile and convenient option for those who prefer to have control over the flavor of their protein shakes and other recipes. While it may not appeal to individuals who enjoy bold flavors, it offers a blank canvas for creativity and customization. Its smooth texture, ease of mixing, and nutritional benefits make it a good choice for anyone looking to incorporate protein into their diet without compromising taste. ... show more

    • Great addition to any recipes!
Flavor Name: Unflavored Size: 2.55 Pound
I love this protein powder. There's no after taste or gritty texture. It blends great in smoothies and other recipes. The protein count per scoop is one of the better ones on the market.

    • Flavorless and works great in smoothies.
Flavor Name: Unflavored Size: 14.32 Ounce (Pack of 1)
I ordered a couple differently unflavored protein powders to try in smoothies. This one is the winner and this is my second container. The powder is soluble in coconut milk so I’m sure others work well, and there’s no weird taste. I had been experiencing hair loss and have noticed that it has slowed. I believe this is partially responsible with the protein content but judge for yourself. I have a sensitive stomach and this is digestible. The scoop is a good serving size. ... show more

    • Might be the best protein powder.
Flavor Name: Unflavored Size: 14.32 Ounce (Pack of 1)
After years of gagging down painfully sweet and fake tasting protein, I think I’ve found it. This is the most bearable protein powder I’ve ever tried. The texture is fine and seems to dissolve perfectly fine into my matcha lattes. It smells and tastes like milk powder so you can easily blend it into milk products. The texture isn’t chalky. ... show more

    • Buy it!
Flavor Name: Unflavored Size: 1 Pound (Pack of 1)
Clean ingredients but there is a taste to it. Of course most protein powders have that and I don't mind it. But for some it may taste nasty. I put it in my morning iced coffee and used a wireless hand held mixer and yes it blended up well. I'm full now 😊 Buy it! You won't regret it!

    • Taste
Flavor Name: Unflavored Size: 14.32 Ounce (Pack of 1)
I’ve been using Isopure Zero Carb Protein and I really like it. It’s an easy way for me to add more protein to my day without adding a lot of extra calories or carbs. One of my favorite things is the taste. I know a lot of people avoid protein shakes because of that strong protein powder taste, but I don’t get that with this one. It tastes good, mixes well, and is very easy to drink. It is a little more expensive than some other protein powders, but for me, it’s worth paying a little extra because I actually enjoy drinking it and it’s easy to add to my daily routine. Definitely worth it! ... show more

    • Good protein, not a great ‘mixer’
Flavor Name: Unflavored Size: 1 Pound (Pack of 1)
No matter what anyone says, it does have a flavor, it doesn’t mix well in just any drink, and it totally affects the consistency of foods. But if you want a source of packed protein, it does the trick.

    • Great source of protein
Flavor Name: Unflavored Size: 2.55 Pound
Best whey protein, and i've tried many. Easy on the gut, and macros are great. Takes a while to get used to the taste, but once yo get a hang it will become your protein of choice
