if you want something super simple then this is the product for you. I am not necessarily a fan of unflavored protein powders but i can see a use case for it. for example, when you want to make a dish and want to have extra protein without completely altering the flavor of it. also the macros are very good. good amount of protein per serving and not too many calories either. i also like the simple ingredients list

Truly flavorless

[This review was collected as part of a promotion.] I can add this to anything and it doesn’t change the flavoring. It has everything I need and nothing I don’t want. The wider mouth makes it easier to scoop the powder out.

Love!

[This review was collected as part of a promotion.] I used this in a smoothly and it tasted great. It actually doesnt have a taste to it. So, I can enjoy having that extra protein without even knowing it.

Great product, doesn’t change taste

[This review was collected as part of a promotion.] Great powder that can be mixed with anything, I have used it in baking and on my morning coffee, it does not change the flavor and it does not give it a different texture on anything you add it on.

Must Have Protein

[This review was collected as part of a promotion.] Awesome protein! It’s great to have a flavorless protein to add into so many different things without changing the taste of the food item. It makes it so much easier to get protein in.

Good quality and flavorless

[This review was collected as part of a promotion.] I’ve tried other flavorless protein and it always has a taste, this stuff is different. It’s completely tasteless and mixes very well in both drinks and yogurt.

I love it

[This review was collected as part of a promotion.] I enjoy it. You can add it to anything and it does not have a flavor. I added to my drink and my soup. The packaging is perfect and is a good value. Will buy in the future.
