Not bad

[This review was collected as part of a promotion.] Not much to comment on here. I received the unflavored so I wasn’t expecting a whole lot. Typically I like somewhat of a flavor as I tend to mix my protein powders in with my morning coffee but does the trick when adding protein to your diet.

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.

Ok, not the best

[This review was collected as part of a promotion.] Mixes very well but doesn't taste the best. No texture noticed when sipping it. I'm just personally not a fan of the taste even tho it's “unflavored”.

It's ok.

[This review was collected as part of a promotion.] I'm assuming it's effective, as it keeps me more full during the day. There is no flavor. It mixes well with room temperature drinks than add ice after. You definitely get a lot of product.

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.

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.

Unflavored protein

[This review was collected as part of a promotion.] This really is unflavored. I have added it to smoothies, yogurt, soup, scrambled eggs, and other stuff and it mixes just fine. It makes the texture a little different but it is barely noticeable.

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.
