Versatility in Protein

I love using unflavored protein and this is even better since it is super clean.

Good quality, tastes bad

[This review was collected as part of a promotion.] High quality protein but not a fan of the taste. Since it’s low cal it seems like the scoop is way too much for a smoothie and it taste awful. It’s definitely not tasteless

25 g of protein and no carbs!

[This review was collected as part of a promotion.] 25 grams of protein and no carbs! I use isopure in everything from a regular protein shake to baked goods. I wouldn’t be able to hit my protein goal without it.

Good!

[This review was collected as part of a promotion.] I like that this product is unflavored and zero carb. It makes it easy to add to smoothies/shakes without changing the flavor, and I don’t really notice any added texture either.

Smooth and no flavor

[This review was collected as part of a promotion.] We loved this protein powder mix that blends well with yogurt or water! It is so smooth and no clumps. I like to blended in with flavored yogurt, and my husband likes it in water after workouts.

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.
