Good, Clean product!

[This review was collected as part of a promotion.] Isopure Zero Carb and Vitamins GF Unflavored protein powder was a pretty big win for me. The product is versatile and offers many benefits. I did notice a slight taste in some drinks but can’t put my finger on what the taste is however in a smoothie/baked goods I didn’t really taste it. It mixed well in my protein shake and overnight oats, have yet to try it in coffee. My container was only filled about halfway, maybe a little less and for the price it kind of sucks you don’t get more. But overall very good product so far, no chalky taste and a good, clean option for those looking to add extra protein in their diet.

Great to mix in meals or drinks

[This review was collected as part of a promotion.] I added a scoop of this protein mix to my coffee. It didn't leave clumps so That was nice. I love that each scoop has 25g of protein and zero carb which is great. It is unflavored and has no taste at all so it's great for adding it to your meals or even blending it in smoothies .

Filling and good!

[This review was collected as part of a promotion.] I have been adding this to my coffee in the mornings. It truly is tasteless and does not affect the flavor of what you put it in. It is kind of thick and powdery and takes a while to stir in, but once you get it mixed in well enough, it’s good. It also makes me full so I don’t overeat. I would definitely consider purchasing again.

Great product

[This review was collected as part of a promotion.] Isopure Zero Carb protein powder is a game-changer if you're serious about upping your protein intake without the extra baggage. It's basically pure protein isolate, so you're getting a super clean source with next to no carbs or fat. The taste is surprisingly good for a protein powder that's so stripped down – it mixes easily and doesn't have that chalky texture some others do. It's not trying to be a dessert, which I appreciate. It’s more about delivering quality protein, and it nails that. Whether you're cutting calories, trying to hit specific macros, or just want a no-nonsense protein boost, Isopure Zero Carb is a solid choice.

Good for extra protein

[This review was collected as part of a promotion.] The Isopure unflavored protein mix, mixes well into anything. There is a little bit of a protein after taste, which is normal for most protein products. It’s a great way to add protein into anything you are making since it is unflavored. It has 25 g of protein, zero sugar, and zero carbs. Would recommend definitely for children who may not eat enough protein, as a mix in.

Versatile Use

[This review was collected as part of a promotion.] I have been adding this protein powder to Kefir drinks and smoothies at home. This powder doesn’t affect the taste of anything I add it to. Mixes very well with no clumping issues with or without a blender. I like that it is flavorless so that it can be used in a versatile way with drinks and recipes for cooking like as a batter for fried chicken or with baking. This allows for the most value and use. I like all the nutrients with vitamins that are also found in this protein powder as well. I appreciate the big container it comes in, as I will be recycling/re-purposing the container for storage.

Does the job!

[This review was collected as part of a promotion.] I’ve never tried an unflavored protein powder so it was unique to add it to my coffee or smoothie and expect no taste. I will say it’s unflavored but still has that protein after taste. Super easy to mix in! Love that it has zero carbs and vitamins so overall, it’s a great product.

So far so good protein powder

[This review was collected as part of a promotion.] My husband has been using it for more than 6 months. So far he likes the product. Good source of isolate proteins for people who are either trying to gain muscle or lose weight. It has no flavor and zero sugar which can be replenished by adding sugar or syrup if you like that way. My husband adds berries for sweetness and peanut butter for taste. You can mix it with water, milk, yogurt, cereal or anything you like. Will but it again and will recommend family and friends.

Zero taste

[This review was collected as part of a promotion.] I’ve been a big fan of isopure protein powders. I love to mix them into my coffee and my newest obsession is to put them into my ice cream using the ninja creami. I like how it has no taste but I know I am getting the protein goals I need.
