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.

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.

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.

Protein mix!

[This review was collected as part of a promotion.] This product can go in a variety of food and drinks to make the taste great. It mixes well, and the ingredients give you plenty of extra protein. It is very effective, and the packaging keeps it fresh.

Protein

[This review was collected as part of a promotion.] I have tried a few different kinds of protein and this one isn’t my favorite. For something that says no flavor, I still taste it, even when mixing it with my orange juice, as shown. It’s a VERY large scoop of protein as the recommended dose, and it makes my juice very foamy. I’m sure it’s effective and I do like the packaging, but I don’t think this brand is for me.

Great protein product!

[This review was collected as part of a promotion.] I’ve been using Isopure Unflavored Whey Protein Isolate, and honestly, it’s one of the cleanest and most versatile protein powders I’ve tried. The best part is how neutral it tastes—I can mix it into smoothies, oatmeal, coffee, soups, or even baked goods without it changing the flavor. It is a little chalky but nothing super crazy. Overall, Isopure Unflavored is my go-to protein when I want something clean, effective, and easy to use every day.

Mixes well with anything!

[This review was collected as part of a promotion.] I was incentivized by influenster. This product is perfect put into my Shaker bottle with my smoothie mix. I love that it is unflavored, and it mixes well without leaving clumps. I take it in the morning and it tides me over until lunch. Usually I have a snack in between, but don't need it with this.

Zero carb, add to everything!

[This review was collected as part of a promotion.] I added this to my morning iced coffee and I couldn't taste anything! I'm excited to try adding this to many food and drink items. This container should last for awhile too. I like that it's zero carb as well.

Life Changing!!

[This review was collected as part of a promotion.] This is truly a life changing product!!! I’m one of those girls out there who is trying to eat as much protein as possible and sometimes feel like I run out of ideas or get sick of eating the same things over and over to get in extra protein. But this product allows me to add in protein to virtually anything which is a complete game changer for my diet. I love that it is flavorless and has no carbs so I can add it to both savory and sweet things. I haven’t had a problem with any grittiness or weird textures, it just blends in seamlessly to many things! A truly genius product.

Great!

[This review was collected as part of a promotion.] I use isoprotien everyday! This was a bonus to get to try this im always trying to get extra protein in! This dissolves completely I didn’t have an after taste at all I mixed it in flavored water and if I didn’t know I put it in my drink I’d never known! I would definitely purchase again!
