Good to try.

[This review was collected as part of a promotion.] I have never tried a protein powder drink before so thank you Influenster and Isopure for the chance. I think it's very easy to mix, the taste is not so bad at all and the plus for me is the zero carb.

Doesnt change the flavor (unflavored)

[This review was collected as part of a promotion.] I started adding this protein to my daily green juice and honestly I love it! It doesn’t change the flavor of my green juice frappe 😂 and adds protein to it which is helpful! Also, my stomach is doing good with this protein :)

Unflavored, texture was nice

[This review was collected as part of a promotion.] This is a good protein powder. It is unflavored, so I can’t comment on the taste. The texture is nice as well. I made protein balls with this and may try it in my smoothies! It also comes in a large container so that was a nice surprise.

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.

Undetectable with no smell!

[This review was collected as part of a promotion.] This is great to add to anything from smoothies to yogurt to pudding to hit my protein goal. Has no flavor so basically undetectable and no smell. Comes in a large container so you gets more bang for your bucks!

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.

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.

Clean protein ideal for custom shakes

[This review was collected as part of a promotion.] If you’re looking for a high-quality whey isolate without the extra sugar, carbs, or unnecessary ingredients, this is it. Pros: Truly unflavored: No sweeteners, no artificial taste, no funky aftertaste. It blends well into just about anything—smoothies, oatmeal, coffee, even soups. Zero carbs + loaded with vitamins: Great for low-carb or keto diets. The added micronutrients are a nice bonus. Mixes easily: A few shakes in a bottle or a quick whirl in a blender, and you’re good to go. No clumping. Cons: Unflavored doesn’t mean tasteless: It has a slightly milky, chalky taste when mixed with plain water. Not bad, but not something I’d drink straight without mixing it into something else. Can be pricey: You’re paying for high purity and added vitamins, but if you're just looking for basic protein, there are cheaper options. Bottom line: If you want a clean, versatile protein supplement that won't interfere with flavors in your custom blends, this is one of the best out there. Just don’t expect it to taste like a milkshake on its own.

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!

It's actually tasteless!

[This review was collected as part of a promotion.] Our whole family agreed that this protein powder truly is tasteless! This is a huge plus for us, as we're always trying to find ways to incorporate more protein into our diet. We tried it in a smoothie and added it to a tomato basil pasta sauce. My picky 6-year-old even asked for seconds! We can't wait to try this powder in more ways.
