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.

Loved it!

[This review was collected as part of a promotion.] I was really excited to try this protein powder and it didn’t disappoint. I love how I can use it so many different things. I was able to mix it into shakes, add it to yogurt, and even bake with it. I did find that mixing it by hand was more difficult and I had to use a blender to get it all mixed in evenly. But the best part was it didn’t taste like protein powder.

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 :)

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!

Blends fluffy!

[This review was collected as part of a promotion.] I like the quality of the protein. It isn't gritty, but it does blend fluffy since it's purer. That's not my favorite as it makes me gag, but it's the risk of a good protein powder. I like the fact it's multi use - baking, smoothies etc. It does have an animal like taste you can still taste in some drinks but so best for something that would mask that. Good quality though, and if you need the specialty of what it offers I'd recommend.

Add protein to anything!

[This review was collected as part of a promotion.] I received the isopure unflavored protein with vitamins courtesy of influenster in exchange for my honest review. I really like this product! It has good macros and because it is unflavored, I can mix it in with whatever I want. Sometimes I add it to coffee, dips, or sauces. This product is a great way to increase your daily protein intake. I will definitely purchase this product again in the future!

if you want something super simple then this is the product for you. I am not necessarily a fan of unflavored protein powders but i can see a use case for it. for example, when you want to make a dish and want to have extra protein without completely altering the flavor of it. also the macros are very good. good amount of protein per serving and not too many calories either. i also like the simple ingredients list

Seriously no flavor whatsoever

[This review was collected as part of a promotion.] I swapped out my typical plant protein in my morning smoothie to give this a shot. They're not kidding when they say it's unflavored: you taste nothing. It does still have the smell and texture and aftertaste of whey, but there's no overt taste. This may be a great product for cooking or baking, but I can't recommend drinking it on its own. That said, the nutrition profile is excellent. 110 calories for 25 grams of protein and no carbs is incredibly helpful for hitting your macros.

Zero Carb Protein Win!

[This review was collected as part of a promotion.] So I am a workout person who happens to consume a lot of protein to meet my needs. I find most protein powders are very sweet and don’t taste too good to me. I’ve purchased from this brand before and I really love their protein powders. The unflavored one was phenomenal as I am able to add it to other foods or drinks. I did notice that some bits of it doesn’t fully dissolve in water and taste like salt which gives me the ick. Otherwise, this works perfect and gives me a bunch of protein for minimal calories! The container is gorgeous with the almost see through white color. I forgot to mention this is ZERO CARB! That’s a plus for me as someone who is mindful of the carbs I intake on a daily basis. I will definitely purchase this as it does fit my need and is a solid product!!

Love Unflavored - versatile

I love this product. Mix with a small amout of liquid to smooth the lumps and then mix in the total amount of liquid. If the liquid is too hot the whey tightens up into little chunks, tempering the whey helps. I can add my own flavorings or spices or fruit, and sweeteners, if needed. It is a great base with a slightly cooked milk flavor profile. With a strong flabor like chocolate or mango fruit - can't really taste it, with tea or coffee it adds a milky flavor.
