Gets the job done!

[This review was collected as part of a promotion.] Great protein powder it’s more than enough you get a great amount of it which I love. The texture is consistent with a powder which is very easily dissolvable. The packaging is very clean, simple and the taste is most non existent. Overall I like this protein powder a lot, great product!

I love it!

[This review was collected as part of a promotion.] This is great! I add it to either my coffee or smoothies and it doesn't have any affect on the taste, which is great for me because usually I think protein tastes so bad. It mixes in well and isn't gritty. I love it!

Good supplement for protein

[This review was collected as part of a promotion.] I use it for breakfast in my oatmeal to add some extra protein. I couldn’t tell it was in there. No grittiness or weird taste that I could tell. I’d recommend it if you want to add some protein into your diet.

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 đŸ˜‚ and adds protein to it which is helpful! Also, my stomach is doing good with this protein :)

Would have it again

[This review was collected as part of a promotion.] It’s not a back product at all. I kinda wish it had a flavor but it certainly does the job. It mixed very well with cold water. I had some of my family try it with me and everyone’s opinion was different, but not too bad.

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.

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.

Not bad at all

[This review was collected as part of a promotion.] I like it! I appreciate that it's gluten free. I'm a little hesitant about the unflavored just because typically it still has a flavor and this does still have a flavor but it's extremely mild and doesn't effect the taste of whatever I'm drinking. Love the big scooper. It does make things thicker and frothy. Also always turns whatever I'm drinking white.

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.

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!!
