I've been using this unflavored whey protein powder daily for 2 weeks. I was specifically looking for something without any added extras so I can mix it into smoothies, homemade popsicles, and waffles without it changing the flavor of the food. What I like: • it mixes in pretty easily • it really is unflavored with just the faintest hint of dairy as you'd expect. • Great protein to calorie ratio. perfect for those of us on a GLP1 medication and watching our protein intake! • Minimal ingredients ... whey protein powder and sunflower or soy lecithin (keeps it in powder form) Things to know: • it's not 100% flavorless. No added flavors of course but it does have a faint taste of dairy as expected. • If you mix it with just plain water, it will look milky, not clear. • the scoop was buried. I guess that's to be expected. Shake the bag some and it will rise to the surface. I mostly use this in my iced coffee each morning along with some oat milk. Delicious and easily digestible, I will be repurchasing in the larger container.

This was my 6th protein powder and thank goodness I kept trying because this is the ONE! I had trouble meeting my protein goals after WLS a year ago. I lost a ton of weight very quickly and my overall nutrition was suffering. I tried 5 other protein powders but they were all no good. They were either extremely gritty or had a horrible taste or both! This one is smooth, creamy and doesnt flavor my coffee- I use it daily to make protein-coffee. The 25g of protein that early in the day gives me an energy boost and helps me feel full for hours. I am diabetic so the zero carbs is also a huge deal to me. The only warnings I have are to make sure to mix it in cold water, milk or creamer. I use an 8$ milk frother to mix it before adding it to coffee or any hot liquid.... I learned that the hard way! It makes the protein clump together into a disgusting gelatinous mess when mixed in hot liquid. The protein denaturates and you absolutely DO NOT want to see that. Mixing it completely in a small amount of cold milk fixed that problem. I added a picture of my coffee that shows how well it mixes in, no clumps, no taste, no carbs! There are frequently sales so the price is very doable if you wait for a sale. The refill I am buying today is 40% off so the 1lb bag is just under 20$. That size will last me about a month. Thats worth it for the relief of FINALLY getting a good textured powder that helps me meet my daily goals. I also haven't noticed any stomach issues with this powder. It does have a faint odor but it is VERY faint. I just dont stick my nose in the bag! Once its in the coffee theres no smell at all. Try this powder if you need to increase your protein without increasing your carbs or calories!

I absolutely love ISOPURE protein powder. I have purchased it many times for in the past 8 years, however, since COVID, the prices jacked up that I have not purchased as much. I have just recently, because there I guess was a small sale going on, either with Amazon or Isopure, I'm not sure, but the prices went back up, again. This is easily mixed in coffee, smoothies, granola, oatmeal, or making protein balls for snacks! It is easy on my stomach, but it's always best to check the labels just in case for anyone else. I love the fact that most Isopure protein powders have the vitamins and minerals added, because msot low or zero carb protein powders are lacking! When just mixed as a protein shake with unsweetened almond milk, the consistency is smooth and the taste is great! Some other powders, I have to use a small amount of sweetener, but with Isopure, I don't. I even use the unflavored and sometimes vanilla in low-carb baking, like in protein pancakes. If they would lower the prices again, I would purchase these again on a regular basis!!!!!

I bought this after reading the reviews, I was hesitant because of the price, but it met my needs of no additives, and no sweetners. I like to sweeten things on my own with honey. This is what I found: 1. Reviews about the inability to reseal the package are true. I cut the bag open carefully, it was impossible to reseal from the very first moment. I keep the bag in another ziplock. Surely this could be improved upon. 2. Reveiws about dissolvability were mixed, but I found the product dissolved even in water with a spoon. I generally use it in smoothies, but have used it in yogurt, hot chocolate, and oatmeal. Dissolves perfectly. 3. Reviews about the taste were mixed, but I found the taste mild enough to mix into the above listed foods —± yogurt, hot chocolate, oatmeal, smoothies — with no detectable taste. If you mix the product with plain water to drink (I tried this!) the taste is not pleasant, but other than that, it works well. 4. Reviews about the amount needed, the size of the scoop, etc., I found misleading. The scoop is the standard scoop I find in all protein powders: 1/4 cup. The amount of protein per scoop is 25 grams. Pretty much the same as all the other protein powder products I've used. Makes you wonder about truth in reporting across the industry...you'd think that without the additives there would be more protein per scoop, but...??? Overall, I was pleased with the product and have purchased it again.

Using this to increase protein for my husband. It mixes into coffee and just tastes like you added cream. Mixes very smoothly.

I like the lack of artificial ingredients, however, It’s slow to mix without a blender, even in hot drinks. It does eventually mix, but it takes longer than collagen powder or bone broth powder. I didn’t notice any weird textures but it does slightly affect the flavor of whatever you put it in despite it being flavorless. It’s not bad enough to return but definitely not sure if I’ll buy this again.
