Isopure Protein Powder, Low Carb Whey Isolate with Vitamin C & Zinc for Immune Support, 25g Protein, Keto Friendly, Chocolate Peanut Butter, 40 Servings, 3 Pounds (Packaging May Vary)

One of the worst protein powders I’ve tried in my life - waste of my money, it doesn’t mix well and the taste is beyond plastic and horrible! I threw mine away - and this has 25g protein only as compared to many other leading ones offering 30g - certainly peanut butter chocolate flavor is the worst one this brand has!

High protein, low-carb & low-calorie. Chocolate peanut butter is the worst flavor in my opinion, I like the toasted coconut and the double Dutch chocolate which are my favorites. This, IsoPure is my go to daily shake in the blender. It’s allowed me to both lose weight and gain lean muscle mass at the same time. That’s the Holy Grail🫡

I’m on a low calorie diet and this protein powder helps me hit my protein macros every day. My husband adds it to his coffee every morning. I drink it hot. I know that sounds weird but I don’t drink coffee so I mix this with warm water in the morning and drink it. It’s not foamy!!! It’s high quality and isn’t gritty. It’s expensive but you’re paying for the quality so it’s worth it to me.

I really like this protein powder. It mixes smoothly and tastes great, not too sweet or artificial. I’ve noticed it keeps me full for a long time and fits perfectly with my low-carb goals. It’s been great for helping me hit my protein target without adding extra sugar. Definitely one of the best protein powders I’ve tried, and I’ll keep buying it even though the it got alittle pricier lately.

I was a customer of isopure for 10+ years. I always recommended them to friends looking for a good protein. Recently it looks like they changed their look but I never saw a mention of change of formula. The powder is gritty, and doesn’t dissolve as well as it used to. The texture is just off now. The calories per serving has changed as well as the size. Flavor is just okay and macros are still good. Just not happy with the sudden change of texture. Edit 8/16/25 I reached out to the company and after sharing my concerns I was informed they’re releasing an updated formula this month to remedy the gritty texture. They were gracious enough to also send me a free tub of this updated formula. I will continue to be a fan of Isopure and recommend it to anyone looking for quality protein supplement.

Solid mix, but the taste disappoints.
