Great Protein for Low-Carb Diets
By Ayla on Reviewed in the United States on July 10, 2025
I’ve been using Isopure Zero Carb Whey Isolate Protein Powder (Vanilla flavor) for my keto and PSMF (protein-sparing modified fast) diet, and I’m impressed with it overall! The vanilla flavor is mild and not overpowering, which makes it easy to incorporate into various shakes or recipes. I love that it’s zero-carb, lactose-free, and gluten-free perfect for anyone on a strict low-carb or high-protein diet. The 25g of protein per serving is great for muscle recovery, and it’s packed with vitamins, making it a solid choice for anyone looking to support their fitness goals while keeping carbs to a minimum. It also mixes well and has a smooth texture, which is a huge plus when you’re drinking it daily. The only minor issue I’ve noticed is that towards the end of the shake, the taste becomes slightly salty if you don’t continue stirring or shaking as you drink. It’s not a dealbreaker, but something to be aware of. If you keep mixing it well, though, this isn’t much of a problem. Overall, I’d recommend this protein powder, especially if you’re following a keto or PSMF plan. The protein quality and minimal carbs make it a top choice in my routine!

First bottle was great, second bottle not so much
By Nick on Reviewed in the United States on July 17, 2025
This is the 3rd container of protein I have purchased from Isopure. The first was cookies and cream, then Vanilla Salted Carmel and now cookies and cream again. The cookies and cream was amazing the first time! For some reason when I just got my new bottle it taste like pure salt and I noticed there are no specs of cookie like the first bottle had. Im not sure if they changed the recipe or if I got a bad batch? Usually I would just tough it out but it honestly taste like pure salt! Not sure where to go from here since the first two bottles were great. This product is pricey but its usually very high quality and worth the money. Hopefully we can get this figured out so I can keep using the product!
