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!

Great Taste but annoyed
By Stephanie Coons on Reviewed in the United States on July 11, 2025
I was looking for a lactose free protein powder and came across this. I added the cookies and creme to my cart at 19.99, proceeded to continue shopping, by the time I went to check out they raised the price to 26.31, frustrating but ok I still wanted to try it. Well I bought it and not a couple hours later, they dropped the price back down. Super frustrating. Then I get the product and it says NOTHING on the bag about being lactose free which is a bit concerning. I decided to try it anyways since it claims it on here. I mixed it with FairLife milk, a scoop of the powder, and some sf pudding mix, and a couple smashed up Oreos. It tastes AMAZING! So taste is a yes but all the confusion makes it hard to be happy with the purchase.
