Isopure Low Carb 100% Pure Whey Isolate Protein Powder, Lactose Free, Gluten Free, With Vitamins, Dutch Chocolate, 25g Protein Per Serving, 1 Lb, 14 Servings (Packaging May Vary)

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!

I really enjoyed this protein powder! The strawberries & cream flavor is delicious and mixes easily without clumping. Being lactose-free and gluten-free makes it gentle on my stomach, and the 25g of protein per serving helps me meet my nutrition goals, while assisting with weight loss. I also appreciate that it includes vitamins for an extra boost. Overall, a high-quality, convenient protein powder that I would definitely purchase again.

This protein powder mixes easily with water or milk and has a smooth, pleasant taste without being overly sweet. I love that it’s zero carb, making it perfect for my low-carb diet. It’s easy on the stomach, and I feel energized after my workouts. Great quality protein for building muscle and recovery!

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 8/16/25I 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.

I’ve been using Isopure Zero Carb Whey Isolate as part of my nutrition plan, and it delivers exactly what it promises. The big highlight is getting high-quality protein with absolutely no carbs, which makes it perfect for anyone on a low-carb or keto lifestyle. It mixes easily, and I appreciate that it doesn’t leave me with that heavy, chalky feeling that some protein powders do.The flavor is decent and gets the job done, but it’s not the most exciting—definitely more functional than indulgent. That said, I like the clean ingredient profile and how versatile it is for shakes or adding into recipes. For pure, no-nonsense protein that supports lean muscle without extra carbs, this is a solid choice.

Isopure’s Dutch Chocolate whey isolate delivers in every respect. Each scoop packs 25 grams of pure protein without carbs or sugar, so it’s ideal for low-carb or keto goals. It’s also lactose- and gluten-free, and includes a full spectrum of vitamins and minerals to support recovery and daily nutrition needs.Mixing is effortless—just shake it in water or your favorite milk alternative and you're good. The texture is silky smooth and the flavor isn’t overly sweet—just enough cocoa richness to enjoy every sip. I’ve used this post-workout and throughout the day, and it supports recovery without bloating or extra calories.Pros:High-dose protein per serving from clean isolateNo carbs, no sugar; lactose- and gluten-freeSmooth consistency and mild chocolate flavorIdeal for everyday use in low-carb or fitness routinesBig tub lasts a long time and is great valueCons:Flavor is subtle—if you want intense sweetness, this might feel mildSome users sensitive to sweeteners may notice a slight aftertasteBottom Line:Reliable, clean, and easy on the system—this is the protein powder that works for serious fitness goals. It’s straightforward, effective, and stays consistent every time. A smart staple that doesn’t compromise taste or clarity.

A bit different from what I’m used to. It’s more like milk powder in its texture [like instant potato’s but finer] (in the container that is) compared to majority of my proteins that are more like flour).Mixes easily, dissolves completely and taste is pretty good. Smell is pretty low compared to other whey proteins I’ve tried. And scoop value for protein quantity is pretty good meaning less fillers.
