Promix Whey Protein Isolate Powder vs Whey Protein Concentrate: Whats the difference? The Promix grass fed whey isolate chocolate protein powder is derived from milk, but differs when it comes to the amount of protein content, bcaas, manufacturing processes. Whey protein is a mixture of proteins that is left over after milk has been curdled and strained. It is typically about 70-80% protein by weight. Whey isolate protein, on the other hand, is a more purified form of whey protein that has had most of the fat, lactose, and other impurities removed. It is typically 90% or more protein by weight. Due to this extra purification process, Whey Isolate is usually more expensive than regular whey protein. Additionally, some people with lactose intolerance may find whey isolate a better option as it contains less lactose. You can find our highest rated protein powder in our whey isolate protein puffs, and you can find our grass fed whey protein in our protein puff bars. All of our whey isolate is keto protein friendly, gluten free, low carb protein, and stevia free.
