Frequently Asked Questions
What is the primary difference between Gold Standard Whey Protein and Isopure?
The main difference lies in the protein source and purity. Gold Standard Whey Protein uses a blend of whey protein concentrate, isolate, and peptides, while Isopure primarily uses whey protein isolate. Isopure generally has a higher protein content per serving and is virtually free of carbohydrates and fats, making it a leaner option. This makes Isopure a better choice for low carb dieters.
Which protein powder is better for lactose intolerance?
Isopure is generally a better choice for individuals with lactose intolerance. Whey protein isolate, the primary ingredient in Isopure, undergoes more processing to remove lactose, resulting in a purer form of protein. Gold Standard Whey Protein, with its blend including whey concentrate, may contain higher levels of lactose, potentially causing digestive issues for sensitive individuals. Consider this when choosing.
