Is it better to mix protein with milk or water?

It depends on your goals. Generally, milk is a better choice if you are looking to gain muscle mass, since milk contains protein, carbohydrates and fat. However, if you are looking to lose weight, then water is usually a better choice since it contains no calories. Additionally, milk can cause gastrointestinal discomfort in some people, so if you are prone to digestive issues then it may be wise to stick with water. Ultimately, the best choice depends on your individual goals and preferences.
