Yes. You may have heard that cooking or heating proteins denature them, which gives the impression that they might be unusable after heat exposure. However, just like meats or eggs, they don’t lose nutritional value after those proteins have changed. They do become slightly more difficult for your body to digest, so it isn’t the best idea to only cook your protein powder. Instead, regularly mixing up your method of consumptions o that you consume protein powder both cooked and uncooked — whether that’s through a smoothie or shake, oatmeal, pasta sauce, dressing, or something else entirely — will help your body to best process the proteins.
