Unlike before, protein shakes are nowadays already available in the market in different types. The most common and inexpensive protein shake is the one called whey protein concentrate. You can also have it in soy, casein, rice, hemp protein and egg, depending on your preference. In choosing what type of protein fits you, you have to put into consideration the nature of each type. If you are lactose intolerant, you cannot have casein and whey since it contains protein which comes from dairy products. In choosing the best flavor, always think of your taste buds because you are the best person to tell which one suits you best. If you want to make it a little fruity, you must choose a neutral flavor such as vanilla and yoghurt. You can make your shake more appealing to your eyes as well by adding freshly sliced fruits on top. You can also have chocolate or cinnamon for a richer and stronger flavor.
