Protein powders are considered an easy and convenient source of getting high-quality protein. There are three common types of protein powders and they are whey, soy, and casein protein. 

Whey is the most common type of protein powder as it is a water-soluble milk protein. It has several advantages because it is a complete protein and contains all nine amino acids the body needs. 

However, soy protein is more popular among vegans even though it has quite an unpleasant taste. Aside from the unpleasant taste, it also doesn’t dissolve well in water.
