Mass gainers are specifically designed to help individuals get into a calorie surplus and bulk up, with the assistance of proteins, amino acids, and other nutrients for example. These mass gainers are considered beneficial as they are made with micellar casein, whey protein isolate, whey protein concentrate, vitamins, minerals, and maltodextrin as the primary carbohydrate source. Bodybuilders tend to use their off-seasons to bulk up and increase their muscle mass, allowing them to add size and mass to their frames, before they begin cutting and dieting down a few months later. In order to build mass however, you not only need copious amounts of protein, amino acids, and other nutrients, but you also need to be in a calorie surplus, and the bigger you are, the more calories you need, meaning the more food you would ordinarily need to eat. Mass gainers, provide hundreds, if not thousands, of calories per serving, along with more than enough proteins, amino acids, and other nutrients. They basically function as anabolic meals high in calories, making life that much easier for people trying to bulk up. On top of that, mass gainers can also be useful for people who may simply be struggling to consume enough calories each day. The primary use of mass gainers is to help people to bulk up and add muscle mass to their physiques, and they do this by providing large concentrations of proteins, healthy fats, amino acids, vitamins, minerals, and calories, with every serving. The more muscle you have, the more protein and calories you need per serving, which is where mass gainers come into the mix, providing more than enough of everything that is required to initiate protein synthesis and keep the body in a constant anabolic state.
