Why is Optimum Nutrition Serious Mass better than other Mass Gainers?

Carbohydrates are our body's primary energy source when doing strenuous exercise. Many other mass gainers with similar amounts of calories will add more fat. Optimum Nutrition Serious Mass uses fast digesting maltodextrin as the main carbohydrate source which is broken down into glucose and then used as energy. The higher fat alternatives will ultimately slow digestion, often leaving you feeling lethargic.
