What Is Mass Gainer?
Mass gainers are high-calorie supplements designed to support weight gain and muscle growth by increasing your daily intake of calories, protein and carbohydrates.
Often called weight gainers, they can be particularly useful for people who struggle to eat enough calories through food alone. When combined with progressive resistance training and a calorie surplus, mass gainers provide a convenient way to support muscle growth, recovery and increased body weight.
