Mass gainers typically combine protein with carbs and fats, making them ideal for those struggling to eat enough whole foods. Look for options with at least 500 calories per serving and minimal added sugars. Casein protein is another good choice if you want a slower-digesting option, like before bed. Always check the ingredient list for fillers or artificial junk. The right protein powder depends on your diet, budget, and how much you can realistically eat in a day.
