What Are Mass Gainers?

A mass gainer is typically a powdered supplement that you mix with water, milk, or another desired beverage of choice that is packed with macronutrients to give you quality ingredients so you see an increase in strength and size (1). Also known as weight gainers, these supplements are designed for your bulking needs and work to provide fuel for your workouts, for your muscles grow, and to increase recovery for that added benefit to overall gains. With high amounts of protein and carbs, often times these supplements will have digestive enzymes or an added ingredient to aid in digestion so you can properly absorb all these nutrients without feeling sluggish after.

Key Macronutrients Requirements

As said before, mass gainers are packed with high-quality sources of protein, clean carbs, and healthy fats and it is important to know just what these macronutrients will do and how to consume to maximize the effects of a top tier mass gainer.

Protein is essential to aid in muscle growth and recovery and getting adequate amounts each meal will also keep you full to handle any of your weight management goals. Somewhere in the range of 1.6-2.2 kg/day is ideal for you to maximize muscle hypertrophy (5).


For carbs, which will be on the higher end for mass gainers, these will help restore those lost glycogen stores for energy and to see great growth occur as well. Clean carbs will ensure the weight you gain is healthy and the mass you put on is substantial. Healthy fats are imperative to keep your body fueled and while they make up a much smaller percentage in mass gainers, it is important they are there and to not stress over.

Who Would Benefit From Mass Gainers

Those who would benefit from mass gainers are any lifters or bodybuilders who seek to put on some serious mass.
