Mass Gainer Protein Supplement Benefits

The benefits of a mass gainer mainly revolve around simply being high-calorie consumption. Knowing who would use this type of supplement will give you a good idea of what it is.

You would want to use this product if:

  • You have trouble adding on mass (high metabolism or ectomorph body type)
  • You need a meal replacement following a workout
  • You are an athlete and need more calories for your training days

Don’t buy this product if:

  • You are overweight and inactive
  • You are already consuming enough whole foods throughout the day
  • You are on a calorie deficit with carbohydrates

You can see that the main purpose of these products is calorie based. They are around 650-1,400 calories per full serving, which is really close to the calories some need for the day.

The main calories come from carbohydrates and then protein, so if you are doing a low carb or keto diet, then you most likely will want to stay clear of this.

A mass gainer supplement can be used as a meal replacement but is not intended to replace all whole foods completely. One meal and possibly a snack would be okay. Never use supplements as a means to replace all whole foods unless medically advised to.

Mass Gainer Protein Key Ingredients

Inside, these products are more than just protein and carbs. Many mass gainers have reinforced vitamins, minerals, and various amino acids on top of what you gain from the provided protein(s).

Creatine, glutamine, and extra BCAAs/EAAs are commonly added. Basically, these are all ingredients that help stimulate muscle growth through a proper diet and training program. A mass gainer is useless if you are not actively training 3-4 days of the week. The mass you gain without training is fat instead of muscle.

Be cautious with making your decision based on protein content. The protein content is registered in lab analysis through how many amino acids are present.

Creatine, glutamine, BCAA, EAA, taurine, and several others spike protein counts high. An example of this is shown with one of the best mass gainer protein supplements listed below.

Any extra ingredients depend on the supplement brand and what they want to add to their product. The overall substance you get from these products is calories to build up your mass and support training taking place.

Final Thoughts: Best Mass Gainer Proteins

Since the desire is for more calories, you can get even more out of the mass gainer protein products by mixing them with whole milk instead of water. Normally, more ounces are needed to make sure the mixture is not too thick. This not only increases the calories, but makes the protein products taste better as well. Many supplement brands will actually also tell you the additional calories gained if you choose to add in whole milk.

You’ve read our guide on the best mass gainer proteins. If you’re looking to add more mass to your body, use one of our top choices to help you meet your weight goals.
