What is Mass Gainers?

So, what exactly are mass gainer? Simply put, they are a calorie-rich supplement that will help you get that extra bit of calorie count you’ll need to shed for muscle building.

Calling a muscle gainer only calorie-rich might be an understatement, as it comes with various levels of highquality protein, carbohydrates, vitamins, fat gain, amino acids, minerals, and a number of other supplements to gain weight.

Surprisingly, muscle gainers are not a modern concept. Bodybuilders, particularly hard gainers have been using protein bars for a long time for bodybuilding. In its early, crude form, muscle gainers were made using lots of fat burners and sugar, and had to be taken in a large serving.

This didn’t exactly result in a healthy caloric intake, so the need for a more standard, easily understandable system was required.

The BV rating, or Biological Value rating, was then introduced to understand mass gainer better, particularly the standard of the protein used in them. The higher the BV rating of your protein isolate, the faster it will be absorbed by your body.

Although there’s no official categorization of whey protein gainer, you can understand the kind of isolated protein and other supplements you are taking from your mass gainer supplement based on this rating.

How to Choose A Mass Gainer? 

Carb-Protein Ratio

The ideal mass gainers should have a 3:1 ratio of carbs and proteins ration. The protein blends should be complex, meaning a mix of slow, medium, and fast absorbing proteins packed into one, whereas carbs get absorbed slowly naturally.

Added Enzymes
