Mass Gainer vs. Whey Protein: What is the Difference?

Finding the right protein powder can be daunting, especially when numerous are available in the market. Mass gainer and whey protein are among the most common supplements. Both are typically made from milk protein but serve different purposes and goals.

This article will walk you through the basics and highlight the difference between mass gainer and whey protein to help you make the correct choice.

What is Whey Protein?

Whey protein is a protein mixture acquired from milk in cheese production. Milk comprises two types of protein: whey (20%) and casein (80%). Whey is fast-absorbing and among the richest protein sources.

Whey protein proves to be beneficial for health in several ways. It facilitates protein and BCAA (Branched-Chain Amino Acids) intake. While the human body produces a part of amino acids, you must gather the rest from the food you consume. The amino acids you derive from external food sources are known as essential amino acids. Whey protein consists of nine essential amino acids and is rich in BCAAs, like leucine.

Mass gainer is higher in calories and is the preferred option for those with a fast metabolism. If your objective is to increase your overall body mass and add both muscle and some body fat, it can provide the required calories and nutrients you need to achieve these goals.

Mass gainers are available in different types depending on protein to carbs ratio and the number of calories present in them. An ideal mass gainer should have a 1:3 ratio of protein and carbs, respectively. Here is an overview of its general nutrition profile.
