What is Whey Protein?

Whey Protein is essentially the purest form of protein you can consume. Made from the by-product of cheese manufacturing and milk processing industries, Whey protein is easily digestible in the body.

There are three different types of Whey Protein, viz:

Whey Protein - Isolate

This form of Whey Protein is the purest. It contains roughly about to 90-95% lactose-free Protein. It implies that Whey Protein Isolate contains low-fat content.

Whey Protein - Hydrolyzed

Hydrolyzed Whey Protein is the more popular form of whey protein. It is mostly used in making nutritional products used in sports and medicine. Children's formulas are also made using hydrolyzed Whey Protein.

Basically, in this form, the typical long protein chains are no longer present. Instead, small protein chains are chemically synthesized from the longer ones by hydrolysis. They increase the rate of absorption into the bloodstream. It also makes it suitable for people with allergies.

Whey Protein - Concentrate

The protein content of this type of Whey Protein is usually around 25 to 89 percent. The remaining percent consists of moisture, fats, and carbohydrate. Sometimes, minerals are present.

Mass Gainer

Mass Gainers, or Weight Gainers, are a type of protein supplement blended with essential weight gaining components such as fat and carbs. As the name implies, their primary function is to provide enough calories to your body. Calories, of course, help you gain weight.

As a result, they contain a high carbohydrate to protein ratio. The ratio is usually 3 to 1 or sometimes, 2 to 1. This shows that taking mass gainers means you want to focus on gaining weight.

The carbohydrate present in your typical mass gainer is in form of Maltose and Glucose. Most of the popular mass gainers are taken after a workout. The present carbohydrate and fat help gain weight as well as replenish the body's used-up glycogen. The essential lean protein component present in the supplement help enhances the muscle.
