Roles of Protein in the Body

The human body contains an estimated 10,000 to 50,000 different proteins.
Proteins carry out a wide range of functions within the body:

  1. Structural (formation of muscle tissue & bone)
  2. Functional (hormone & enzyme control)

 Once digested and metabolised protein is broken down into amino acids which are the bodies “building blocks “. How these amino acids are joined together dictates its use in the body.

Why use quality protein sources?
Your body is being constantly rebuilt, solely from what you eat.
More than 98% of the molecules of your body are replaced every year:

  • During the last month, your skin and mucous membrane have completely rebuilt themselves.
  • During the last three months you got a whole new blood supply.
  • During the last six months almost every molecule in your muscles has been replaced.

Every time you eat garbage protein, it builds right into your structure. Eat GARBAGE proteins and you grow a garbage body.

Essential vs. Non-essential amino acids
The body utilises 22 amino acids to synthesis all the proteins its needs. However, 8 amino acids are called essential as they must be derived from the diet (i.e. the human body can not manufacture them):


Protein from animal sources, such as meat and milk, is called complete, because it contains all of the essential amino acids.
Most vegetable protein is considered incomplete because it lacks one or more of the essential amino acids.

Protein Requirements
Protein requirements are expressed as the amount of protein (g) required per kilogram (kg) of an individual's body weight, per day.
It has been estimated that the protein requirements for sedentary individuals within a healthy population are approximately 0.8g/kg/day. (Usually rounded to 1gm protein per kg of body weight).
Ideally we should get all our nutrition requirements from food. However due to cost, convenience and increased needs this is not always possible.

WPI (Whey Protein Isolate)
Smaller protein molecules than WPC with a faster absorption rate
Typical protein content: 90-96%
Less lactose content – may be more suitable for people who are lactose intolerant
Less calories than WPC

WPC (Whey Protein Concentrate)
Typical protein content: 80+%
Contains 5-7% milk fat, which contain growth factors to  build lean muscle not usually found in WPI
Higher lactose content than WPI
Due to the higher level of lactose and fat, WPC contains more calories than WPI

Dairy-free with typical protein content: 80+%


Hypoallergenic protein with a lighter texture than other protein powders

Soy, Rice and Pea Protein are vegetarian friendly alternatives to Whey Protein.
