Whey Protein
Type: Macronutrient
Whey protein is derived from cow's milk, and is considered a complete protein as it provides all 9 essential amino acids, including branched-chain amino acids (BCAAs). Whey protein is essential to support muscle growth, improve muscle strength and promote post-training recovery. There are three main types of whey proteins which vary in their contents of protein, carbohydrates and fat, as well as the absorption rate:
1. Whey concentrate
Contains about 70-80% protein, some lactose and fat
2. Whey isolate
Contains about 90% protein, less lactose and fat. Usually it is quicker to digest than whey concentrate and suitable for individuals who are lactose-intolerant due to its low lactose content
3. Whey hydrolysate
Pre-digested therefore provides quickest absorption.
Whey protein is popular among individuals who are looking at increasing muscle mass and strength. Additionally, as it can be rapidly digested and absorbed by body, it is an ideal supplement for post-workout or training when muscles are primed for nutrient uptake, repair and growth.
