The Protein Powder Guide

Whey protein is a mixture of proteins isolated from whey, which is the liquid part of milk separated during cheese production.

Milk contains two main types of protein: 

  1. Casein (80%) 
  2. Whey (20%)

Whey is found in the watery portion of milk. When cheese is produced, the fatty parts of the milk coagulate and the whey is separated as a by-product.

Whenever you open a yoghurt container and see liquid floating on top — that is the whey. 

Whey can be vital for athletes, gym enthusiasts as well as people aiming to lose weight. Additionally, it is also consumed by people who lack protein in their diet.

Whey is generally well tolerated, however people who suffer from lactose intolerance need to be conscious of their individual gut tolerances – and some people may even be allergic to it.

It is also particularly high in important branched-chain amino acids (BCAAs) such as leucine, which studies have shown to be the most anabolic amino acid. 

Whey protein is said to be particularly effective at stimulating growth in human beings. In fact, human breast milk is composed of 60% whey, whereas cow’s milk carries only 20%.

There are several popular types of whey protein. Their main difference is in the way they have been processed.

Whey Protein Concentrate: 

  • +/- 70–80% protein
  • Contains lactose (milk sugar) 
  • Contains fat 

Whey protein concentrate is said to have the best flavour from a consumption standpoint. 

Whey Protein Isolate: 

  • +/- 90% protein
  • Contains less lactose and fat 
  • Does lack some beneficial nutrients found in whey protein concentrate.

Whey Protein Hydrolysate: 

  • A subset of whey protein isolate
  • Pre-digested so that it gets absorbed faster
  • Greater spike in insulin levels when compared with whey isolate


Just like whey protein, casein protein provides all the essential amino acids (EAA’s) your body needs.

After you consume casein, your body’s absorption of amino acids and protein synthesis will peak after 3-4 hours.

Casein protein doesn’t boost your amino acid levels as high or as quickly as whey protein does. It does, however slow the speed at which proteins are broken down in your body. This protects your muscle mass and will make you feel fuller for longer – a great weapon for late-night cravings!

Taking whey protein is a great way to increase your protein intake, which could have major benefits for weight loss. If you’re trying to lose weight, a whey protein supplement can help you both lose weight and hold on to your hard-earned muscle.

More than just muscle, strength and staying lean, whey protein may provide numerous other health benefits.

This includes:

  • Lowering blood pressure
  • Lowering blood sugar 
  • Reducing symptoms of stress and depression (which is imperative with our modern lifestyles)

Ensuring that you get all the beneficial amino acids, we at Evolve Nutrition have used 3 types of protein, each with their own absorption rates and amino acid profile. 

Each serving provides 23g of our meticulously developed whey protein concentrate, hydrolysate and isolate ratio blend, developed to maximise protein levels, along with a reduced carbohydrate and fat content.

This precise formulation ensures an optimal muscle development, lean mass support and recovery, to get your post-workout recovery on track, to fuel your lean mass retention at breakfast or snack times and to act as the ultimate low calorie, muscle protective snack.
