The importance of protein and understanding the role it plays in not only muscle building but muscle recovery, is one that needs to be understood in order to build a fitter and stronger body.

Whey Protein
Whey protein is found in the watery portion of milk and is a mixture of protein isolates. It’s considered a complete protein – it contains all nine essential amino acids, which the body can’t produce. That’s why whey protein shakes are very important and convenient for muscle gain and why they are so popular in fitness circles. Generally, whey protein contains lower levels of fat and carbohydrates, minimising gut distress and helps with weight-loss.

Whey Isolate
Whey isolate, generally speaking, is understood to go through more processing to eliminate reserves of fat, carbohydrates and lactose. Because of this, whey isolate is normally more expensive than regular whey protein. For this reason, whey isolate is known as the cleaner protein option of the three options discussed.

Unlike whey, casein is a slow releasing protein, which can take up to six hours to completely digest and be utilised. Casein will help drip-feed your muscles over several hours, ensuring your body is constantly topped up with protein.
It may not be ideal during the day – after a gym session – when your body desperately needs that protein fix. However, taking Casein later in the evening – the time when your body recovers best – is the most practical way to keep your muscles firing on all cylinders, avoiding ‘starvation mode’ – when your body starts to break down muscle for fuel.
