Whey Protein
Whey protein derives from milk, when the fat and carbohydrates are extracted to leave the pure protein found in milk, called whey protein. Trained athletes need to consume roughly 1g of protein per lb of bodyweight a day to actively recovery from intense exercise. Whey protein has the highest bioavailability of any protein substance on earth with a score of around 110 (egg being the closest food with a BV of 100). Whey protein is the bedrock of an effective supplement regime.

Whey protein is so effective at building muscle because it has the highest concentration of muscle building amino acids such as BCAAs. It also sparks the biggest and quickest response in muscle building (known as protein synthesis) when it is digested.

Whey powders often use a mixture of whey proteins as they digest at slightly different times and cost different amounts. The three main types of whey protein are:

Whey protein isolate
These are the purest form of whey protein available; they are above 90-95% pure protein by weight and very low in fat, carbohydrate and lactose. Isolates are digested very quickly by the body and are perfect post workout as well as any time of the day.

Whey protein concentrate
These are anywhere from 30% - 90% whey protein by weight. Whey protein concentrate used in supplements usually hits about 80-85%. Whey protein concentrate contains slightly more fat and carbohydrate that whey isolate, but are still incredibly pure.

Hydrolysed whey protein
These proteins are partially hydrolysed and pre digested in a laboratory and therefore they enter the body quicker than any other form. These are again more expensive than usual whey protein and are perfect post workout due to the fact they are absorbed so quickly.

A great way to take whey protein is first thing in the morning and again post workout. These two times of the day are when your body most needs the muscle building power of whey protein with a fast release of amino acids. If you require more protein you can add another 1 or 2 servings of whey protein throughout the day.
