Whey protein is produced using a super-chilled ultrafiltration system where the whey proteins are separated from the milk resulting in a pure and high-quality protein powder.

WPI is more refined than Whey Protein Concentrate (WPC) resulting in higher protein content, less carbs, fats and lactose.

WPI contains all 20 amino acids. Amino acids are the building block of protein and the body requires all of them to build muscle. WPI is considered a complete protein source because it contains all 9 essential amino acids that can only be obtained through diet.

WPI is particularly high in Glutamine and the three main muscle building amino acids, Leucine, Isoleucine and valine, more commonly known as Branched-Chain Amino Acids (BCAAs), making WPI a great protein source for lean muscle growth and repair.

WPI has a greater biological value (BV) than any other type of protein on the market. This means that it provides the largest useable amount of BCAAs and other essential amino acids.

By weight WPI is designed to be at least 90% protein with much less fat and lactose when compared to Whey Protein Concentrate (WPC). WPI contains very minimal amounts of lactose which makes it a good protein for those sensitive to dairy.

WPI is an effective aid in weight loss as it is low in carbohydrates and fats and whey protein gives an addition benefit of a feeling of fullness, suppressing the urges to snack.

A standard serve of WPI is 30g and it is most commonly used as post workout protein powder. However, can be taken anytime of the day for as an addition protein source.
