Protein is essential for the growth, repair, and maintenance of tissues in the body. Increasing dietary protein intake may benefit athletic performance, health, and longevity.

Whey Protein DIAAS Complex 1.61 leverages the Digestible Indispensable Amino Acid Score (DIAAS) scientific method for measuring protein quality to maximise bioavailability and deliver an unmatched amino acid profile. This allows you to experience faster recovery, increased muscle growth, and improved overall health and performance.

Essential Amino Acids cannot be made by the body and must be obtained through diet. They are essential for many processes including muscle growth and repair.

Branched-chain amino acids (BCAAs) are a group of three essential amino acids: leucine, isoleucine, and valine. They play a role in muscle growth, repair, and energy metabolism.

Zero added sugars. The only sugar present is naturally occurring from the main ingredients.

Very low fat resulting in a lean whey protein powder for better muscle growth, weight management and improved recovery.
