Whey Protein

Protein provides amino acids, the building blocks of skeletal muscle, other structures, and various compounds in the body such as enzymes and hormones. Protein intake greater than the recommended dietary allowance (RDA) of 0.8 gram/kilogram/day of body weight has been shown to help individuals performing resistance-training exercise maintain protein balance, build muscle mass, and improve body composition (Aragon et al., 2017; Cintineo, Arent, Antonio, & Arent, 2018; Jäger et al., 2017; Morton et al., 2018). Protein sources with a full spectrum of essential amino acids and adequate amounts of leucine (1.7 to 3.5 grams per dose), the primary trigger of muscle protein synthesis, with some sources having higher amounts of leucine than others, should be selected Whey is particularly rich in EAAs (50% by weight), with the highest leucine content, when compared to other animal protein sources. Due to its solubility, whey mixes easily and is digested and absorbed rapidly, rendering it a particularly popular supplement among exercisers and athletes seeking to increase or preserve muscle mass during intense training and/or dieting in preparation for competition.
