Protein Blends: Cycling and blending protein is a secret that bodybuilders have known for a long time. That's because (1) each protein, whether whey or casein, soy or egg, have different amino acid patterns/ratios; (2) some proteins are more digestible than others; (3) proteins are absorbed at different rates; (4) blends containing multiple proteins may be more advantageous than proteins derived from a single source; (5) whey, egg, casein and soy are all very high quality proteins with different taste and functional characteristics.
