Sustained Release Protein Blends

Sustained Release Protein Blends can contain a mixture of numerous different proteins, including Whey Protein Concentrate, Whey Protein Isolate, Egg, Soy, or Micellar Casein. This allows the Protein Blend to provide fast, medium, and slow digesting proteins which means amino acid release is prolonged for hours, but also the individual gets the best aspects of each individual protein type used in the blend.
