Amino acids, the building blocks of proteins, are crucial for muscle structure and function.  When intact proteins are consumed, these amino acids first need to be liberated by gastro-intestinal digestion - and this costs precious time and energy.  Intact proteins can slow the rate at which the stomach empties and lead to discomfort during physical activity.  NOWð Amino Peptide is unique in being a pre-digested protein, derived from casein, which delivers high quality, bioavailable amino acids.  Amino Peptide's patent-protected enzymatic process generates tiny protein fragments, known as peptides, that are readily absorbed by the intestine.  Because they are rapidly absorbed into the bloodstream without requiring further digestion, these small peptides are available to fuel the muscles during intense exercise.*
