    Arginine is a semi-essential amino acid crucial for growth, immunity, and nitric oxide synthesis, especially during stress conditions.

  • 2

    Arginine availability describes the accessible amount of arginine for physiological processes, influenced by its metabolism and transport.

  • 3

    Four definitions of arginine availability exist, each with varying methodologies and implications for health and disease interpretation.

  • 4

    The first two definitions are practical for general assessments, while the fourth offers a comprehensive measure using stable isotope tracer methodology.

  • 5

    Understanding arginine availability is essential for linking measurable parameters to biological processes like endothelial dysfunction and insulin secretion.
