This paper examines the theoretical and evidence-based framework for The MSPM System — Molecularly Structured Protein Matrix in conjunction with neuroacoustic stimulation protocols. It delineates the mechanisms through which this technology facilitates the deceleration of biological ageing by optimising nitrogen balance, supporting mitochondrial function, and harmonising the autonomic nervous system. The study highlights two primary axes of intervention: Biochemical Axis: Focuses on increased nitrogen balance and NAD+ support through a molecularly structured protein matrix with enhanced bioavailability. Neurophysiological Axis: Utilises structured auditory neuromodulation to influence autonomic regulation and heart rate variability (HRV). The integration of these components aims to restore functional coherence between cellular metabolism and systemic regulation, providing a scalable model for regenerative health and functional longevity
