Intramuscular Nad⁺ Therapy And Neuroenergetic Symptom Modulation: An Exploratory Retrospective Human Pilot Study, Zachary J. Dickey Do, Kirtan Patel Bs, Randy Aldret Edd, Cscs, Atc, Navneet Sharma Md, Glenn Goodwin Do

Journal for Sports Neuroscience

Abstract

Background: Nicotinamide adenine dinucleotide (NAD⁺) is a central regulator of neuronal energy metabolism, mitochondrial function, and axonal integrity. Following mild traumatic brain injury (mTBI) and repetitive subconcussive exposure, neurons undergo a neurometabolic crisis characterized by impaired oxidative phosphorylation, increased ATP demand, and depletion of intracellular NAD⁺ pools. Pre clinical models demonstrate that NAD⁺ depletion contributes to central energy dysregulation, cognitive dysfunction, and axonal and neuronal degeneration through disruption of NAD⁺-dependent pathways including SIRT1-mediated mitochondrial resilience, PARP1-driven NAD⁺ consumption, and SARM1-associated axonal breakdown. Despite growing preclinical evidence supporting NAD⁺based neuroprotection, human clinical data remains absent.

Methods: A real-world clinical pilot …
