Chiropractic Restoration: A Guide to Metabolic Health

Chiropractic restoration for metabolic health can transform your health journey. Learn more about its potential benefits.

Abstract

In this educational post, I guide readers through the core biology of NAD+ (nicotinamide adenine dinucleotide) and why mitochondrial health, inflammation control, and insulin sensitivity sit at the center of shifting trajectories in chronic cardiometabolic and neurodegenerative conditions. Drawing on the latest clinical and translational findings from leading journals, I explain the mechanisms of NAD+ restoration and mitochondrial support, then translate them into practical, coordinated care. Our multidisciplinary team at Injury Medical Clinic PA (also known as Mission Plaza Injury Medical Clinic) in El Paso, Texas, integrates internal medicine oversight under Dr. Maria Guadalupe Cardenas, MD (Board Certified in Internal Medicine; NPI #1164426749; Texas MD License #J2933; more than 40 years of experience as an internist), who serves as Medical Director and Collaborative Physician, with chiropractic and functional medicine strategies that I lead as Dr. Alex Jimenez, DC, APRN, FNP-BC, CFMP, IFMCP, ATN, CCST. This alignment of medical direction, integrative chiropractic care for biomechanical and autonomic optimization, functional medicine protocols, personal injury services, rehabilitation, and patient education supports safer, more personalized non-surgical approaches. Clinical observations from our practice and educational resources at sciatica.clinic and my LinkedIn profile illustrate how these layers work together in real-world settings.

Introduction: Why NAD+ and Mitochondria Matter in Real Clinical Care

I am Dr. Alex Jimenez, DC, APRN, FNP-BC, CFMP, IFMCP, ATN, CCST. In our El Paso clinic, we combine integrative chiropractic care, functional medicine, internal medicine oversight, and rehabilitation for patients who arrive with overlapping cardiometabolic and neurologic burdens. We often see systemic inflammation, insulin resistance, and mitochondrial dysfunction—all tightly linked to cellular energy shortfalls and NAD+ depletion.

When NAD+ falls, the mitochondrial electron transport chain becomes less efficient, ATP production declines, reactive oxygen species rise, and cellular maintenance programs such as DNA repair, proteostasis, and stress resilience begin to falter. The downstream picture can include atherosclerosis, dilated cardiomyopathy or heart failure with preserved ejection fraction, type 2 diabetes, and neurodegenerative decline. Modern research indicates that targeting upstream drivers, including NAD+ restoration, can help shift these trajectories. I will explain the biochemistry in plain language and show how we integrate these insights within a coordinated multidisciplinary framework, under the medical direction of Dr. Maria Guadalupe Cardenas, MD.

Our Multidisciplinary Team: Internal Medicine Oversight Meets Integrative Chiropractic and Functional Medicine

Dr. Maria Guadalupe Cardenas, MD, brings more than four decades of experience in internal medicine. She is Board Certified in Internal Medicine, holds NPI #1164426749 and Texas MD License #J2933, and serves as Medical Director and Collaborative Physician at Injury Medical Clinic PA (Mission Plaza Injury Medical Clinic) in El Paso, Texas. She provides medical direction, risk stratification, diagnostic coordination, imaging oversight, laboratory interpretation, and pharmacotherapeutic considerations when indicated.

I lead the chiropractic and functional medicine arm. Together, we create a continuum common in modern integrative and personal-injury clinics: the physician provides medical direction and safety oversight, while the chiropractor and functional medicine team address neuromusculoskeletal mechanics, autonomic balance, metabolic terrain, and movement-based recovery.

Key elements of the care continuum include:

• Integrative chiropractic care for biomechanical optimization, neuromuscular balance, and autonomic regulation
• Functional medicine protocols for mitochondrial support, metabolic rebalancing, and anti-inflammatory strategies
• Rehabilitation, movement re-education, and pain science
• Personal injury care and case management
• Advanced diagnostics such as cardiometabolic panels, neurocognitive screening, and imaging as indicated
• Patient education through accessible content at sciatica.clinic and professional reflections on LinkedIn

This structure keeps interventions evidence-informed and tailored to each patient’s cardiometabolic and neurologic context.

NAD+ in Plain English: The Universal Toolkit of Cellular Life

Think of your cells as construction sites. Enzymes are the skilled workers—proteins that catalyze reactions. Those enzymes require coenzymes to function. NAD+ is one of biology’s most critical coenzymes. Without it, enzymes idle. With adequate NAD+, enzymes drive the cellular economy of energy production, signaling, and repair.

Key functions of NAD+ include:

• Acting as an electron carrier in oxidative phosphorylation: it accepts electrons as NADH, feeding the electron transport chain that generates ATP
• Serving as a substrate for sirtuins and PARPs, which regulate gene expression, stress responses, and DNA repair
• Maintaining redox homeostasis by balancing oxidation-reduction reactions
• Coordinating metabolic flux across glycolysis, beta-oxidation, and the TCA cycle

When NAD+ levels drop, mitochondrial output collapses, reactive oxygen species increase, and repair programs slow. Many chronic conditions reflect this cellular energetic failure. Understanding these basics helps explain why restoring NAD+ availability can support multiple organ systems simultaneously.

Why the Heart Depends on NAD+: Metabolic Precision in a High-Demand Organ

The heart contracts roughly 100,000 times per day and needs a continuous supply of ATP. Mitochondrial function inside cardiomyocytes is non-negotiable. Disruptions in ATP production first affect diastolic relaxation, then systolic function, and can progress toward heart failure.

NAD+ supports cardiac physiology by:

• Sustaining electron transport chain efficiency for ATP generation
• Modulating sirtuin activity, particularly SIRT3, which deacetylates mitochondrial enzymes, reduces reactive oxygen species, and helps preserve mitochondrial integrity.
• Supporting calcium handling that protects contractility
• Contributing to mitochondrial biogenesis pathways that involve PGC-1α

Translational research has shown that restoring NAD+ can improve mitochondrial function and ameliorate features of heart failure with preserved ejection fraction in preclinical models. Tong et al. (2021) demonstrated that nicotinamide riboside supplementation or activation of NAD+ biosynthesis corrected cardiac NAD+ deficiency, reduced hyperacetylation of key fatty-acid oxidation enzymes, improved mitochondrial respiration, and reversed aspects of the heart-failure phenotype in a mouse model that recapitulates human disease features. Similar work with nicotinamide has linked cardiac NAD+ deficits to diastolic dysfunction and shown improvements in relaxation mechanics and bioenergetics (Abdellatif et al., 2021). These findings do not imply that established heart failure is always fully reversible in humans, but they open possibilities for combined metabolic, mechanical, and rehabilitative strategies under medical supervision.

In our clinic, Dr. Cardenas coordinates cardiac risk assessment, electrocardiography or echocardiography when indicated, and overall safety monitoring. At the same time, chiropractic care addresses thoracic mobility, rib mechanics, and autonomic balance that influence myocardial workload and recovery.

Type 2 Diabetes: A Mitochondrial and NAD+ Problem Disguised as Glucose Dysregulation

Type 2 diabetes is often framed solely as a glucose problem. Mechanistically, it is better understood as a triad of mitochondrial dysfunction, insulin resistance, and inflammation, each intertwined with NAD+ depletion.

NAD+ participates in glucose regulation because:

• Pancreatic beta-cell glucose sensing depends on mitochondrial ATP generation
• Insulin-receptor signaling is modulated by redox status and sirtuin pathways
• Mitochondrial dysfunction elevates reactive oxygen species that damage insulin signaling and promote inflammation

Preclinical data indicate that elevating NAD+ can improve insulin sensitivity and glucose homeostasis in certain models. Human evidence with oral precursors is mixed and context-dependent; some trials in insulin-resistant but non-diabetic adults have not shown consistent glycemic benefits, underscoring the need for individualized assessment. Upstream mitochondrial repair remains a rational target that can complement conventional diabetes management.

Dr. Cardenas oversees laboratory monitoring (fasting glucose, insulin, HbA1c, lipids, inflammatory markers) and coordinates any pharmacologic considerations. Functional medicine strategies stabilize glycemic load, support protein intake for salvage-pathway substrates, and incorporate graded activity. Chiropractic and rehabilitation improve movement efficiency, making exercise prescriptions safer and more sustainable for insulin-resistant patients.

Alzheimer’s Disease and Neurodegeneration: Reframing Around Mitochondrial Dysfunction

The amyloid hypothesis has struggled to explain clinical outcomes fully. A substantial body of research places mitochondrial dysfunction upstream, generating reactive oxygen species, damaging proteins and lipids, and triggering stress responses that secondarily increase amyloid precursor protein processing.

NAD+ supports neuronal survival through:

• SIRT3 activation that strengthens mitochondrial antioxidant defenses and lowers reactive oxygen species
• Improved neuronal bioenergetics and synaptic stability
• Countering neurodegenerative cascades in relevant models

Studies show that NAD+ restoration can protect neurons, improve cognitive measures, and reduce mitochondrial oxidative stress in experimental systems aligned with Alzheimer’s pathophysiology (for example, work on SIRT3-mediated adaptations in neurons). Vascular contributions, neuroinflammation, sleep disruption, and metabolic inflexibility further amplify the problem. Clinical application therefore emphasizes metabolic restoration—including supervised NAD+ support—alongside neuroinflammation control, vascular health, sleep optimization, and cognitive rehabilitation.

Chronic Disease Convergence: Inflammation, Insulin Resistance, Mitochondrial Failure, and NAD+ Depletion

Across cardiometabolic and neurodegenerative disorders, a convergent biology appears:

• Systemic inflammation driven by NF-κB activation, cytokines, and endothelial activation
• Insulin resistance with impaired receptor signaling and lipid-driven metabolic inflexibility
• Mitochondrial dysfunction featuring impaired electron transport, reduced ATP, and elevated reactive oxygen species
• NAD+ depletion from excessive consumption by PARPs (responding to DNA damage) and CD38 (linked to immune activation and aging), plus reduced salvage-pathway flux

When NAD+ sinks, repair capacity declines, proteostasis falters, senescence signals rise, and organ systems fail. The clinical task is to restore NAD+ and mitochondrial resilience, reduce inflammatory load, improve metabolic flexibility, and rebuild structural-functional integrity through chiropractic, rehabilitation, and lifestyle interventions under medical direction.

How We Integrate Care: Dr. Cardenas and Dr. Jimenez in a Coordinated Model

Dr. Cardenas provides medical direction—ensuring safety, guiding diagnostics, and coordinating pharmacotherapy when needed. I lead neuromusculoskeletal care and functional medicine, optimizing biomechanics and metabolism.

Typical clinical flow includes:

• Medical intake and risk stratification by Dr. Cardenas
• Functional medicine mapping of diet, sleep, stress, toxins, microbiome, and mitochondrial status
• Chiropractic assessment of spinal and pelvic mechanics, autonomic balance, and pain modulation
• Rehabilitation focused on movement patterns, stability, breathing mechanics, and graded activity
• Ongoing laboratory monitoring, imaging, and safety oversight
• Patient education, progress coaching, and outcome tracking

This synergy allows NAD+ strategies, when appropriate, to sit alongside conventional treatments, lifestyle protocols, and manual care rather than as isolated interventions.

The Physiology of NAD+: From Biosynthesis to Action

NAD+ is synthesized through several routes. The de novo pathway begins with tryptophan via the kynurenine pathway. The Preiss-Handler pathway starts from nicotinic acid. The salvage pathway recycles nicotinamide and nicotinamide riboside via NAMPT and NRK; NMNAT converts the intermediate nicotinamide mononucleotide to NAD+.

Compartmentalization matters. Cytosolic NAD+/NADH ratios govern glycolysis. Mitochondrial ratios govern oxidative phosphorylation. Nuclear NAD+ regulates PARPs and sirtuins that influence transcription and repair. Consumers include PARP1/2 (activated by DNA breaks), sirtuins (SIRT1–7), and CD38 (an ectoenzyme that can significantly drain available NAD+).

Optimizing levels therefore requires attention to biosynthesis, consumption, and compartment balance. Clinical strategies range from lifestyle changes and precursors to supervised parenteral or subcutaneous administration when indicated and medically appropriate.

Subcutaneous NAD+ and Precursor Approaches: What the Science Shows and Why It Can Matter

Oral precursors face gastrointestinal and first-pass limitations. Emerging pilot data on injectable nicotinamide riboside (subcutaneous or intramuscular) suggest that repeated administration is generally well tolerated in early studies, with exploratory signals of shifts toward greater mitochondrial ATP production relative to glycolytic ATP production, reductions in certain oxidative-stress markers, and self-reported improvements in fatigue and sleep. These findings are hypothesis-generating; larger, controlled trials are needed. Preclinical work consistently shows that elevating NAD+ enhances mitochondrial respiration, reduces oxidative stress via SIRT3-mediated deacetylation, supports insulin sensitivity in models, attenuates inflammation, and confers neuroprotective effects through mitochondrial stabilization.

Key referenced work includes reviews of NAD+ homeostasis (Katsyuba et al., 2020) and disease-specific studies such as Tong et al. (2021) on heart-failure models. Protocols must be medically supervised. Dr. Cardenas oversees dosing considerations, contraindications, drug interactions, and laboratory monitoring. We integrate these approaches into broader programs rather than treating them as standalone solutions.

Integrative Chiropractic Care: Biomechanics, Autonomics, and Mitochondrial Health in Non-Surgical Treatment

Chiropractic care is often viewed as musculoskeletal only. In our clinic, we emphasize how spinal mechanics, joint function, and neuromuscular balance interface with autonomic regulation, microcirculation, and movement economy—all of which influence mitochondrial demand and supply. This positions integrative chiropractic as a core non-surgical modality that complements metabolic and medical strategies.

Mechanisms include:

• Segmental dysfunction can alter autonomic tone, elevating sympathetic drive, increasing catecholamines, and raising metabolic stress
• Dysregulated movement increases energy cost and local ischemia, driving reactive oxygen species
• Pain amplifies systemic inflammatory signaling that worsens insulin resistance

Interventions we use:

• High-velocity, low-amplitude adjustments to restore joint kinematics and reflex arcs, which can reduce nociceptive input and favorably influence autonomic balance
• Soft-tissue release to improve local perfusion and decrease nociceptive drive
• Breathing and rib-mechanics training to optimize diaphragm function and oxygenation
• Neurodynamic mobilization to improve peripheral nerve glide and reduce local metabolic strain

By improving biomechanics and autonomic balance, we reduce energy leakage, lower inflammation, and create a more favorable terrain for NAD+-driven mitochondrial restoration. Patients with high sympathetic tone often maintain higher pain levels and recover more slowly; combining adjustments with parasympathetic activation techniques frequently improves outcomes, as reflected in educational content at sciatica.clinic.

Functional Medicine Layer: Diet, Sleep, Stress, and Environmental Inputs That Shape NAD+

We address the pillars that determine NAD+ status and mitochondrial resilience.

Nutrition supplies protein for tryptophan and salvage substrates, polyphenols that support sirtuin pathways, and healthy fats for mitochondrial membranes while limiting excess omega-6. Stabilizing glycemic load reduces insulin resistance and inflammation.

Deep sleep supports glymphatic clearance, hormonal regulation, and mitochondrial repair; poor sleep increases CD38 expression and inflammatory signaling.

Chronic stress elevates cortisol and catecholamines, increasing oxidative demand and NAD+ consumption via PARPs. Breathwork, vagal toning, and graded exposure help recalibrate the autonomic nervous system.

Environmental toxicants increase oxidative burden and DNA damage, draining NAD+ by activating PARPs. Assessing exposures and supporting with diet, appropriate sweating protocols, and, when indicated, safe binders can help.

Activity promotes mitochondrial biogenesis via AMPK and PGC-1α, yet overtraining without recovery can deplete pools. Graded, periodized plans are prescribed.

Personal Injury Context: Why Metabolic Support Matters in Recovery

Injury creates a metabolic storm: inflammation surges, pain escalates, sleep declines, movement becomes inefficient, and mitochondrial demand rises while supply dips. We combine rapid mechanical restoration through chiropractic care, medical evaluation for complications, functional medicine to stabilize NAD+ and antioxidant defenses, rehabilitation to retrain efficient patterns, and nutrition to support healing substrates. Aligning these layers can accelerate recovery and reduce the risk of chronic pain and post-injury metabolic dysfunction.

Clinical Observations: Insights From Our Practice and Educational Platforms

Patterns observed in practice and shared educationally at sciatica.clinic and on LinkedIn include faster improvement in sciatica, lumbar disc issues, and nerve-root inflammation when systemic metabolic stress decreases and mitochondrial support increases. Patients with autonomic dysregulation often recover more slowly until chiropractic adjustments are paired with parasympathetic techniques. Insulin-resistant patients frequently heal more slowly; when NAD+ support, nutrition rebalancing, and targeted exercise are coordinated under medical oversight, recovery curves can steepen, and pain markers decrease. These are clinical observations that inform individualized care, not guaranteed outcomes.

Safety and Individualization: Medical Direction by Dr. Cardenas

Any advanced intervention, including supervised NAD+ strategies, requires thorough history and interaction review, baseline laboratories (CBC, CMP, fasting glucose/insulin, HbA1c, lipids, CRP, and oxidative-stress markers when available), cardiac evaluation for symptomatic patients, cognitive and neurologic screening when indicated, informed consent, and structured monitoring. Dr. Cardenas ensures alignment with each patient’s risk profile and goals.

How NAD+ Interfaces With Sirtuins: The Repair and Resilience Axis

SIRT1 influences insulin sensitivity, inflammation, and circadian timing. SIRT3, the major mitochondrial deacetylase, decreases reactive oxygen species by activating enzymes such as MnSOD and optimizes respiratory complexes. SIRT6 and SIRT7 contribute to genomic stability, telomere maintenance, and proteostasis. Increasing NAD+ availability fuels these enzymes, shifting cellular programs toward repair, stress resilience, and metabolic efficiency—foundational for longer-term disease modification.

PARPs and CD38: Managing the Drains on NAD+

PARP activation surges with DNA damage and can consume large amounts of NAD+. CD38 is upregulated in inflammatory states and with aging and catabolizes NAD+. Strategies focus on reducing inflammatory burden through diet, sleep, stress management, and microbiome support; limiting toxin exposure; considering lifestyle factors that may downregulate CD38; and using supervised restoration to outpace consumption while root causes are addressed.

Mitochondrial Biogenesis and Quality Control: AMPK, PGC-1α, and Mitophagy

AMPK senses low energy and activates PGC-1α to induce mitochondrial biogenesis. Mitophagy clears damaged mitochondria, preventing the accumulation of reactive oxygen species. NAD+ supports these processes via sirtuin activity. Clinically, we pair support with appropriate exercise dosing, fasting-mimicking approaches where suitable, and sleep optimization to enhance mitochondrial renewal.

Cardiac, Metabolic, and Neurologic Applications in Practice

Cardiac goals include improving diastolic and systolic function through mitochondrial support, reducing myocardial oxidative stress and inflammation, and enhancing endothelial function. Protocol elements under Dr. Cardenas’s oversight may include supervised NAD+ strategies; cofactors such as CoQ10, L-carnitine, taurine, and magnesium; thoracic chiropractic care; breathing training; and graded aerobics.

Metabolic objectives center on reducing hepatic insulin resistance, improving skeletal-muscle glucose uptake, and decreasing systemic inflammation through nutritional periodization, resistance and aerobic training, and movement optimization.

Neurologic goals support neuronal bioenergetics, reduce mitochondrial oxidative stress, and improve synaptic plasticity via NAD+ restoration with emphasis on SIRT3, sleep and vascular optimization, cognitive rehabilitation, and chiropractic care for cervicogenic contributions to dysautonomia and flow dynamics.

Putting It All Together: The Care Pathway in Our Clinic

The pathway moves from comprehensive medical, functional, and biomechanical assessment through Dr. Cardenas’s diagnostics and risk stratification to an integrative plan that includes chiropractic, functional medicine, and rehabilitation. The plan incorporates NAD+ and mitochondrial support where indicated, followed by monitoring, outcome tracking, iterative adjustments, and ongoing patient education through sciatica.clinic and in-visit coaching.

Educational Summary and Takeaways

NAD+ is a keystone coenzyme for cellular energy, repair, and resilience. Mitochondrial dysfunction sits upstream of many chronic diseases. Emerging evidence, particularly preclinical work on NAD+ repletion in heart-failure models and exploratory human data on injectable precursors, supports the rationale for mitochondrial restoration strategies. Integrative chiropractic care improves autonomic balance and movement efficiency, reducing energy waste and inflammation, and synergizes with these approaches. Our multidisciplinary team under Dr. Cardenas’s medical direction supports safe, personalized implementation.

I share this knowledge because thoughtful application—combining medical oversight, chiropractic care, functional medicine, and rehabilitation—helps patients reclaim function. Educational resources continue at sciatica.clinic and on LinkedIn.
