Fatigue is among the most common reasons patients seek medical care — yet medicine has no specialty dedicated to diagnosing, measuring, and restoring the energy patients say they have lost. Human Energy Science was founded to change that.
Developed by Dr. Fenton G. LeBon, MD — a clinical framework for evaluating human energy as an integrated physiological output, with the same rigor medicine applies to blood pressure, glucose, or renal function.
"Human energy cannot be sustainably increased until the biological factors that diminish it have been identified and removed."
The founding principle of Human Energy Philosophy — before asking what to add, ask what must be removed.
Whether energy loss originates in cardiovascular disease, endocrine dysfunction, sleep disorders, chronic pain, inflammation, or aging itself — the clinical philosophy never changes.
Identify and eliminate the biological factors that consume, impair, or waste human energy — sleep disorders, chronic inflammation, pain, deficiencies, and other biological energy drains.
Return the body's natural systems toward healthy function — restoring physiology rather than suppressing symptoms, and replacing what aging, disease, or stress has depleted.
Only after pathology has been removed and physiology restored: individualized, evidence-based strategies for performance, resilience, and healthy longevity.
Optimization is never a substitute for medicine. It builds upon health — the right intervention, for the right patient, at the right time.
Every patient is evaluated across the six physiological domains that together determine the body's capacity to produce, deliver, regulate, recover, conserve, and utilize energy — transforming a complex symptom into a structured diagnostic process.
The human energy refinery — mitochondrial function, nutrition, iron metabolism, and the cellular machinery that converts raw materials into ATP.
Cardiovascular performance, pulmonary gas exchange, oxygen transport, and the microcirculation that carries fuel to every tissue.
The control systems — thyroid, insulin, cortisol, sex hormones, electrolytes, and autonomic balance that govern when and how energy is used.
Sleep architecture, circadian rhythm, tissue repair, and the physiological processes that restore capacity after every demand.
The hidden cost — chronic inflammation, pain, infection, and environmental stressors that continuously drain the body's reserves.
Brain metabolism, neurotransmitter balance, cognition, attention, and motivation — the highest energy consumer in the body.
From the founding philosophy to the clinics that carry its name — every part of the ecosystem is built on the same science, the same sequence, and the same standard.
The scientific foundation of the ecosystem: the biology of human energy, the published research, the pathway science, and the case for human energy as a primary clinical endpoint.

Find a centerHuman Energy Science begins where energy itself begins — at the level of the mitochondria, the coenzymes, and the signaling pathways that govern cellular energy production, repair, and defense.
NAD⁺ is an essential metabolic coenzyme within the cellular refinery, accepting and transferring electrons so oxidative metabolism can proceed efficiently. Tissue NAD⁺ levels appear to decline with age — an active area of investigation in aging biology.
NAD⁺, SIRT1, and AMPK converge on PGC-1α — the master regulator of mitochondrial renewal — driving the creation of new mitochondria and expanding the cell's energy-producing capacity.
The mitophagy pathway: removal of damaged mitochondria through PINK1/Parkin signaling paired with stimulation of new mitochondrial biogenesis — quality control at the cellular level.
The mitochondrial ROS detoxification cascade — how NAD⁺-dependent signaling activates the cell's own antioxidant defenses, protecting lipids, proteins, and mitochondrial DNA from oxidative damage.
Every physician has heard the same sentence: "I have no energy." Patients bring it to cardiologists, endocrinologists, sleep physicians, and psychiatrists alike. Each specialist evaluates the organ system they know best. Few are positioned to ask the broader question underneath the complaint.
The Human Energy Center traces the full arc of Human Energy Science — the philosophy, the biology, the Six Domains, the diagnostic framework, and the vision for a new multidisciplinary model of medicine built around one of the most universal symptoms in clinical practice.

Dr. LeBon developed the Human Energy Center framework across years of clinical observation — beginning with a pattern every physician recognizes: patients whose diseases had been appropriately evaluated and treated, yet whose energy never returned.
The framework he built proposes that this is not the end of the evaluation, but the beginning of the next phase: a systematic, measurable, evidence-based approach to restoring the body's capacity to produce, deliver, regulate, recover, conserve, and utilize energy. That framework now anchors the entire Human Energy ecosystem — from the published science to the nanoNAD+™ therapeutic platform to the clinical centers that carry its name.
Measure the cause. Restore the system. Rebuild human energy.
