Red Light Therapy and Mitochondrial Health: The Complete Science Guide

Understanding the Mitochondria-Red Light Connection

Mitochondria represent far more than simple cellular powerhouses—they function as sophisticated energy management systems, cellular signaling centers, and key regulators of health, performance, and aging. When mitochondrial function declines, every aspect of health suffers: energy levels plummet, recovery slows, cognitive sharpness dulls, and aging accelerates. Supporting optimal mitochondrial health therefore becomes foundational to comprehensive wellness strategies.

Red light therapy offers a unique, scientifically validated approach to enhancing mitochondrial function. Unlike supplements that must be digested, absorbed, and metabolized, or exercise that creates additional metabolic demands, photobiomodulation directly delivers energy to mitochondria in the form of photons. This light energy stimulates specific enzymes in mitochondrial respiratory chains, enhancing ATP production, reducing oxidative stress, and supporting cellular repair mechanisms—all without drugs, invasive procedures, or systemic side effects.

The mitochondria-photobiomodulation relationship centers on cytochrome c oxidase—a copper-containing enzyme in Complex IV of the electron transport chain. This enzyme serves as the primary photoacceptor for red and near-infrared wavelengths. When photons at 630-850 nanometers strike cytochrome c oxidase, they trigger conformational changes that enhance electron transfer efficiency, improve oxygen utilization, and dissociate inhibitory nitric oxide that can impair mitochondrial respiration under stress conditions.

The implications extend far beyond simple energy production. Mitochondria influence gene expression, regulate cellular calcium signaling, control programmed cell death pathways, and produce signaling molecules that communicate cellular status throughout the body. By enhancing fundamental mitochondrial function, red light therapy creates cascading benefits affecting physical performance, cognitive capacity, immune function, hormonal balance, and cellular aging processes.

Research documenting these effects spans decades, from NASA's original studies on wound healing and tissue maintenance in space to modern clinical trials examining athletic recovery, neurodegenerative conditions, and metabolic health. The consistent finding: appropriate red light exposure measurably improves mitochondrial efficiency, with effects manifesting as reduced fatigue, enhanced recovery, improved resilience to stress, and better long-term cellular health.

Understanding mitochondrial health provides context for evaluating red light therapy's diverse applications. The same cellular energy enhancement that accelerates muscle recovery also supports cognitive function, wound healing, and skin rejuvenation—mitochondria in all tissue types respond to improved energy availability. This unifying mechanism explains why photobiomodulation benefits such varied conditions and applications.

How Red Light Therapy Influences Mitochondrial Function

The relationship between specific light wavelengths and mitochondrial enhancement involves sophisticated molecular biology. Understanding these mechanisms reveals why photobiomodulation produces such diverse therapeutic effects from a single fundamental intervention—improved cellular energy production.

Photobiomodulation: Light as Cellular Energy

Photobiomodulation describes the phenomenon where specific wavelengths of light create biological effects through photochemical rather than thermal mechanisms. Red (630-660nm) and near-infrared (810-850nm) wavelengths penetrate tissue effectively, reaching mitochondria within cells throughout the exposure area. These wavelengths match the absorption spectrum of key mitochondrial chromophores—light-sensitive molecules that convert photon energy into biochemical changes.

The primary photoacceptor is cytochrome c oxidase (also called Complex IV), the terminal enzyme in the mitochondrial electron transport chain. This copper-containing protein complex serves as the final electron acceptor in cellular respiration, transferring electrons to oxygen molecules to complete the energy production cycle. When photons at therapeutic wavelengths strike cytochrome c oxidase, several critical changes occur simultaneously.

First, the light energy causes conformational changes in the enzyme's structure, enhancing its catalytic efficiency. Electron transfer rates increase, oxygen binding improves, and the overall throughput of the electron transport chain accelerates. Second, absorbed photons dissociate nitric oxide (NO) from cytochrome c oxidase. Under normal conditions, small amounts of NO bind to this enzyme, creating mild inhibition. Under stress, inflammation, or hypoxic conditions, excessive NO binding significantly impairs mitochondrial respiration. Photobiomodulation releases this inhibitory NO, restoring normal enzyme activity.

These molecular changes translate directly into improved mitochondrial performance. Cells produce more ATP per oxygen molecule consumed, reducing metabolic waste. The respiratory chain operates more efficiently, minimizing production of damaging reactive oxygen species that occur when electrons "leak" from impaired transport chains. Overall cellular energy status improves, providing resources for repair, maintenance, and optimal function.

Cytochrome c Oxidase Activation and ATP Production

Cytochrome c oxidase occupies a critical position in cellular energy production. As Complex IV of the electron transport chain, it catalyzes the final transfer of electrons to oxygen, creating water while pumping protons across the inner mitochondrial membrane. This proton pumping generates the electrochemical gradient that drives ATP synthase—the enzyme that actually produces ATP molecules.

Red and near-infrared light absorption by cytochrome c oxidase creates measurable increases in enzyme activity. Studies using fluorescent ATP sensors demonstrate 30-50% increases in cellular ATP levels following appropriate photobiomodulation protocols. This substantial energy boost enables cells to better perform all ATP-dependent functions: protein synthesis, active transport across membranes, muscle contraction, nerve signal transmission, and cellular repair processes.

The ATP enhancement proves particularly valuable during conditions of cellular stress. Inflammation, injury, aging, and metabolic dysfunction all impair mitochondrial efficiency, reducing ATP availability precisely when cells need extra energy for recovery and repair. Red light therapy helps restore normal energy production in these compromised cells, supporting healing and functional recovery.

Beyond simply increasing ATP quantity, photobiomodulation improves the efficiency of ATP production. Cells generate more energy per unit of oxygen and nutrients consumed, essentially improving their metabolic "fuel efficiency." This enhanced efficiency reduces oxidative stress from metabolic byproducts while simultaneously increasing energy availability—a win-win for cellular health.

Impact on Mitochondrial Biogenesis and Gene Expression

Mitochondrial biogenesis—the creation of new mitochondria within cells—represents another pathway through which red light therapy supports long-term cellular health. Cells dynamically adjust mitochondrial numbers and function in response to energy demands and cellular signals. Enhanced energy production from existing mitochondria triggers signaling cascades that promote creation of additional mitochondria, increasing overall cellular energy capacity.

Several transcription factors regulate mitochondrial biogenesis, with PGC-1α (peroxisome proliferator-activated receptor gamma coactivator 1-alpha) serving as master regulator. PGC-1α activation increases expression of nuclear genes encoding mitochondrial proteins and promotes replication of mitochondrial DNA. Research indicates that photobiomodulation can stimulate PGC-1α activity, supporting increased mitochondrial mass and function over time with consistent use.

Gene expression changes extend beyond mitochondrial biogenesis. Red light therapy influences expression of genes involved in antioxidant defense (superoxide dismutase, catalase, glutathione peroxidase), cellular stress response (heat shock proteins), inflammation regulation (cytokine signaling), and cellular repair (growth factors and repair enzymes). These widespread gene expression changes help explain photobiomodulation's diverse therapeutic effects stemming from a single intervention.

The mitochondrial DNA itself may benefit from reduced oxidative stress. Mitochondria contain their own circular DNA encoding 13 essential proteins for the electron transport chain. This DNA lacks the protective histones surrounding nuclear DNA and sits adjacent to the electron transport chain where reactive oxygen species are generated, making it particularly vulnerable to oxidative damage. By improving respiratory chain efficiency and reducing ROS production, red light therapy may help preserve mitochondrial DNA integrity, supporting long-term mitochondrial health.

Mitochondrial Function and Cellular Energy Production

Appreciating how red light therapy enhances mitochondrial health requires understanding normal mitochondrial function. These organelles execute complex biochemical processes converting nutrients into usable cellular energy through elegant, multi-step pathways refined over billions of years of evolution.

Cellular Respiration and the Electron Transport Chain

Cellular respiration breaks down glucose, fatty acids, and amino acids through a series of chemical reactions extracting energy stored in molecular bonds. The process begins with glycolysis in the cytoplasm, continues with the citric acid cycle (Krebs cycle) in the mitochondrial matrix, and culminates with the electron transport chain in the inner mitochondrial membrane.

The electron transport chain consists of five protein complexes (Complexes I-V) embedded in the inner mitochondrial membrane. As electrons from NADH and FADH2 (produced by earlier metabolic steps) pass through these complexes, the energy released pumps protons from the mitochondrial matrix into the intermembrane space. This creates an electrochemical gradient—the proton-motive force—that stores energy like a charged battery.

Cytochrome c oxidase (Complex IV) catalyzes the final critical step: transferring electrons to oxygen molecules, reducing them to water. This reaction must occur efficiently to prevent electron backup through the chain, which increases reactive oxygen species production when electrons "leak" and prematurely react with oxygen. Complex IV's efficiency therefore determines not just energy production but also oxidative stress levels.

When the electron transport chain functions optimally, it couples electron flow tightly to ATP production while minimizing ROS generation. Impairments anywhere in the chain—from aging, inflammation, toxins, or insufficient nutrients—reduce efficiency, decrease ATP output, and increase oxidative stress. Red light therapy's enhancement of Complex IV function helps restore optimal chain operation, improving both energy production and metabolic health.

ATP Synthase and the Proton-Motive Force

ATP synthase (Complex V) represents one of nature's most elegant molecular machines. This enzyme spans the inner mitochondrial membrane, functioning as a rotary motor powered by the proton gradient. As protons flow back across the membrane through ATP synthase, the enzyme rotates, catalyzing ATP formation from ADP and inorganic phosphate.

Each complete rotation of ATP synthase produces three ATP molecules. The enzyme operates continuously as long as the proton gradient remains strong and substrates (ADP and phosphate) are available. The stronger the gradient, the more ATP synthase can produce—making the electron transport chain's proton-pumping efficiency critical for ATP availability.

By enhancing Complex IV efficiency, red light therapy strengthens the proton gradient driving ATP synthase. The improved electron transport pumps more protons across the membrane per unit time, creating a more robust electrochemical gradient. This enhanced gradient enables ATP synthase to operate at higher rates, producing more ATP to meet cellular energy demands.

The relationship proves particularly important during high energy demand situations: intense exercise, tissue healing, immune responses, or cognitive activity. These conditions require substantial ATP production, potentially straining mitochondrial capacity. Enhanced mitochondrial efficiency from regular red light therapy helps cells better meet these elevated energy demands without exhausting reserves or producing excessive oxidative stress from metabolic strain.

Mitochondrial Membrane Potential and Cellular Health

The mitochondrial membrane potential (ΔΨm) represents the voltage difference across the inner mitochondrial membrane, typically around -180 millivolts with the matrix negative relative to the intermembrane space. This electrical gradient, combined with the pH gradient from proton accumulation, creates the proton-motive force powering ATP synthesis.

Membrane potential serves as a sensitive indicator of mitochondrial health. Strong, stable membrane potential signals healthy respiratory chain function and adequate ATP production capacity. Declining membrane potential indicates mitochondrial dysfunction—from impaired electron transport, proton leak through damaged membranes, or other mitochondrial pathologies. Severely collapsed membrane potential triggers cellular stress responses and can initiate programmed cell death if restoration fails.

Research demonstrates that photobiomodulation helps maintain or restore healthy membrane potential in stressed cells. By improving electron transport efficiency and reducing oxidative damage to mitochondrial membranes, red light therapy supports the robust membrane potential essential for optimal ATP production and cellular function.

The membrane potential also drives other critical mitochondrial functions beyond ATP synthesis: calcium ion transport for cellular signaling, protein import from cytoplasm into mitochondria, and reactive oxygen species signaling. Supporting optimal membrane potential through photobiomodulation therefore benefits multiple cellular processes simultaneously, contributing to comprehensive cellular health improvements.

Key Benefits of Enhanced Mitochondrial Health

Improved mitochondrial function from red light therapy translates into observable benefits across diverse health domains. Because mitochondria power virtually all cellular activities, enhancing their performance creates system-wide improvements in energy, recovery, cognition, and resilience.

Reduced Oxidative Stress and Inflammation

Reactive oxygen species (ROS) play a paradoxical role in cellular health. At appropriate levels, they serve important signaling functions. Excessive ROS production, however, causes oxidative damage to proteins, lipids, DNA, and cellular structures—a major contributor to aging, chronic disease, and impaired recovery from injury or illness.

Mitochondria represent both major producers and targets of ROS. When electron transport chains function inefficiently, electrons "leak" and prematurely react with oxygen, generating superoxide radicals. These radicals and their derivatives damage mitochondrial membranes, proteins, and DNA, creating a vicious cycle where oxidative damage further impairs mitochondrial function, leading to more ROS production.

Red light therapy breaks this cycle by improving electron transport efficiency. Enhanced cytochrome c oxidase activity reduces electron backup and leakage, lowering ROS generation at the source. Simultaneously, the therapy stimulates expression of antioxidant enzymes—superoxide dismutase, catalase, glutathione peroxidase—that neutralize ROS before they cause damage. The net effect: substantially reduced oxidative stress throughout treated tissues.

The anti-inflammatory effects extend beyond simple ROS reduction. Improved mitochondrial function modulates inflammatory cytokine expression—reducing pro-inflammatory mediators like IL-1β, IL-6, and TNF-α while maintaining or increasing anti-inflammatory factors like IL-10. This balanced immunomodulation helps resolve chronic inflammation without suppressing necessary immune functions, supporting both healing and long-term health.

Enhanced Physical Recovery and Athletic Performance

Athletes and physically active individuals particularly benefit from red light therapy's mitochondrial enhancement. Exercise creates substantial energy demands, depletes ATP stores, generates oxidative stress, and causes microscopic muscle damage requiring repair. Enhanced mitochondrial function accelerates recovery from these metabolic challenges.

Pre-exercise photobiomodulation may improve performance through several mechanisms. Increased baseline ATP availability provides better energy reserves for high-intensity efforts. Enhanced oxygen utilization efficiency improves aerobic capacity. Reduced oxidative stress preconditioning may limit exercise-induced damage. Studies show that athletes using pre-workout red light therapy demonstrate improved strength output, endurance capacity, and delayed fatigue compared to controls.

Post-exercise application accelerates recovery more dramatically. The enhanced ATP production supports rapid muscle repair and glycogen resynthesis. Reduced inflammation and oxidative stress minimize delayed onset muscle soreness (DOMS). Improved circulation delivers nutrients and oxygen while removing metabolic waste products more efficiently. Many athletes report 20-40% reductions in recovery time between intense training sessions with consistent post-workout photobiomodulation.

The benefits extend beyond elite performance. Recreational exercisers experience less soreness, faster recovery, and better training consistency. Older adults maintain better strength and function with enhanced recovery capacity. Anyone with physically demanding work benefits from improved resilience to physical stress and faster tissue repair.

Cognitive Function and Neuroprotection

The brain consumes approximately 20% of the body's total energy despite representing only 2% of body weight. This extraordinary energy demand makes neural tissues particularly sensitive to mitochondrial function. Neurons require constant ATP supplies for neurotransmitter production, action potential propagation, synaptic transmission, and maintenance of ion gradients essential for neural signaling.

Red light therapy, particularly using near-infrared wavelengths that penetrate skull bone, can enhance cerebral mitochondrial function. Improved neuronal ATP availability supports better cognitive performance—enhanced focus, improved memory consolidation, faster information processing, and greater mental endurance. Some users report clearer thinking and reduced mental fatigue within days of beginning consistent protocols.

The neuroprotective effects prove particularly intriguing. Mitochondrial dysfunction contributes significantly to neurodegenerative conditions including Alzheimer's, Parkinson's, and age-related cognitive decline. By supporting neuronal mitochondrial health, photobiomodulation may help preserve cognitive function and potentially slow neurodegenerative progression. While research continues, preliminary studies show promising results for cognitive preservation with regular transcranial photobiomodulation.

Mood and stress resilience also benefit from enhanced neuronal mitochondrial function. The brain regions regulating mood, stress response, and emotional regulation require substantial energy. Improved mitochondrial capacity in these areas supports better stress adaptation, mood stability, and emotional resilience. Users commonly report improved mood and reduced stress impact with consistent red light therapy protocols.

Sleep Quality and Circadian Rhythm Support

The relationship between mitochondrial health and sleep quality operates bidirectionally. Poor sleep impairs mitochondrial function through multiple mechanisms, while mitochondrial dysfunction disrupts sleep through altered energy metabolism and circadian signaling. Red light therapy may help break this negative cycle by supporting both mitochondrial health and proper circadian rhythm regulation.

Morning red light exposure, particularly at 660nm wavelengths visible to the eye, helps entrain circadian rhythms through effects on retinal cells and suprachiasmatic nucleus—the brain's master circadian clock. This morning light exposure supports proper melatonin suppression during waking hours and appropriate melatonin release at night, promoting natural sleep-wake cycles.

Evening near-infrared exposure (which doesn't disrupt melatonin like blue light) may support sleep quality through enhanced mitochondrial ATP production. Better cellular energy status allows more efficient cellular repair and maintenance during sleep, potentially improving sleep quality and reducing nighttime awakenings. Some users report deeper, more restorative sleep with evening red light protocols.

The mitochondrial benefits compound over time—improved sleep supports better mitochondrial function during waking hours, while enhanced mitochondrial health supports higher-quality sleep, creating a positive reinforcement cycle supporting both energy and recovery.

Skin Health Through Dermal Mitochondrial Enhancement

Skin cells—fibroblasts, keratinocytes, melanocytes—all contain mitochondria requiring ATP for their specialized functions. Fibroblasts need substantial energy for collagen and elastin synthesis. Keratinocytes require ATP for their rapid turnover and barrier function maintenance. Enhanced mitochondrial function in these cells translates directly into improved skin health and appearance.

Red light therapy stimulates fibroblast mitochondria, increasing collagen production that reduces fine lines and improves skin firmness. Enhanced keratinocyte energy supports better skin barrier integrity and faster turnover, improving texture and tone. Improved circulation from nitric oxide release delivers more nutrients to skin cells while removing waste products more efficiently.

The anti-aging effects stem partly from reduced oxidative damage to dermal mitochondria. Skin mitochondria face constant oxidative stress from UV exposure, environmental pollutants, and metabolic processes. By enhancing mitochondrial antioxidant defenses and reducing ROS production, red light therapy helps preserve youthful mitochondrial function in skin cells, slowing visible aging processes.

Wound healing acceleration similarly reflects enhanced mitochondrial function in repair processes. Faster ATP production enables more rapid cell migration, proliferation, and extracellular matrix synthesis—all energy-intensive processes essential for efficient wound closure and tissue remodeling.

Integrating Red Light Therapy with Mitochondrial-Supporting Lifestyle Factors

While red light therapy powerfully enhances mitochondrial function, combining photobiomodulation with other mitochondrial-supporting practices creates synergistic effects exceeding any single intervention. A comprehensive approach to mitochondrial health maximizes both immediate benefits and long-term cellular resilience.

Exercise and Movement for Mitochondrial Stimulation

Exercise represents one of the most potent natural stimulators of mitochondrial biogenesis and function. Physical activity creates energy demands that trigger adaptive responses—increased mitochondrial density, improved respiratory chain efficiency, enhanced antioxidant defenses, and better metabolic flexibility. Combined with red light therapy, exercise creates powerful synergistic mitochondrial enhancement.

Aerobic exercise particularly stimulates mitochondrial adaptations. Activities like running, cycling, swimming, or brisk walking performed at moderate intensity for 30-45 minutes trigger signaling cascades activating PGC-1α—the master regulator of mitochondrial biogenesis. Regular aerobic training substantially increases mitochondrial density in trained muscles, improving endurance and metabolic health.

Resistance training also supports mitochondrial health through different pathways. While building muscle mass and strength, resistance exercise creates metabolic stress that promotes mitochondrial adaptations supporting the enhanced energy demands of increased muscle tissue. The combination of aerobic and resistance training provides comprehensive mitochondrial stimulation.

The timing of red light therapy relative to exercise matters. Pre-exercise exposure may prime mitochondria for enhanced performance. Immediate post-exercise application captures the metabolic window when tissues are primed for adaptation and recovery. Both approaches benefit mitochondrial health, with post-exercise timing showing strongest recovery benefits in research.

Nutritional Support for Mitochondrial Function

Mitochondria require specific nutrients for optimal function. Micronutrients serve as cofactors for respiratory chain enzymes, precursors for energy molecule synthesis, and antioxidants protecting against oxidative damage. While red light therapy enhances mitochondrial function through photochemical mechanisms, adequate nutrition provides the raw materials mitochondria need to capitalize on this enhancement.

Critical mitochondrial nutrients include B vitamins (particularly B1, B2, B3, B5—essential for energy metabolism enzymes), CoQ10 (electron carrier in the respiratory chain), magnesium (required for ATP synthesis and hundreds of enzymatic reactions), iron (component of cytochromes including Complex IV), and antioxidants like vitamin C, vitamin E, and glutathione precursors protecting mitochondria from oxidative stress.

Anti-inflammatory nutrition supports mitochondrial health by reducing systemic inflammation that impairs mitochondrial function. Emphasize omega-3 fatty acids from fatty fish, antioxidant-rich colorful vegetables and fruits, polyphenols from berries, green tea, and dark chocolate, and minimize refined carbohydrates and processed foods that promote inflammation and oxidative stress.

Adequate protein intake ensures availability of amino acids for mitochondrial protein synthesis—both the proteins encoded by mitochondrial DNA and the majority imported from the nucleus. Active individuals should target 1.2-2.0 grams protein per kilogram body weight daily to support tissue repair and mitochondrial maintenance.

Heat and Cold Exposure: Hormetic Stress for Resilience

Controlled exposure to thermal stress—both heat and cold—creates hormetic effects that enhance mitochondrial resilience and function. These mild stressors trigger adaptive responses that strengthen cellular defense systems, including mitochondrial adaptations that improve long-term function.

Heat exposure through saunas, particularly infrared saunas, creates heat shock protein responses that protect cellular proteins including mitochondrial enzymes. Regular sauna use has been associated with improved cardiovascular health, reduced all-cause mortality, and enhanced exercise recovery—benefits likely mediated partly through mitochondrial adaptations. Combining sauna sessions with red light therapy (many infrared saunas can be paired with red light panels) provides complementary mitochondrial benefits.

Cold exposure through cold showers, ice baths, or outdoor winter activities triggers different adaptive pathways. Cold stress stimulates mitochondrial biogenesis in brown adipose tissue (BAT) and skeletal muscle, enhances non-shivering thermogenesis requiring mitochondrial function, and may improve metabolic flexibility. The combination of cold exposure and red light therapy creates comprehensive metabolic stimulus supporting mitochondrial adaptation.

Alternating heat and cold—contrast therapy—provides potentially synergistic benefits through repeated stress-recovery cycles that may enhance mitochondrial stress resilience. Always start conservatively with thermal stressors, gradually increasing duration and intensity as tolerance develops.

Fasting and Time-Restricted Eating

Periodic fasting or time-restricted eating patterns influence mitochondrial function through metabolic switching and autophagy activation. During fasted states, cells shift from glucose-based to fat-based metabolism, changing mitochondrial fuel substrate and potentially enhancing metabolic flexibility—the ability to efficiently utilize different fuel sources.

Extended fasting (16+ hours) activates autophagy—cellular housekeeping processes that remove damaged organelles including dysfunctional mitochondria (mitophagy). This selective removal of impaired mitochondria while sparing healthy ones improves overall mitochondrial population quality. Combined with red light therapy's enhancement of mitochondrial function, fasting may accelerate optimization of cellular energy production capacity.

Time-restricted eating—consuming all daily calories within an 8-12 hour window—provides milder metabolic benefits than extended fasts while being more sustainable long-term. The daily fasting period supports circadian alignment of metabolism, may enhance mitochondrial biogenesis, and allows extended autophagy periods supporting cellular renewal.

Practical integration: Use red light therapy during fasting windows to support energy levels and potentially enhance the metabolic benefits of fasting. Morning red light exposure may help maintain energy and focus during morning fasting periods. Evening sessions after breaking fast support recovery and overnight cellular repair processes.

Sleep Optimization for Mitochondrial Recovery

Quality sleep represents critical recovery time for mitochondrial maintenance and repair. During deep sleep, cellular repair processes accelerate, damaged mitochondria undergo autophagy, and mitochondrial DNA repairs occur. Chronic sleep deprivation impairs mitochondrial function through multiple mechanisms: increased oxidative stress, impaired autophagy, disrupted circadian metabolism, and accumulated mitochondrial damage.

Prioritize sleep hygiene practices supporting mitochondrial recovery: maintain consistent sleep-wake schedules aligning with natural circadian rhythms, ensure complete darkness during sleep (or use blackout curtains/eye masks), keep bedrooms cool (65-68°F optimal for sleep), avoid blue light exposure 2-3 hours before bed, and limit caffeine after early afternoon.

Morning red light exposure supports circadian rhythm entrainment, promoting alertness during day and better sleep at night. Evening red light (near-infrared specifically, avoiding bright visible red light close to bedtime) may support cellular energy without disrupting melatonin production, potentially enhancing sleep quality through improved cellular function.
