NAD+ Therapy

Nicotinamide adenine dinucleotide — known as NAD+ — is a coenzyme found in every living cell. It is essential for energy production, DNA repair, cellular signaling, and the regulation of aging at the molecular level. At Doctor Springs, Dr. Julia Springs, MD, MPH offers NAD+ therapy to help patients in the Tampa area restore this critical molecule, supporting energy, mental sharpness, and cellular resilience from the inside out.

What Is NAD+?

NAD+ is a coenzyme present in every cell of your body. It serves as a key player in hundreds of metabolic reactions, most notably in the mitochondria — the energy-producing structures within your cells. NAD+ acts as an electron carrier in the conversion of food into cellular energy (ATP), making it indispensable for basic biological function.

Beyond energy production, NAD+ activates a family of proteins called sirtuins, which regulate cellular repair, inflammation, and longevity pathways. It also supports PARP enzymes responsible for DNA repair. When NAD+ levels are sufficient, these systems operate efficiently. When levels decline — as they inevitably do with age, stress, and illness — the effects cascade across nearly every organ system.

How NAD+ Therapy Works

Like many essential molecules, NAD+ is poorly absorbed through oral supplementation alone. While precursors such as NMN and NR (nicotinamide riboside) can modestly boost NAD+ levels, intravenous delivery provides the most direct and clinically significant restoration. Dr. Springs administers NAD+ via subcutaneous injections, delivering the coenzyme directly into the bloodstream where it becomes immediately available to cells throughout the body.

Benefits of NAD+ Therapy

Cellular Energy and Fatigue Recovery

NAD+ is the linchpin of mitochondrial energy production. Patients with chronically low NAD+ often experience persistent fatigue that does not respond to rest, caffeine, or lifestyle changes alone. By restoring NAD+ to optimal levels, many patients report a noticeable improvement in sustained energy, physical stamina, and overall vitality — often within the first few sessions.

Cognitive Function and Mental Clarity

The brain is one of the most metabolically demanding organs in the body, consuming roughly 20% of your total energy output. When NAD+ levels decline, cognitive function often suffers first — manifesting as brain fog, difficulty concentrating, forgetfulness, and mental fatigue. NAD+ therapy supports neuronal energy production and may help protect against age-related cognitive decline.

Anti-Aging and Longevity

NAD+ activates sirtuins — a family of proteins that researchers have identified as central regulators of aging and cellular repair. Sirtuin activation promotes DNA repair, reduces chronic inflammation, and supports the maintenance of telomere length. While NAD+ therapy is not a fountain of youth, optimizing NAD+ levels is one of the most evidence-backed strategies for supporting healthy aging at the cellular level.

Metabolic Health and Weight Management

NAD+ plays a direct role in metabolic regulation. It influences how efficiently your body converts food into energy versus storing it as fat. Patients with metabolic syndrome, insulin resistance, or stubborn weight that resists diet and exercise often have depleted NAD+ levels. Restoring them can support improved metabolic efficiency, complementing weight management programs and nutritional strategies.

Mood and Stress Resilience

NAD+ influences neurotransmitter production and the brain's stress-response pathways. Patients undergoing NAD+ therapy frequently report improved mood stability, reduced anxiety, and a greater sense of emotional resilience. This makes it a valuable adjunct for patients navigating hormonal transitions, chronic stress, or recovery from substance dependence.

Athletic Performance and Recovery

For active individuals, NAD+ supports faster muscle recovery, improved oxygen utilization, and reduced exercise-induced inflammation. By enhancing mitochondrial efficiency, NAD+ therapy can help athletes and fitness-oriented patients train harder, recover faster, and sustain performance gains over time.

The Doctor Springs NAD+ Protocol

Administration

NAD+ is administered via subcutaneous injection in the comfort of your own home. 

Monitoring

NAD+ therapy is supported by comprehensive lab work and clinical assessment. Dr. Springs evaluates metabolic markers, mitochondrial function indicators, and inflammatory status to guide dosing and track your response over time. Protocols are adjusted as needed to ensure continued progress toward your health goals.

Side Effects

NAD+ infusions are generally safe and well-tolerated. Some patients experience mild side effects during treatment, including chest tightness, nausea, lightheadedness, or muscle cramping. Serious adverse reactions are rare.

Ideal Candidates

NAD+ therapy may be appropriate for adults experiencing chronic fatigue, cognitive decline, brain fog, metabolic sluggishness, or those seeking proactive support for healthy aging. It is also well-suited for patients recovering from illness, managing neurodegenerative concerns, or looking to optimize athletic performance and recovery as part of a comprehensive wellness plan.

Frequently Asked Questions

What is NAD+ and why is it important?

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every cell of your body. It is essential for converting food into energy, repairing damaged DNA, regulating inflammation, and activating longevity-related proteins called sirtuins. Without adequate NAD+, cellular function declines across virtually every system in your body.

Why do NAD+ levels decline with age?

NAD+ levels naturally decrease as part of the aging process. By middle age, most people have significantly lower NAD+ than they did in their twenties. Chronic stress, poor sleep, excessive alcohol consumption, and sedentary lifestyle can accelerate this decline. Lower NAD+ is associated with reduced energy, impaired cognitive function, and increased disease risk.

How is NAD+ therapy different from taking NMN or NR supplements?

NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside) are NAD+ precursors — your body must convert them into NAD+ after absorption. This conversion process is rate-limited, meaning only a fraction of what you take orally becomes usable NAD+.  NAD+ therapy delivers the active molecule directly into your bloodstream, bypassing the conversion bottleneck and providing clinically significant doses immediately.

How quickly will I feel results?

Many patients report improved energy and mental clarity within the first one to two weeks. The full benefits — including improved sleep quality, mood stability, and physical performance — typically build over the course of the initial loading series. Results vary depending on your baseline NAD+ levels and overall health status.

Can NAD+ therapy be combined with other treatments?

Yes. NAD+ therapy complements many of the integrative treatments offered at Doctor Springs, including hormone replacement therapy, peptide therapy, and glutathione injections. Dr. Springs often designs multi-therapy protocols that leverage synergies between these treatments for comprehensive results.

Is NAD+ therapy safe?

NAD+ therapy has a strong safety profile when administered by a qualified physician. Side effects are typically mild and transient. Dr. Springs conducts a full medical review before recommending NAD+ therapy.

Does insurance cover NAD+ therapy?

NAD+ therapy is not typically covered by insurance. Doctor Springs provides transparent pricing and can discuss costs during your consultation. Visit our pricing page for more details.
