What is IV NAD+ Therapy?

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell of your body, essential for converting food into energy and keeping your DNA repair systems running. As we age — or through chronic stress, alcohol use, or illness — NAD+ levels naturally decline, which is linked to fatigue, cognitive decline, and slower cellular recovery. IV NAD+ therapy bypasses the digestive system entirely, delivering this molecule straight into the bloodstream for maximum absorption.

How does IV NAD+ Therapy work?

NAD+ sits at the center of your cellular energy production, acting as a key helper molecule in the process that generates ATP — the fuel your cells run on. It also activates sirtuins, a family of proteins that regulate aging, inflammation, and DNA repair. When delivered intravenously, NAD+ rapidly enters tissues including the brain, potentially restoring cellular function faster than oral supplements can.

What forms does IV NAD+ Therapy come in?

IV infusion is the primary delivery method, administered over 2–8 hours in a clinical setting. Some clinics also offer intramuscular (IM) injections for maintenance dosing between full infusion sessions. Oral NAD+ supplements exist but have much lower bioavailability compared to IV delivery.

Where it comes from:

The therapeutic use of NAD+ has roots in the 1960s when South African physician Dr. Harding started using IV NAD in treating alcoholism and addiction — work that was largely overlooked for decades. Modern interest surged in the 2000s as aging researchers like David Sinclair at Harvard began publishing on NAD+ pathways and sirtuins, triggering a wave of clinical interest in IV NAD+ as a longevity and recovery tool.

What does IV NAD+ Therapy help with?

• Brain fog and mental clarity: NAD+ is critical for brain cell energy production, and low levels are associated with sluggish mental performance. Many patients report sharper focus and clearer thinking within the first day or two of an infusion series, likely because neurons get a rapid energy boost when NAD+ availability is restored.
• Chronic fatigue and low energy: When mitochondria — your cells' energy factories — run low on NAD+, they produce less ATP, leaving you feeling exhausted even after rest. IV NAD+ directly refuels this system, with many recipients reporting a meaningful uptick in stamina and vitality after one to a few sessions.
• Addiction recovery support: This is one of the most studied applications of IV NAD+. Addiction depletes NAD+ stores significantly, impairing the brain's natural reward signaling. IV NAD+ has been used to reduce cravings and ease withdrawal symptoms for alcohol, opioids, and stimulants — helping to replenish neurological function during early recovery.
• Anxiety and depression: NAD+ supports the production of serotonin and other neurotransmitters by fueling the enzymes that make them. Some patients receiving IV NAD+ for other conditions report notable mood improvements, and early clinical work in addiction recovery populations suggests reduced anxiety and depression scores.
• Age-related cognitive decline: NAD+ levels drop by as much as 50% between young adulthood and middle age, and this decline is linked to reduced brain resilience and memory. IV NAD+ aims to slow or partially reverse this drop, supporting the sirtuin proteins that maintain brain cell health and protect against neurodegeneration.
• Athletic recovery and performance: Intense exercise accelerates NAD+ consumption as muscles work to repair microscopic damage. IV NAD+ is increasingly used by athletes seeking faster recovery between training sessions, with the theory being that restoring NAD+ speeds up muscle repair and reduces oxidative stress.
• Neurodegenerative disease risk: Conditions like Parkinson's and Alzheimer's are associated with mitochondrial dysfunction and declining NAD+ levels. While IV NAD+ is not a cure, early research suggests it may support the cellular maintenance pathways that help protect neurons from damage over time.
• Post-COVID fatigue (long COVID): COVID-19 appears to deplete NAD+ stores and impair mitochondrial function in ways that persist long after infection. Clinicians working with long COVID patients have begun using IV NAD+ as part of broader recovery protocols, with some patients reporting improvements in energy and cognitive symptoms.
• Sleep quality: NAD+ plays a role in regulating circadian rhythm by supporting SIRT1, a protein that helps set the body's internal clock. Some patients receiving IV NAD+ therapy report improvements in sleep depth and consistency, though this area needs more formal research.

What can IV NAD+ Therapy help prevent?

• Age-related NAD+ depletion (IV therapy can meaningfully slow the cellular decline associated with falling NAD+ levels)
• Relapse in addiction recovery (used as part of structured programs to reduce craving-driven relapse in the early recovery window)

Which foods are rich in IV NAD+ Therapy?

1. Beef liver: One of the richest dietary sources of NAD+ precursors — particularly niacin (vitamin B3) and tryptophan — which the body converts into NAD+.
2. Chicken breast: High in niacin and tryptophan, both direct dietary precursors that the body uses to synthesize NAD+.
3. Wild-caught tuna and salmon: Excellent sources of niacin; fatty fish also provide omega-3s that support the mitochondrial membranes where NAD+ does much of its work.
4. Edamame and legumes: Good plant-based sources of nicotinamide riboside precursors and tryptophan, supporting NAD+ synthesis for those avoiding animal products.
5. Mushrooms (especially cremini and portobello): Notably rich in niacin among plant foods and contain small amounts of naturally occurring nicotinamide riboside, a direct NAD+ precursor.

Practical Tips:

While IV NAD+ delivers the molecule directly and cannot be replicated by diet alone, a diet rich in NAD+ precursors — especially niacin (B3), tryptophan, and nicotinamide riboside — supports your body's own NAD+ production between infusions. Limiting alcohol is equally important, as alcohol actively depletes NAD+ and undermines the benefit of therapy.

What are the side effects of IV NAD+ Therapy?

• Nausea or stomach cramping during infusion (very common; usually resolved by slowing the drip)
• Flushing, warmth, or skin tingling
• Chest tightness or a sense of pressure (common; not dangerous but should be reported to the attending provider)
• Headache during or shortly after infusion
• Fatigue or 'crash' feeling in the hours following infusion
• Lightheadedness or dizziness
• Anxiety or restlessness during infusion
• Muscle aches or cramping
• Bruising or soreness at the IV site

Good to know:

IV NAD+ is considered safe when administered by a trained clinician in a proper setting. Most side effects occur during the infusion itself and can be managed by adjusting the drip rate. Serious adverse events are rare but the therapy should always be delivered in a medically supervised environment.

How much IV NAD+ Therapy should you take?

• Recommended daily: 250–1000 mg NAD+ per infusion session, administered intravenously over 2–8 hours; exact dose determined by a clinician based on goals and tolerance. Loading protocols for addiction recovery often involve daily infusions of 500–1000 mg for 5–10 consecutive days.
• Best time of day: Morning or midday sessions are generally preferred — NAD+ can be energizing, and late-afternoon infusions may interfere with sleep for some individuals.
• With or without food: A light meal 1–2 hours before the infusion is recommended. Arriving fasted or dehydrated can worsen nausea and dizziness during the drip.
• Time to effect: Many patients notice energy, mood, or mental clarity shifts within hours of their first infusion. Full benefits for addiction recovery or chronic fatigue typically require a complete series of 4–10 sessions.
• How long to take it: Intensive loading protocols (daily for 5–10 days) are used for addiction recovery and acute fatigue. Maintenance dosing is typically once monthly or quarterly for longevity and general wellness goals. Cycling is inherent to the IV format — there is no need for intentional 'breaks' during a standard maintenance schedule.
