Question 1

What is NAD+ and why does it decline with age?

Accepted Answer

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell. It is essential for energy production (the mitochondrial electron transport chain), DNA repair (via PARP enzymes), and longevity signaling (via sirtuins — proteins activated by caloric restriction and exercise). NAD+ declines by approximately 50% between ages 40 and 60. This decline is associated with reduced cellular energy, impaired DNA repair, increased inflammation, and metabolic dysfunction.

Question 2

What are the benefits of NAD+ therapy?

Accepted Answer

Clinical and research data supports: increased cellular energy and reduced fatigue, improved cognitive function and mental clarity, enhanced DNA repair capacity, activation of sirtuin longevity pathways, improved insulin sensitivity, and reduction of neuroinflammation. NAD+ is also used in addiction medicine — IV NAD+ has shown effectiveness in reducing withdrawal symptoms and cravings for opioids, alcohol, and stimulants. Many patients describe a dramatic improvement in energy and mental clarity within hours of an IV infusion.

Question 3

What is the difference between IV NAD+, injectable NAD+, and oral precursors (NMN/NR)?

Accepted Answer

IV NAD+ delivers the coenzyme directly into the bloodstream — bypassing digestion entirely and achieving the highest cellular concentrations. Injectable NAD+ (subcutaneous or intramuscular) provides good bioavailability with more convenience than IV. Oral precursors — NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside) — are converted to NAD+ through cellular metabolic pathways, but bioavailability and conversion efficiency vary. IV is the most potent acute intervention; oral precursors are used for long-term maintenance between IV or injectable treatments.

Question 4

What does NAD+ IV therapy feel like?

Accepted Answer

IV NAD+ is known for causing transient sensations during infusion — nausea, chest tightness, muscle cramps, and a feeling of pressure — particularly at higher infusion rates. These are not dangerous but can be uncomfortable. Slowing the infusion rate eliminates or minimizes them. Most patients report that the post-infusion feeling (clarity, energy, reduced brain fog) is well worth the temporary discomfort during the drip. Sessions typically run 2–4 hours.

Question 5

How often should I do NAD+ therapy?

Accepted Answer

For general anti-aging and energy: an initial series (often 3–5 IV sessions over 1–2 weeks) followed by monthly or quarterly maintenance. For addiction recovery support: intensive protocols of daily IV over 4–10 days are used in addiction medicine settings. Injectable NAD+ for maintenance is often given 2–3x weekly subcutaneously. Your physician will recommend a protocol based on your goals and baseline health.

Question 6

Is NAD+ safe?

Accepted Answer

NAD+ is a naturally occurring molecule in every human cell — it is not a foreign compound. At therapeutic doses, serious adverse events have not been reported. The main safety consideration is infusion rate with IV administration: too-fast infusion causes the transient discomfort described above. Patients with cardiac arrhythmias should discuss IV protocols with their physician before starting.
