NAD+ (nicotinamide adenine dinucleotide) has attracted significant attention in longevity research for its role in cellular energy metabolism, DNA repair, and sirtuin activation. At Vitality Texas, our IV therapy program offers two delivery routes for NAD+: IV infusion administered in-clinic and subcutaneous injectable for at-home daily use. This article explains the science, compares the two delivery methods, and describes what to expect from an IV NAD+ session.
The Science Behind NAD+ and Cellular Energy
NAD+ is an essential coenzyme involved in oxidative phosphorylation — the mitochondrial process by which cells convert fuel into ATP. It is also a required substrate for sirtuins, a family of proteins involved in DNA repair, gene expression regulation, and metabolic homeostasis. NAD+ is not optional for cellular function; it is foundational.
Research has documented that NAD+ levels decline with age — a finding with significant implications for cellular energy production and metabolic function. Rajman et al. (2018) reviewed NAD+ depletion mechanisms and the potential of NAD+-boosting approaches in supporting metabolic health. At Vitality Texas, we frame NAD+ therapy as supporting cellular energy and metabolic function — consistent with what the research supports. We do not make anti-aging treatment claims.
IV NAD+ vs Injectable NAD+ — Which Is Right for You?
Vitality Texas offers two NAD+ delivery routes. The right choice depends on your goals, schedule, and where you are in your NAD+ program:
- IV NAD+ (in-clinic):Delivers higher plasma concentration per session than any other delivery method. Requires a 60–120 minute in-clinic visit. Best for periodic high-dose cellular loading, initiation of a NAD+ program, or patients who want maximum single-session impact.
- Injectable NAD+ (subcutaneous, at-home): Lower but consistent plasma levels achieved through daily self-administration. More practical for ongoing maintenance between IV sessions. Does not require clinic visits once prescribed.
Both are physician-supervised at Vitality Texas. Both use compounded NAD+ appropriate for each delivery route. Many patients use both — IV sessions for periodic high-dose loading and injectable for daily ongoing maintenance. Learn more about our injectable NAD+ program and how it fits alongside IV therapy.
The choice between IV and injectable NAD+ depends on your goals and schedule. Dr. Jaqua will advise on the right approach for your specific situation.
What to Expect During an IV NAD+ Session
IV NAD+ infusions require 60–120 minutes in clinic. The infusion rate must be kept slow — infusing NAD+ too quickly can cause transient flushing, chest tightness, or nausea. These sensations are normal and resolve promptly when the infusion rate is adjusted. They are not an allergic reaction.
Many patients report a noticeable energy shift during or after the session — a sense of mental clarity and physical energy. This response varies by individual. Plan for a 2-hour block for your first session while the appropriate rate for your tolerance is established. Subsequent sessions are typically faster once your protocol is dialed in.
Compliance Note — What We Don't Claim
At Vitality Texas, we do not make anti-aging outcome claims for NAD+ therapy. We use “supports cellular energy and metabolic function” framing — consistent with what the research supports. NAD+ therapy is not a longevity intervention, reversal of aging, or treatment for age-related disease. Patients who seek it as a proactive cellular health support tool, under physician guidance, are the appropriate candidates for this protocol.

Frequently Asked Questions
What is NAD+ IV therapy?
NAD+ IV therapy delivers nicotinamide adenine dinucleotide via IV infusion in clinic. It supports cellular energy production, DNA repair, and metabolic function at plasma concentrations higher than oral or injectable NAD+ can achieve in a single session.
How is IV NAD+ different from injectable NAD+?
IV delivers higher plasma concentration per session but requires an in-clinic visit. Injectable NAD+ is self-administered at home for daily ongoing support. Many patients use both. Dr. Jaqua will advise on the right protocol for your goals.
Does NAD+ IV therapy reverse aging?
No. We do not make anti-aging outcome claims. NAD+ supports cellular energy and metabolic function, which are studied in healthy aging research. We use ‘supports cellular energy’ framing — not ‘reverses aging.’
How long does an NAD+ IV session take?
60–120 minutes. NAD+ must be infused slowly to minimize transient flushing or chest tightness. Plan 2 hours for your first session.
How often should I do NAD+ IV sessions?
Dr. Jaqua will design your protocol. A common starting point is 2 IV sessions in the first month, transitioning to monthly IV with daily injectable NAD+ maintenance between sessions.
