What it is
What longevity medicine means at Axiva
A physician-supervised way to raise NAD+, the coenzyme that keeps your cells working — delivered as a direct infusion, a gentler precursor, or a quick injection, and adjusted for your comfort.
Longevity medicine at Axiva centers on raising NAD+, a vital coenzyme that keeps your cells running smoothly. Each protocol supports cellular energy, DNA repair, antioxidant defenses, and metabolic balance by increasing NAD+ levels. You can receive NAD+ directly through IV infusion, or the patented Niagen® (NR) precursor your body converts into NAD+, with an optional Longevity Synergy Enhancement IV to amplify results. NAD+ and Niagen® (NR) intramuscular injections offer a faster, lower-downtime alternative. Every session is delivered under real-time medical supervision and adjusted for your comfort.
NAD+ keeps your cells running smoothly — much like oil keeps an engine performing at its best.
How it helps
What raising NAD+ actually does
Four ways a higher NAD+ level supports healthy aging from the cellular level — in plain terms.
Powers cellular energy
NAD+ is a vital coenzyme that keeps your cells running smoothly — much like oil keeps an engine performing at its best. Raising it supports steady, usable energy.
Supports DNA repair
Higher NAD+ availability supports the cellular machinery that maintains and repairs DNA as you age.
Strengthens antioxidant defenses
NAD+ underpins the antioxidant systems that protect cells from everyday oxidative stress.
Balances metabolism
By supporting how cells produce and use energy, raising NAD+ contributes to healthier metabolic balance.
Who it’s for
A fit for healthy-aging goals
Advanced longevity medicine may suit you if you want to support healthy aging from the cellular level.
Step-by-step
A physician-led path
A simple route from consultation to your personalized NAD+ or Niagen® (NR) protocol.
Consultation & screening
Our medical team reviews your health history, goals, and baseline to determine whether NAD+ or Niagen® (NR) therapy is safe and appropriate for you.
Personalized protocol
Choose direct NAD+ IV, the gentler Niagen® (NR) IV, or quick IM injections. We tailor your plan and frequency to your goals — with an optional Synergy Boost where it fits.
Treat & monitor
Clinicians administer your infusion in real time, adjusting the rate for comfort, then guide ongoing maintenance through membership tiers.
Our therapies
NAD+ & Niagen® (NR) options
Medical-grade NAD+ and patented Niagen® (NR), delivered by licensed clinicians with evidence-based protocols.
Direct NAD+ IV therapyActive coenzyme
NAD+, the active coenzyme (500mg, ~240 minutes), delivered directly into your bloodstream with the infusion rate adjusted in real time for comfort.
Niagen® (NR) IV therapyPrecursor
An advanced Nicotinamide Riboside infusion (500mg, ~50 minutes) delivered steadily for comfort, letting your body convert the precursor into NAD+.
NAD+ IM injectionsTime-efficient
NAD+ delivered into muscle for rapid absorption, offering many of the same energy, clarity, and metabolic benefits in a faster, time-efficient visit.
Niagen® (NR) IM injectionsGentle
A gentler precursor approach via IM injection to support mitochondrial function, DNA repair, and healthy aging in a short appointment or as a boost.
Longevity Synergy Enhancement IVOptional add-on
A formula of B Complex, B12, Magnesium, Vitamin C, and Glutathione (~45 minutes) selected to optimize NAD+ function — standalone or added to any treatment.
Ongoing care is available through tiered membership — Essential, Enhanced, and Premium — pairing 1, 2, or 4 monthly IVs with a complimentary Synergy Boost, IM injections, and member discounts. Sessions are administered in heated massage chairs with Wi-Fi so you can relax, stream, or work.
Essential
One monthly IV, with a complimentary Synergy Boost and member pricing.
Enhanced
Two monthly IVs plus IM injections and member discounts.
Premium
Four monthly IVs for the most consistent, ongoing support.
The science
What the research shows
These are elective wellness therapies, grounded in clinical research and delivered under physician supervision. Individual results vary.
In published research, Niagen® (NR) raised intracellular NAD+ by up to 20.7% — supporting cellular energy and healthy aging.

NAD+ vs Niagen® (NR)
Two routes to the same coenzyme
NAD+ hands your cells the finished coenzyme; Niagen® (NR) supplies the precursor they convert into it. Both are physician-supervised — the right choice depends on your goals.
| Direct NAD+ IV | Niagen® (NR) IV | IM injections | |
|---|---|---|---|
| What it delivers | The active coenzyme, directly | A precursor your body converts | NAD+ or Niagen® (NR), into muscle |
| Typical session | About 240 minutes (500mg) | About 50 minutes (500mg) | A short appointment |
| Feel | Rate adjusted in real time for comfort | Steady and generally gentler | Brief, localized sensation |
| Best when you want | Immediate, direct delivery | A gentle, steady infusion | Speed and lower downtime |
Safety & candidacy
Safety, oversight & candidacy
We prioritize your health and safety at every step — and we won’t start treatment unless it’s right for you.
01Who is not a candidate?
Contraindications include pregnancy, active breastfeeding, certain hormonal conditions, and specific gastrointestinal disorders. A thorough health screening determines whether these therapies are safe and appropriate for you.
02What are the possible side effects?
Mild nausea, headache, or fatigue may occur early in NAD+ therapy and are typically temporary. Niagen® (NR) IV side effects are rare and generally mild, such as tingling, congestion, or head and ear pressure.
03Is long-term use safe?
Our therapies are grounded in clinical research and administered under physician supervision, with regular monitoring and dose adjustments. These are elective wellness therapies, not intended to diagnose, treat, cure, or prevent any disease; individual results vary.
Questions
Frequently asked questions
What will the NAD+ or Niagen® (NR) IV therapy feel like?
NAD+ infusions require careful rate management, and some patients notice mild warmth or tingling if the pace is too brisk — we adjust in real time for your comfort. Niagen® (NR) IV flows steadily and is generally gentler, and IM injections involve only a brief, localized sensation.
What’s the main difference between NAD+ and Niagen® (NR)?
NAD+ delivers the active coenzyme directly to your cells, while Niagen® (NR) provides a precursor your body converts into NAD+. Think of NAD+ as handing your cells the finished key, and Niagen® (NR) as supplying the materials to make it.
Which option is right for my goals?
Choose NAD+ IV if you want immediate delivery and don’t mind responsive rate adjustments. Opt for Niagen® (NR) IV if you prefer a gentler, steady precursor infusion. Our clinicians help you decide based on your health history and desired outcomes.
Is there downtime, and how should I plan my day?
NAD+ IV infusions typically take about four hours, while Niagen® (NR) IV averages around 50 minutes. We recommend staying hydrated and planning a relaxed schedule afterward; most patients resume normal activities without issue.
What results can I expect, and when?
Many patients notice energy boosts and improved mental clarity within the first few days. Over the first month, enhanced vitality, better sleep, and more efficient metabolism often emerge. Long-term results vary by individual.
