NAD+ has become one of the most talked-about molecules in longevity and wellness, showing up in podcasts, biohacking forums, and conversations about aging well. Behind the hype, though, is real biology worth understanding before you book an IV.

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell that helps convert food into cellular energy and supports DNA repair and healthy cellular function. NAD+ IV therapy delivers it directly into the bloodstream, and people often pursue it for energy, mental clarity, recovery, and healthy aging. At Quantum Functional Medicine in Carlsbad, NAD+ is offered as part of an individualized, medically guided approach.

What NAD+ actually does in the body

NAD+ is essential to how your cells produce energy in the mitochondria, the 'power plants' inside each cell. It also plays a role in DNA repair and in the activity of longevity-related proteins. Here's the catch: NAD+ levels naturally decline with age and can be further depleted by chronic stress, poor sleep, inflammation, and heavy alcohol use. That decline is part of why researchers are so interested in NAD+ and aging.

Why deliver NAD+ by IV?

Taken as an oral supplement, NAD+ and its precursors face digestion and absorption hurdles. Intravenous delivery bypasses the gut, allowing higher, more predictable availability. Because NAD+ IVs are typically infused slowly, the experience is unhurried by design.

What people use NAD+ IV therapy for

• Energy and fatigue: supporting mitochondrial energy production
• Mental clarity and focus: many report reduced brain fog
• Healthy aging: as part of a broader longevity strategy
• Recovery: from demanding training, travel, or periods of high stress
• Metabolic and cognitive support: as an adjunct to lifestyle change

It's worth being candid: research on NAD+ therapy is still evolving, and much of the enthusiasm is ahead of large clinical trials. Reputable clinics present it as a promising, well-tolerated option for many people, not a miracle cure.

What to expect during a NAD+ IV

After a brief evaluation to confirm you're a good candidate, NAD+ is infused slowly over the course of a session. Infusing too quickly can cause temporary sensations like flushing, chest tightness, or nausea, so the drip is intentionally paced for comfort. Many people combine NAD+ with other targeted nutrients as part of a broader IV therapy plan, and pair it with detoxification and lifestyle support.

What to expect at Quantum Functional Medicine in Carlsbad

Our Carlsbad clinic serves North County San Diego with medically supervised IV therapy tailored to your goals and health history, not a menu you order from blindly. That means a clinician helps determine whether NAD+ makes sense for you, at what cadence, and alongside what else.

Frequently asked questions

What does NAD+ IV therapy feel like?

Most people tolerate it well when infused slowly. Going too fast can cause temporary flushing or chest tightness, which is why sessions are paced and monitored.

How often do people get NAD+ IVs?

It varies. Some start with a short series of sessions and then move to occasional maintenance. A clinician can help you set a cadence based on your goals and response.

Is NAD+ IV therapy proven to slow aging?

NAD+ is central to cellular energy and repair, and levels decline with age, but human research on NAD+ therapy is still emerging. It's best viewed as one part of a comprehensive healthy-aging plan, not a standalone anti-aging cure.

Who should avoid it?

As with any IV therapy, a medical evaluation is important. Pregnancy, certain medical conditions, and some medications may make it unsuitable, which is why medical supervision matters.
