NAD+ Therapy: Supporting Your Body at the Cellular Level
Exploring the benefits of NAD+ and how injectable and dissolvable sheet forms compare
What Is NAD+ — and Why Does It Matter?
NAD+ (nicotinamide adenine dinucleotide) is one of the most important molecules in the human body. It’s a coenzyme found in every cell, where it acts as a kind of cellular workhorse — powering the processes that keep us energized, resilient, and functioning at our best.
From a functional medicine standpoint, NAD+ is especially compelling because it sits at the crossroads of so many systems. Rather than targeting a single symptom, supporting NAD+ is about nurturing the foundational cellular machinery that influences how we feel, perform, and age.
Here’s the catch: NAD+ levels naturally decline as we get older. This decline is driven both by reduced production and by increased consumption from enzymes that ramp up with age and stress. Researchers believe this gradual drop may be one of the contributors to the changes we associate with aging — lower energy, slower recovery, and reduced cellular resilience.
The Many Roles of NAD+ in the Body
NAD+ isn’t a single-purpose molecule. It participates in a remarkable range of essential functions, including:
- Energy production — NAD+ is central to how mitochondria (your cells’ power plants) convert nutrients into usable energy (ATP)
- DNA repair — it fuels enzymes that help repair everyday cellular damage
- Mitochondrial health — it supports the creation and maintenance of healthy mitochondria
- Cellular signaling and metabolism — it helps regulate pathways tied to metabolism, inflammation, and longevity
- Sirtuin activation — it powers a family of “longevity proteins” involved in healthy aging
Because these functions touch nearly every system in the body, NAD+ has become a cornerstone of conversations around energy, healthy aging, metabolic wellness, and recovery.
Potential Benefits of NAD+ Support
Research into NAD+ is active and growing. While much of the most dramatic data still comes from laboratory and animal studies, a number of early human studies point to promising areas where supporting NAD+ may offer benefits, particularly for healthy aging:
- Metabolic wellness — Early studies in older adults have shown improvements in muscle insulin sensitivity, and NAD+ plays a well-established role in glucose and lipid metabolism
- Cardiovascular and vascular support — Some human research has noted modest reductions in blood pressure, improved lipid profiles, and improved arterial compliance in older adults
- Skin health — Nicotinamide, a form of vitamin B3 within the NAD+ family, has been studied for its role in skin protection
- Cellular repair and resilience — NAD+ powers the DNA-repair and antioxidant pathways that help cells recover from daily stress
- Inflammatory balance — NAD+ helps regulate inflammatory pathways, an area of active research interest
- Energy and recovery — Because of its central role in mitochondrial energy production, NAD+ is widely used in wellness protocols aimed at supporting vitality and post-exertion recovery
It’s worth being honest about where the science stands: human research is still emerging, and NAD+ is best understood as a way to support the body’s underlying cellular processes rather than to treat or cure any specific condition. That’s exactly why a personalized, provider-guided approach matters.
Injectable vs. Dissolvable Sheets: How They Compare
One of the most common questions patients ask is which delivery method is right for them. The answer depends on your goals, your lifestyle, and what you’re hoping to achieve. Both forms aim to raise NAD+ availability — they simply take different routes to get there.
Bioavailability (How Much Reaches Your System)
This is the biggest practical difference. NAD+ that’s simply swallowed in pill form is poorly absorbed, because the digestive system breaks much of it down before it reaches circulation.
- Injectable NAD+ bypasses the digestive system entirely, delivering NAD+ directly into the body for higher, more reliable absorption.
- Dissolvable NAD+ sheets dissolve on the tongue, allowing NAD+ to absorb through the tissues of the mouth. This bypasses digestion and offers meaningfully better absorption than swallowed supplements.
Onset and Intensity
- Injectable acts faster and reaches higher concentrations, making it well-suited to those seeking a more immediate, higher-intensity boost.
- Dissolvable sheets typically begin absorbing within roughly 15–45 minutes and support a steadier, gentler approach.
Convenience and Consistency
- Injectable delivers a powerful, intermittent dose but is administered in-office under professional supervision.
- Dissolvable sheets are needle-free and easy to incorporate into a daily routine — simply placed on the tongue to dissolve — which makes them a practical option for consistent, long-term cellular support.
Which Is Right for You?
There’s no universal “best” — it comes down to your priorities:
- Want a higher-intensity, in-office experience? Injectable may be the better fit.
- Prefer a needle-free, easy-to-maintain daily option? Dissolvable sheets may suit you better.
Many people find that the right choice is the one they can stay consistent with, since cellular support works best as an ongoing commitment rather than a one-time event.
What to Expect
NAD+ in both injectable and dissolvable sheet forms is generally well-tolerated. As with any wellness therapy, your experience is most effective and safest when it’s part of a personalized plan. During a consultation, we’ll discuss your goals, health history, and which delivery method and protocol best align with your needs.
A Functional Medicine Perspective
At our practice, we approach NAD+ through a functional medicine lens — focusing on optimizing the body’s foundational systems rather than simply managing symptoms. NAD+ therapy fits naturally into that philosophy, supporting the cellular health that underpins energy, recovery, and healthy aging. The goal isn’t a quick fix; it’s giving your cells the resources to do what they do best.
