How NAD+ Nasal Delivery Works

What Is NAD+?

NAD+ is a coenzyme—sometimes called a "helper molecule"—involved in many metabolic processes, particularly those linked to energy production and cellular repair. It plays a role in functions such as:

• Mitochondrial energy production (ATP generation)
• DNA repair and cellular signaling
• Enzymatic activity related to metabolism

Although NAD+ is naturally present in the body, scientific and public interest in supplementing or restoring its levels is growing—especially in relation to aging and wellness. These uses remain under investigation.

‍

Why Are NAD+ Levels Important?

Some early-stage research suggests that NAD+ levels may decline as part of the natural aging process. Scientists are exploring whether this decline may influence cellular processes, though no definitive conclusions have been reached.

As public interest in proactive health grows, more people are asking their providers about ways to support wellness and vitality. While NAD+ supplementation is one such area of interest, it's important to note that its therapeutic use remains investigational.

Traditional Delivery Methods and Limitations

Oral Supplements

NAD+ supplements taken by mouth are widely available, but some researchers suggest they may have low bioavailability—meaning a significant amount may be broken down before it reaches the bloodstream.

Injections and IV Therapy

Intravenous or injectable forms of NAD+ may bypass digestion, but they typically require in-clinic visits, administration by trained staff, and significant time commitments. These factors can make it inconvenient or inaccessible for everyday use.

NAD+ Nasal Delivery: What to Know

Nasal delivery of NAD+ is being explored as a potential alternative that may offer convenience and ease of use. This method delivers NAD+ via the nasal cavity, an area with a high concentration of blood vessels. Because it bypasses the digestive system, some people view this method as a potentially convenient option to discuss with a healthcare provider. However, its effectiveness has not been confirmed in clinical trials.

Some researchers are also studying how nasal delivery may allow access to areas like the central nervous system via pathways such as the olfactory and trigeminal nerves. However, these investigations are ongoing, and clinical conclusions have not been established.

How It Works: Step-by-Step 

1. Nasal Administration
   NAD+ is applied to the nasal cavity through a spray or atomizer.
2. Potential Absorption
   This area allows for direct contact with vascular tissue, potentially allowing for faster systemic exposure.
3. Central Nervous System Pathways
   Researchers are studying whether nasal administration may allow certain compounds to access the brain, but these mechanisms are not fully understood and remain investigational.

Exploring NAD+ Nasal Delivery in Clinical Conversations 

While NAD+ nasal delivery is not FDA-approved for any medical condition, some licensed healthcare providers are beginning to explore it as a potential route of administration in the context of broader wellness. Scientific research is ongoing into the role of NAD+ in cellular health and how different delivery methods may influence bioavailability.

Because individual responses can vary and formal clinical conclusions have not been established, it’s important to approach NAD+ therapy as an investigational option. Any consideration of this approach should be guided by a licensed healthcare provider who can assess its appropriateness based on your individual needs and medical history.

Is NAD+ Nasal Delivery Safe? 

When prescribed by a licensed healthcare provider and dispensed by a state-licensed compounding pharmacy, NAD+ nasal sprays are prepared according to compounding pharmacy guidelines and regulatory oversight. NAD+ is not FDA-approved.

Eden’s Role in NAD+ Access

Eden is a digital health platform that connects patients to licensed, independent medical providers who can evaluate individual needs and determine whether investigational therapies, like NAD+ nasal delivery, may be appropriate.

We do not manufacture medications or act as pharmacies. If a licensed healthcare provider determines that treatment is appropriate, Eden helps facilitate the prescription and fulfillment process through state-licensed compounding pharmacies in the U.S.

Final Thoughts: Should You Explore NAD+ Nasal Delivery?

For those who are interested in emerging therapies that may complement their overall wellness routines, NAD+ nasal delivery is a topic worth discussing with a licensed medical provider. While the science continues to evolve, Eden makes it simple to start that conversation from the comfort of your home.

We help connect you with medical professionals who can guide your treatment plan, if appropriate, through licensed pharmacies that deliver directly to your door.

NAD+ products discussed here have not been evaluated by the FDA and are not approved to diagnose, treat, cure, or prevent any disease. All therapies are investigational and should be considered only under the guidance of a licensed healthcare provider.
