NAD+ Nasal Spray. The brain-targeted delivery your cells have been waiting for.
NAD+ is the coenzyme that powers every cell in your body — from energy production and DNA repair to the sirtuin proteins most linked to how fast you age. The problem is that by your 50s, NAD+ levels have dropped by roughly half from their peak. The effects hit hardest where you feel them most: your energy, your focus, your mental sharpness.
NAD+ Nasal Spray is formulated to reach the brain efficiently by traveling through the olfactory nerve pathway — a direct neurological route that bypasses the digestive system entirely. No needles. No injections. One spray, once or twice daily.
For patients who want NAD+ targeted toward cognitive function and daily mental clarity, the nasal spray delivers a convenient, needle-free option that fits into any morning routine.
NAD+ Nasal Spray
NAD+ and the brain — the numbers behind the science.
Declining NAD+ doesn't just slow your body down. It changes how your brain runs. These are the figures worth knowing.
Individual results vary. Olfactory delivery data reflects research on intranasal compounds generally; specific NAD+ brain uptake via intranasal route has been studied in animal models and is an active area of human research. NAD+ Nasal Spray is a compounded preparation used off-label for longevity and cognitive wellness. Results are not guaranteed.
A direct neurological route. No digestive system. No liver metabolism.
Intranasal delivery uses one of the body's oldest and most direct pathways — the olfactory nerve — to move compounds from the nasal cavity toward the brain without passing through the gastrointestinal tract.
Nasal Application
A single spray is applied to the nasal mucosa — the highly vascular tissue lining your nasal cavity, rich in nerve endings and capillaries.
Mucosal Absorption
The compound absorbs rapidly through the nasal mucosa. This bypasses the digestive system and avoids first-pass metabolism in the liver — the process that degrades much of what you swallow.
Olfactory Nerve Pathway
The olfactory nerve runs directly from the nasal cavity to the brain. Intranasal compounds travel along this route toward the olfactory bulb and from there into surrounding brain structures.
Reaches the Brain
Delivery via the olfactory pathway can reach central nervous system tissue in approximately 20 minutes — without passing through the blood-brain barrier as a limiting step.
What patients use NAD+ Nasal Spray for.
Nasal Spray vs. NAD+ Injection.
Both deliver NAD+. The right choice depends on your goals — and many patients use both.
NAD+ Nasal Spray
Brain-targeted • Needle-free
NAD+ Injection
Systemic • Highest bioavailability
Many patients use both.
The spray handles daily cognitive support and brain-targeted delivery. The injection handles full-body NAD+ saturation — energy production, metabolic support, DNA repair. Used together, they complement each other without overlap. Your care team can recommend the right protocol for your goals.
What NAD+ actually does once it's inside your cells.
Sirtuin Activation
Your body encodes seven sirtuin proteins — SIRT1 through SIRT7 — that regulate aging pathways, inflammation, and metabolic function. Every one of them requires NAD+ as a co-substrate to work. Without adequate NAD+, sirtuin activity declines sharply with age. Restoring NAD+ levels reactivates these longevity enzymes.
Mitochondrial Energy Production
NAD+ is the central electron carrier in the mitochondrial electron transport chain — the process your cells use to generate ATP, the molecule that powers nearly every biological function. As NAD+ falls, mitochondria become less efficient. The result is the fatigue, mental sluggishness, and slow recovery that accumulate with age.
DNA Repair via PARP
PARP enzymes are your body's first responders for DNA damage — and they consume NAD+ to function. Each repair event depletes cellular NAD+. Maintaining adequate levels ensures PARP enzymes have the fuel they need to keep up with daily DNA strand breaks, protecting genomic stability over time.
Safety and what to expect.
NAD+ nasal spray is generally well-tolerated. Here is what most patients experience.
Tolerability
NAD+ Nasal Spray is generally well-tolerated across the patient populations using it. The most commonly reported effects are mild nasal irritation or a brief burning sensation upon application — typically transient and self-resolving. Most patients notice no adverse effects with regular use.
What to Expect
Results build over time with consistent use. Some patients notice improved mental clarity or energy within the first few weeks. Cognitive and longevity-related benefits associated with NAD+ restoration — including improved mitochondrial function and sirtuin activity — tend to compound over months of consistent use.
When to Contact Your Care Team
Reach out to your Obsidian Genetics provider if you experience persistent nasal discomfort, unexpected symptoms, or have questions about dosing. Your care team monitors your response and can adjust your protocol based on how you're doing.
Prescribed and monitored by your care team.
All Obsidian Genetics prescriptions are issued by licensed providers following a clinical intake review. Your provider reviews your health history, goals, and current medications before prescribing. NAD+ Nasal Spray is not appropriate for everyone — your provider will determine whether it is right for you.
Frequently asked question
How does the nasal spray differ from an injection?
The primary difference is delivery route and intended focus. The nasal spray reaches the brain via the olfactory nerve pathway — a direct neurological route that makes it particularly suited for cognitive and neurological applications. The injection delivers NAD+ directly into the bloodstream for full-body systemic availability. Both work through the same downstream mechanisms once NAD+ enters cells. Many patients use both formats to cover systemic and brain-targeted delivery simultaneously.
Does the nasal spray actually reach the brain?
The olfactory pathway — the route the nasal spray uses — is a well-documented mechanism in neuroscience and drug delivery research. Intranasal compounds can travel along the olfactory nerve from the nasal mucosa toward the brain in approximately 20 minutes, without being blocked by the blood-brain barrier. Research on NAD+ specifically via this route is ongoing — current evidence includes animal models and mechanistic studies. Your care provider can walk you through the current science.
When will I notice results?
Timelines vary by individual. Some patients report improved clarity and energy within a few weeks of consistent daily use. The cellular-level effects associated with NAD+ restoration — sirtuin activation, improved mitochondrial efficiency, reduced DNA damage accumulation — build over months rather than days. Think of it as restoring a depleted resource over time, not a stimulant providing an immediate effect.
How do I use NAD+ Nasal Spray?
Your prescribing provider will give you exact dosing instructions based on your protocol. Most patients use one to two sprays daily, typically in the morning. Apply to one or both nostrils as directed, breathe in gently through the nose after each spray. Store as instructed — compounded preparations typically require refrigeration.
Are there any side effects?
NAD+ Nasal Spray is generally well-tolerated. The most commonly reported effects are mild transient nasal irritation or a brief burning sensation immediately after application. These effects are typically short-lived and resolve on their own. Systemic side effects are uncommon at therapeutic doses. If you experience anything unexpected or persistent, contact your Obsidian Genetics care team.
Is NAD+ Nasal Spray FDA-approved?
NAD+ Nasal Spray is a compounded preparation — it is not an FDA-approved drug product. It is prepared by a licensed compounding pharmacy and prescribed by a licensed provider for off-label wellness and longevity use. Compounded medications are legal and widely used in telehealth and specialty care when a commercially available FDA-approved equivalent does not exist. Your provider oversees the full prescribing and monitoring process.
Compounded Medication Notice: NAD+ Nasal Spray is a compounded preparation. It is not an FDA-approved drug product. Compounded medications are not reviewed by the FDA for safety, efficacy, or manufacturing standards. This product is prescribed by a licensed provider and prepared by a licensed compounding pharmacy for individual patient use. It is intended for off-label wellness and longevity purposes. Results are not guaranteed and individual outcomes vary.
