NAD+ Nasal Spray: What Emerging Research Suggests

What Is NAD+ Nasal Spray?

NAD+ nasal spray is a formulation that delivers nicotinamide adenine dinucleotide (NAD+) via the nasal passage—an area with a dense network of blood vessels. This route is being explored in early research as a way to increase NAD+ availability without oral supplements or injections.

NAD+ nasal spray is not approved by the FDA for the treatment of any medical condition. However, nasal delivery as a method of administration is being studied for its ease of use and potential to support systemic absorption. This route has been investigated for substances that are unstable or poorly absorbed orally, offering a potential noninvasive option for systemic delivery (Shao, 2017).

Why Is Delivery Method So Important?

Oral NAD+ has limited bioavailability, meaning it may break down before reaching the bloodstream in meaningful amounts. That’s why alternative formats, like injections or nasal sprays, are gaining interest.

Because the nasal mucosa is highly vascularized, it may support more rapid systemic absorption. Studies suggest optimizing nozzle angle and spray technique can enhance intranasal penetration (Tesch et al., 2023). Additionally, absorption enhancers such as chitosan or phospholipids may improve uptake via this route (Davis & Illum, 2003).

Why Are People Talking About NAD+ Nasal Spray?

People interested in NAD+ nasal spray may cite:

• Convenience in avoiding pills or injections
• Interest in supporting energy or cognitive wellness
• Preference for stimulant-free approaches to focus

These perceived benefits are theoretical and based on limited data. Individual experiences may vary, and no outcomes can be guaranteed.

When Might NAD+ Nasal Spray Fit Into a Routine?

Some individuals incorporate NAD+ nasal spray into wellness routines focused on:

• Physical activity and rest
• Hydration and nutrient-dense eating
• Sleep hygiene and stress support

This supplement should not replace core health habits or medical advice. A licensed healthcare provider can help assess whether NAD+ fits your wellness strategy.
