NAD+ Nasal Spray (120 Servings)


Intranasal delivery is one of the quickest and most effective ways to deliver NAD⁺ and its precursors, NMN and NR, into the body. The nasal mucosa’s rich blood flow allows for optimal drug absorption while avoiding the first-pass effect.

  • A two-spray serving delivers a highly concentrated liposomal dose containing:
    • 12 mg Liposomal NMN
    • 10 mg Liposomal NAD+
    • 3 mg Liposomal NR
  • 240 sprays = 120 servings
  • Third-party tested for purity (over 99%) and safety – see certificates attached
  • cGMP Certified – This product was made in an FDA approved facility
  • No artificial colours, flavours or preservatives. Non-GMO
  • Gluten-free. Suitable for vegans

Nasal delivery bypasses the GI tract and delivers NAD,⁺ NMN and NR directly to the bloodstream.

Intranasal NAD+ and NAD+ precursors

New & Improved!

Due to high popularity and customer interest, we’ve reformulated & replaced our Pure NAD⁺ Micromist Nasal Spray.

Introducing our new NAD⁺ Complete Nasal Spray, which contains a powerful combination of Liposomal NAD,⁺ NMN & NR, which is fast-acting and easily absorbed by the body.

Why Intranasal Delivery Is Highly Effective

Intranasal delivery is one of the quickest and most effective ways to deliver NAD⁺ and its precursors, NMN and NR, into the body. The nasal mucosa’s rich blood flow allows for optimal drug absorption while avoiding the first-pass effect. 

The first pass effect refers to drugs getting metabolized at specification locations in the body, most often the liver, which results in the drug’s reduced concentration in systemic circulation or at the target site.

“The intranasal administration is an effective way to systemically deliver drugs as an alternative to oral and intravascular routes.” 

Improving NAD⁺ Levels for Better Health

As you age, your levels of NAD⁺ decline and as a result, you may begin to suffer from ageing-related illnesses, fatigue, metabolic issues and inflammation. Keeping levels of NAD⁺ high can help stave off these ageing-related problems.

Many people report improvements in overall health, energy levels, metabolism, fitness & improved sleep while taking NAD,⁺ NAD⁺ precursors & NAD⁺ optimiser supplements.

While there is a lot of uncertainty about the pathways NAD⁺ and NAD⁺ precursors take in the body, we do know that there are differences between them, and they have an affinity for different tissues. We believe the most effective protocol to increase NAD⁺ is through targeting all of these pathways.

Customer Experiences

Feedback from our customers is very important to us, and that’s why we conduct numerous product-related studies with our customers. We’ve received many reports of a quick boost in energy and mental clarity when using our nasal spray products, and an even stronger effect with our newest formulation here.

NAD+ Can Cross the Blood-Brain Barrier

As a protective layer surrounding the brain, the blood-brain barrier’s main purpose is to prevent harmful agents from reaching the brain. Research has shown that certain methods can be used to create a passageway through the barrier in order to allow therapeutic agents to reach their target.

In a study published in September of 2018, NAD⁺ was administered through Intraperitoneal Injection and Intravenous injection in mice. The injections demonstrated that NAD⁺ crosses the blood-brain barrier to enter the hypothalamus intact, in mice.

“In conclusion, our results demonstrate that exogenous NAD⁺ is effectively imported into the hypothalamus and increases hypothalamic NAD content.”  

Neuroprotection from Intransal NAD+ Delivery

In one study on rats with transient focal ischemia, intranasal administration of NAD⁺ was found to significantly increase NAD⁺ levels in the brain, while being neuroprotective.

“We observed that intranasal NAD+ delivery significantly increased NAD+ contents in the brains.”

Intranasal Liposomal Delivery Improves Bioavailability

Intranasal liposomal delivery of NAD,⁺ NMN and NR improves bioavailability by encapsulating and delivering the compounds in their complete form for increased cellular uptake.

“Furthermore, the drugs administered using nasal route have usually higher bioavailability, less side effects and result in higher brain exposure at similar dosage than the oral drugs.” 

Increased NAD+ levels stimulate energy metabolism, DNA repair, and Sirtuin activity. Sirtuins are the longevity-genes shown to be active during caloric restriction and life-extension in many animal models.

  • Boosts Energy Metabolism
  • Promotes Healthy Brain and Cardiovascular Function
  • Anti-Ageing DNA Repair
  • SIRTUIN Activator – NAD+ is required for our longevity genes to work.

Scientists have now confirmed a direct link between falling NAD+ levels and ageing in both animals and human subjects. A breakthrough study published by Harvard scientists in 2013 showed for the first time that some aspects of ageing might be reversible. The research and understanding into NAD+ metabolomics are ongoing, but what the science has highlighted thus far, is the importance of supporting and maintaining our NAD+ levels.

There are currently several human clinical trials underway that are going to help answer this very question. Dr. Sinclair has been leading the charge in this field for years. Watch the video below to hear what Dr. Sinclair has to say about where we are today.
