NAD+ Nasal Spray
1000mg / 10ml · Intranasal Delivery
Our NAD+ Nasal Spray delivers 1000mg of pharmaceutical-grade Nicotinamide Adenine Dinucleotide directly through the nasal mucosa, bypassing digestion entirely for rapid systemic absorption and maximum bioavailability.
Cellular Energy & Mitochondrial Support
NAD+ is a critical coenzyme central to energy metabolism. It powers the mitochondria — your cells' energy factories — converting nutrients into ATP for sustained physical and mental energy throughout the day.
DNA Repair & Anti-Ageing
NAD+ activates sirtuins and PARP enzymes responsible for DNA repair and cellular maintenance. Intranasal delivery restores declining NAD+ levels with age more efficiently than oral supplementation.
Cognitive Performance
By supporting neuronal energy metabolism and reducing neuroinflammation, NAD+ helps sustain mental clarity, focus, and neuroplasticity — with intranasal absorption ensuring rapid brain bioavailability.

How to Use
Prime the Spray
Before first use, pump 3–4 times into the air to prime the nozzle for consistent dosing.
Administer
Tilt head slightly forward, insert the tip gently into one nostril, and press once while inhaling slowly.
Daily Protocol
Use as directed. For best results, administer in the morning on an empty stomach. Store upright, away from heat.
Why Intranasal Delivery?
The nasal mucosa provides direct access to systemic circulation, bypassing first-pass metabolism. This means faster onset, higher bioavailability, and more predictable absorption compared to oral or sublingual routes.
