NAD+ Nasal Spray

Enhance energy, focus, and recovery
support
All the benefits of NAD+, no needles required. A simple daily spray that supports cellular energy, mental clarity, and recovery.
No insurance required
NAD+ is a coenzyme found in every cell in your body. It drives energy production, DNA repair, and brain function. Your levels decline significantly with age, and stress, poor sleep, and alcohol speed that up.
Your mitochondria use NAD+ to convert food into cellular energy. It also activates sirtuins, enzymes that repair DNA and maintain your cells. Oral supplements break down in digestion. Nasal delivery bypasses the gut and enters the bloodstream through the nasal membrane.
Nasal sprays offer a needle-free alternative with rapid absorption through the nasal membrane. No clinic visits, no injections. Just a quick daily spray you can do anywhere. Ideal for people who want the benefits of NAD+ without needles.

Every process in your body runs on NAD+.
It fuels your cells, powers your brain, and drives recovery. But levels drop significantly with age. By your 40s, you may have half the NAD+ you had at 20. Most people feel it as fatigue, brain fog, and slower recovery. A daily nasal spray is the simplest way to restore it.

How NAD+ Nasal Spray works in the body
Powers
cellular energy
NAD+ is essential for mitochondrial function. When levels drop, your cells produce less energy and fatigue follows. Injections help restore what your body has lost.
Repairs DNA
& supports longevity
NAD+ activates sirtuins, enzymes critical for DNA repair and cellular maintenance. Declining NAD+ levels are a key factor in age-related decline.
Boosts
brain function
NAD+ supports the neurotransmitter activity behind focus, memory, and mental clarity. Maintaining healthy levels helps keep your mind sharp as you age.

Talking with a clinician and knowing where my treatment comes from takes so much of the sketchiness out of this.

Injections are effective but some people prefer a needle-free option. The nasal spray gives you daily NAD+ support with zero friction.
NAD+ is naturally produced by your body. Some people experience mild nasal irritation or a slight taste in the back of the throat. These are typically mild and short-lived. Your clinician reviews your health history before prescribing and can adjust your protocol anytime.
