NAD+ Nasal Spray
Everything You Need to Know
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in every cell of your body - essential for energy production, DNA repair, and metabolic regulation. Levels decline significantly with age. Nasal delivery is the most direct way to restore them.
- Boosts Cellular Energy - Supports ATP production for improved vitality and stamina.
- Enhances Cognitive Function - May improve focus, memory, and mental clarity.
- Supports DNA Repair and Longevity - Activates sirtuins to promote healthy aging at the cellular level.
- Reduces Fatigue - Improves energy and recovery from physical or mental stress.
- Supports Metabolic Health - Aids glucose metabolism and mitochondrial function.
- Neuroprotective Effect - May reduce oxidative stress and support long-term brain health.
NAD+ is ideal for adults seeking to combat age-related energy decline, improve cognitive performance, or support long-term metabolic and cellular health. Particularly popular with active individuals, biohackers, and anyone over 35 looking to restore NAD+ levels that have naturally declined with age.
NMN and NR are precursors that your body must convert into NAD+ - adding a metabolic step that reduces efficiency and bioavailability. Our nasal spray delivers NAD+ directly, bypassing the digestive system entirely. No conversion required, no loss of potency through the gut.
Yes. DrSeinfeld.com NAD+ Nasal Spray is non-steroidal and contains no toxic fillers or preservatives. Each batch is micro-filtered in our SQF-certified, FDA-registered compounding facility under the oversight of Dr. Amy Seinfeld, D.O. - formulated for consistent purity and potency.
Administer 1 spray into each nostril in the morning or early afternoon. Lay down for 10 minutes after administration to maximize absorption. May be used up to twice daily - max 4 total sprays per 24-hour period. Use daily for best results.
NAD+ nasal spray is generally well tolerated. Mild side effects may include temporary nasal irritation or dryness, mild headache, or lightheadedness in sensitive individuals. These effects are typically short-lived and resolve without intervention.
Administration Protocol
Storage & Handling
Ensure nasal passages are clear before spraying to maximize absorption.

What It Does
Six Reasons Clinicians Recommend NAD+
Nicotinamide Adenine Dinucleotide - a coenzyme your cells depend on for energy production, DNA repair, and metabolic regulation. Delivered via nasal spray for rapid, high-bioavailability absorption.
Boosts Cellular Energy
NAD+ is a critical substrate for ATP production - the primary energy currency of every cell. Restoring NAD+ levels translates directly into improved vitality, stamina, and resistance to fatigue.
ATP | Vitality | StaminaEnhances Cognitive Function
May improve focus, memory, and mental clarity by supporting the energy demands of neurons and the metabolic processes underlying cognitive performance.
Focus | Memory | ClaritySupports DNA Repair & Longevity
NAD+ activates sirtuins and PARP enzymes - key regulators of DNA repair and cellular aging. One of the most studied approaches to promoting healthy aging at the cellular level.
DNA Repair | Sirtuins | Healthy AgingReduces Fatigue
Improves energy and accelerates recovery from both physical exertion and mental stress by restoring mitochondrial efficiency.
Recovery | Endurance | MitochondriaSupports Metabolic Health
Aids in glucose metabolism and mitochondrial function - supporting insulin sensitivity, fat oxidation, and how efficiently your body converts food into energy.
Metabolism | Glucose | MitochondriaNeuroprotective Effect
May reduce oxidative stress and support brain health by activating protective cellular pathways - defending neurons against age-related decline and chronic inflammation.

The Science
How NAD+ Works Inside Your Body
NAD+ levels naturally decline with age - dropping as much as 50% by midlife. Nasal delivery is the most direct and efficient way to restore them without the degradation of oral formats.
Nasal Administration - Morning or Early Afternoon
Administer 1 spray into each nostril in the morning or early afternoon. The nasal mucosa absorbs NAD+ directly into the bloodstream - bypassing the digestive tract where oral NAD+ supplements lose significant potency. Lay down for 10 minutes after administration to maximize absorption.
Higher bioavailability than oral NMN or NR supplementsMitochondrial & ATP Support
Once in circulation, NAD+ enters cells and is utilized by mitochondria to drive ATP production. Restored NAD+ levels mean more efficient energy metabolism, reduced fatigue, and improved cellular resilience under stress.
Mitochondrial efficiency - ATP synthesisSirtuin Activation & DNA Repair
NAD+ is the essential cofactor for sirtuins - a family of proteins that regulate DNA repair, gene expression, and cellular stress responses. By restoring NAD+ availability, you activate these longevity pathways, supporting cellular integrity and healthy aging at a molecular level.
Sirtuin activation - DNA repair - longevity pathwaysSustained Cellular Optimization
With consistent daily use, NAD+ levels build and stabilize - supporting ongoing cognitive performance, metabolic efficiency, and cellular repair. Most customers report noticeable energy and mental clarity improvements within the first 1 to 2 weeks, with deeper metabolic benefits accumulating over continued use.

Before You Use Your Nasal Spray
Your spray ships in two parts. Take 60 seconds to assemble before first use.
Check Your Package Contents
Your nasal spray ships in two parts: the bottle and the pump mechanism. Both are inside the box, protected by inner packaging. Do not discard anything until you have located both pieces.
Do not throw away any packaging until you have fully assembled your spray.Remove the Protective Cap From the Pump
Locate the pump mechanism inside the box. It will have a small protective cap covering the nozzle tip. Remove it and set it aside - you will reuse it to seal the spray between doses.
Attach the Pump to the Bottle
Insert the pump stem into the top of the bottle and press down firmly until it clicks into place and sits flush with the bottle neck. The pump should feel secure and not wobble.
Prime Before First Use
Hold the bottle upright and depress the pump 3 to 5 times until a fine mist appears. This purges any air from the stem. Your spray is now ready to use.
Prime into a tissue - not toward yourself or others.Replace the Cap and Refrigerate
After each use, replace the protective cap over the nozzle. Refrigeration is required. Store upright in your refrigerator away from strong odors. Do not freeze.
Recommended Usage
Use only as directed by your healthcare provider. Most protocols call for 1 to 2 sprays per nostril once daily in the morning. Do not exceed the recommended dose without consulting your provider.
