What to Expect
Days 1 – 3
A noticeable energy lift within 30–60 minutes of your first dose. Many users report sharper focus and reduced mental fog shortly after using — especially when taken before morning activity or workouts.
Week 1 – 2
Improved mental clarity, better recovery from physical and mental stress, and more sustained energy throughout the day. Mitochondrial function begins to improve as NAD+ levels are consistently restored.
Week 4+
Sustained cellular energy, improved metabolic efficiency, and long-term support for DNA repair and healthy aging. Sirtuin activation and NAD+-driven longevity pathways accumulate benefit with continued daily use.

NAD+ Nasal Spray
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.
Administration Protocol
Storage & Handling
⚠️ Ensure nasal passages are clear before spraying to maximize absorption.

What It Does
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.
NAD+ is a critical substrate for ATP production — the primary energy currency of every cell in your body. Supporting NAD+ levels translates directly into improved vitality, stamina, and resistance to physical and mental fatigue.
May improve focus, memory, and mental clarity by supporting the energy demands of neurons and the metabolic processes underlying cognitive performance — leading to increased productivity and overall mental sharpness.
NAD+ activates sirtuins and PARP enzymes — key regulators of DNA repair and cellular aging. Maintaining healthy NAD+ levels is one of the most studied approaches to promoting healthy aging at the cellular level.
Improves energy and accelerates recovery from both physical exertion and mental stress — by restoring mitochondrial efficiency and supporting the metabolic processes that become depleted under sustained demand.
Aids in glucose metabolism and mitochondrial function — supporting insulin sensitivity, fat oxidation, and the overall metabolic processes that govern how efficiently your body converts food into energy.
May reduce oxidative stress and support brain health by activating protective cellular pathways — defending neurons against age-related decline, environmental stressors, and the cumulative damage of chronic inflammation.

The Science
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.
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 a significant portion of their potency before reaching circulation. Lay down for 10 minutes after administration to maximize absorption.
Once in circulation, NAD+ enters cells and is utilized by mitochondria to drive ATP production — the energy conversion process that powers every cellular function. Restored NAD+ levels mean more efficient energy metabolism, reduced fatigue, and improved cellular resilience under stress.
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.
With consistent daily use, NAD+ levels build and stabilize — supporting ongoing cognitive performance, metabolic efficiency, and cellular repair processes. Most customers report noticeable energy and mental clarity improvements within the first 1 to 2 weeks, with deeper metabolic benefits accumulating over continued use.
Why Lavi MD
Most peptide suppliers prioritize volume over patients. We were built differently — by a physician, for patients.
Physician on Staff
Sasson Moulavi, MD
Dispensing Physician · Chayim Therapeutics, LLC

"Every product we offer is something I would prescribe to my own patients. Our formulations are designed for clinical outcomes — not marketing claims."
How We Operate
Built by a Physician, Not a Marketing Team
Lavi MD was founded under physician supervision. Every formulation, every dose, every protocol is reviewed by Dr. Moulavi before it reaches a patient — not outsourced to a contract manufacturer with no clinical input.
We Ship 2-Day Air, Monday & Tuesday Only
We only ship Monday and Tuesday, and every order placed in that window goes out 2-Day Air. That's a deliberate decision. It keeps your order moving quickly and arriving before the weekend, instead of sitting in a carrier facility for days. Most brands don't think that far ahead.
We Treat You Like a Patient, Not an Order Number
Our team includes clinical staff who understand what you're taking and why. If something goes wrong with your order — a warm shipment, a missing component, a question about your protocol — we fix it. No automated runaround.
Important — read before opening
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 the 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 prescribing physician. Most protocols call for 1 to 2 sprays per nostril once daily. Do not exceed the recommended dose without consulting your provider.
If anything appears to be missing from your order, do not discard the packaging. Contact support@lavimd.com and we will make it right.

Three months in. Sharper mornings, no crash, and I actually feel like myself again.
Nadia V. –
The clarity and focus have been great. Only note is that the spray has a slight taste in the back of the throat, which I got used to after a couple of days.
Marcus W. –
I am 47 and the afternoon crash was becoming a daily event. A few weeks on the NAD+ spray and I am getting through the day without reaching for a third coffee. Steadier energy, not a jittery spike.
